How do I override the Ruby and Ruby DevKit installdir with Chocolatey? - ruby

I am somewhat new to chocolatey, having installed a few packages in the past on Windows 8, and I have come to like it.
I have noticed that chocolatey installs the packages in the default Windows program directory (i.e. "Program Files x86" or so). Maybe there is more to that that I am missing.
For the specific case of Ruby 2.1.5 and Ruby DevKit, I have a couple of questions:
How can I ensure I install the x64 versions of Ruby, and Ruby DevKit using chocolatey?
How can I set a custom installation directory from chocolatey?
I know there is some information about changing the install directory, but the arguments syntax are dependent on the install system used (if any) by the specific package being installed, in this case, Ruby & Ruby DevKit. I am yet to find what would be the CLI installation string for ruby and ruby devkit on windows. Any help is greatly appreciated. Thanks

Forewarning
Parts of Ruby, coming from *nix, do not like spaces. Gems is one of them. This is not a Chocolatey thing, just an FYI in case you DO run into issues once you put it into Program Files. It likely won't work there, so if you run into problems, move it somewhere else.
The installer also doesn't really update permissions if I recall correctly, so you are on your own to make sure your permissions are good so you can run it e.g. Program Files is Administrators writeable only, which you won't have unless you are running an administrative prompt (this is UAC, it removes you from the Administrators group in non-elevated processes).
Guarantee x64?
If you are on a 64-bit system and a package has x64 urls in it, you will get the 64-bit version of that software unless you specifically use -x86 to force the 32-bit version.
Looking at Ruby 2.1.5 package files - we see the chocolateyInstall.ps1 has this line (note the $url64, so we are good):
Install-ChocolateyPackage "$packageId" 'exe' "$silentArgs" "$url" "$url64" -checksum $checksum -checksum64 $checksum64
Looking at Ruby2.DevKit package files - wee the chocolateyInstall.ps1 has this line (again using the x64 url):
Get-ChocolateyWebFile 'ruby2.devkit' "$file" -url "$url" -url64bit "$url64" -checksum "$checksum" -checksum64 "$checksum64" -checksumType "$checksumType"
Customize Install Folder
Usually you would pass the native switch for changing the directory through installargs. However these packages, due to the known issues above, use Chocolatey's Get-BinRoot to determine where to install themselves.
Chocolatey's Get-BinRoot
Get-BinRoot uses an environment variable named ChocolateyBinRoot (set by default to $env:SystemDrive\tools) to determine where to put certain software that doesn't really qualify for Program Files. You can set that where ever you want, including Program Files folders and it will use that location instead.
Installing Ruby and DevKit for v2
choco install ruby -version 2.1.5
If in cmd.exe refreshenv otherwise close and reopen shell.
choco install ruby2.devkit (note the ruby2)
Check the config.yml in the DevKit folder to see if it picked up the ruby installation, otherwise set it and run ruby dk.rb install (you may need force) in the devkit folder to install it into ruby. For more info, please see DevKit.
If in cmd.exe refreshenv otherwise close and reopen shell.
Now I'd like to say you can install gems, but you still need to deal with updating the ssl certificate for rubygems.org. I have an example on vagrant-windows-puppet.
Done.

How to enforce bundle install location

I come from a Python and JavaScript background.
When developing a JavaScript project, dependencies are installed in a node_modules directory in the project root.
When developing Python project, typically virtualenvwrapper is used. In this case dependencies are installed in a virtual environment, which is located in ~/.virtualenvs/<project_name> by default.
Now I need to use a ruby tool for a project. The tool that appears to be the most promising for a similar setup as described above, is bundler.
However, the default installation location for bundler is system-wide. I consider this to be harmful.
For one of my systems, it will prompt for a password, at which point I can still abort.
However, for my other system I can write into the global ruby installation. I'm using a homebrew installed ruby here. Bundle will just install dependencies globally.
I know I can specify the installation location by adding --path, but this is easy to forget.
One way to enforce an installation path is by committing .bundle/config. It would just have to contain this:
---
BUNDLE_PATH: "."
However, some googling around shows that it's not adviced to commit this file.
What is the recommended way to prevent accidental global installations using bundler?
Who's to say it will be accidental? It really depends on what context you're talking about here. I have my Ruby set up so that bundle install works without requiring sudo, it's all done through rbenv automatically. The same is true with rvm if done as a user-level install.
When it comes to deploying apps and you want to make sure it's deployed correctly, that's where tools like Capistrano come into play: Create a deployment script that will apply the correct procedure every time.
Checking in a .bundle/config is really rude from a dev perspective, just like checking in any other user-specific preferences you might have. It causes no end of conflict with other team members.

Installing mingwrt into the haskell-platform without mingw-get

The haskell-platform (2014.2.0.0) ships MingGW, but without mingw-get. However, to compile the setlocale bindings for haskell I need locale.h, which is part of mingwrt.
In a usual mingw installation I would use mingw-get to install mingwrt, but since it's not included in the haskell-platform that doesn't work out of the box.
What would be the usual way of installing mingwrt without mingw-get?
Install MSYS[^1]
Download version 1.0.11 of MSYS. You'll need the following files:
MSYS-1.0.11.exe
msysDTK-1.0.1.exe
msysCORE-1.0.11-bin.tar.gz
The files are all hosted on haskell.org as they're quite hard to find in the official MinGW/MSYS repo
Run MSYS-1.0.11.exe followed by msysDTK-1.0.1.exe. The former asks you if you want to run a normalization step. You can skip that.
Unpack msysCORE-1.0.11-bin.tar.gz into D:\msys\1.0. Note that you can't do that using an MSYS shell, because you can't overwrite the files in use, so make a copy of D:\msys\1.0, unpack it there, and then rename the copy back to D:\msys\1.0.
[^1]:Setting up a Haskell development environment on Windows

Should I enable RubyGems by default when installing ruby on Windows?

I've decided to have a play around with ruby so I've downloaded the windows one click installer. One of the options in the installer which isn't selected by default is to "Enable RubyGems" which automatically enables RubyGems by pre-appending 'rubygems' to the RUBYOPT environment variable.
Being completely new to Ruby I must admit that I have no idea what that means in terms of the impact it will have as I start developing programs in Ruby.
For one, I don't know what Ruby Gems are...but I also don't know how critical they are to ruby development. Should I just enable them by default or should I wait until I find that I definitely need them?
RubyGems or simply gems are Ruby packages or libraries that you can install and use in your Ruby programs. So you definitely will need them at some point in time and therefore you should enable them. When you will see that you need to install gem named "xxx" then you just need to run from command line:
gem install xxx

Ruby cannot find sqlite3 driver on windows

I am trying to set up Ruby on Rails on windows. I am using the Flash Rails distribution that looks pretty good, but there is an issue with sqlite3. I found the threads telling me to install version 1.2.3, which installed fine. I'm using ruby 1.9.0, and every time I try and run a script (e.g. rake db:create) that uses the database I get an error message "no driver for sqlite3 found".
This apparently is a missing sqlite3.dll, but I have the dll in my %PATH%, and I have also tried copying it into the directory where I am running the script from, the directory where the sqlite3 ruby code lives.
Does anyone have any ideas? If possible I want all teh ruby stuff to be self contained so I can use it from a pen drive.
EDIT: To clarify, I already used gem install to install the ruby-sqlite3 gem - it is just non functional as it cannot find the sqlite3.dll (even though it is actually present in a directory on my %PATH%)
EDIT PART 2: After doing some more digging, the problem appears that ruby will not load the sqlite3_api.dll. I have copied it all over my filesystem, I just get a failure to read file. Other dll libraries in the same directory (e.g. zlib.dll) work fine!
I tried installing the dlls into system32, and that did not work either.
The problem put simply is that sqlite3-ruby 1.2.3 is not compatible with ruby 1.9. This is caused because ruby 1.9 does not use .dll files for c libraries it uses .so files instead. Additionally, since sqlite3_api.dll is written against msvcrt-ruby18.dll. This means that it specifically only will support ruby 1.8.*.
The good news is that there is a fat binary version that will support both ruby 1.8 and ruby 1.9. Uninstalling all former versions of sqlite3-ruby and then installing this one. (You may have to manually delete some versions the gem after uninstalling.) in order to install it use
install sqlite3-ruby --source http://gems.rubyinstaller.org
for more information see this website
Try installing the sqlite3-ruby gem:
gem install sqlite3-ruby
Something similar happened to me recently so I thought I'd update my answer.
For reference there's a sqlite3_api.dll file located in the gem's lib directory. Also the sqlite3.dll file needs to be reachable on the path. They are different files, the first is required by the gem to interface Ruby to C code, while the second contains the actual Sqlite implementation.
It's best to get the second file from the sqlite website and extract it to the Ruby\bin directory (as you shouldn't manually put DLL's into the windows or windows\system directories any more).
So for reference "sqlite3_api.dll" needs to be in:
Ruby\lib\ruby\gems\1.8\gems\sqlite3-ruby-1.2.3-x86-mswin32\lib
and "sqlite3.dll" needs to be on the path, possibly in:
Ruby\bin
As for the "driver not found" problem I would suggest trying the easy things first and making sure gems is installed correctly, up to date, and that the RUBYLIB and PATH environment variables are set appropriately. (System restart may be required to propagate the changes fully.)
Re this link
Download sqlitedll-3_6_10.zip and extract into ruby/bin!
Try going to sqlite.org download page and get the zipped up dll. Then put that in your c:\windows\system32 folder, that should allow Ruby to find it.
Restart your machine after running install sqlite3-ruby
To clarify, which gem are you using? sqlite-ruby or sqlite3-ruby?
They're part of the same project, but different releases. The key is that sqlite3 appears to have driver code included.
I assume you're attempting to use the first, since it's giving me the same error. If so, try switching.
Also.. How literal do you mean by this?
but I have the dll in my %PATH%
PATH=...;C:\sqlite\sqlite3.dll
PATH=...;C:\sqlite
The first will attempt to find C:\sqlite\sqlite3.dll\sqlite3.dll, AFAIK.
I use Ruby 1.8.7 (works with 1.9.1 too)
OS is WindowsXP SP3
Go to
http://www.sqlite.org/download.html
and Download file
sqlitedll-3_7_0_1.zip (265.19 KiB)
and unzip then we will get
sqlite3.dll
Copy sqlite3.dll to your bin folder
as C:\Ruby191\bin or C:\Ruby187\bin
then it works

cannot install ruby gems - zlib error

I'm trying to install some Ruby Gems so I can use Ruby to notify me when I get twitter messages. However, after doing a gem update --system, I now get a zlib error every time I try and do a gem install of anything. below is the console output I get when trying to install ruby gems. (along with the output from gem environment).
C:\data\ruby>gem install twitter

Found it! I had the same problem on windows (it appeared suddenly without me doing an update, but whatever):
It has something to do with multiple conflicting zlib versions (I think).
In ruby/lib/ruby/1.8/i386-msvcrt, make sure that there exists a zlib.so file. In my case, it was already there. If not, you may try to install ruby-zlib.
Then go to ruby/lib/ruby/site_ruby/1.8./i386-msvcrt and delete the zlib.so file there.
In ruby/bin, there should be a zlib1.dll. For some reason my Ruby version did not use this dll. I downloaded the most recent version (1.2.3) and installed it there. I had to rename it to zlib.dll for it to be used.
And tada! Rubygems worked again.
Hope this helps.
Firstly, I thank the person, who came up with the solution to the missing zlib problem. (It wasn't me. :-)
Unfortunately I lost the link to the original posting, but the essence of the solution on Linux is to compile the Ruby while zlib header files are available to the Ruby configure script. On Debian it means that zlib development packages have to be installed before one starts to compile the Ruby.
The rest of my text here does not contain anything new and it is encouraged to omit it, if You feel comfortable at customizing Your execution environment at UNIX-like operating systems. The following is a combination of a brief intro to some basics and step by step instructions.
------The-start-of-the-HOW-TO-------------------------
If one wants to execute a program, let's say, irb, from a console, then the file named irb is searched from folders in an order that is described by an environment variable called PATH. It's possible to see the value of the PATH by typing to a bash shell (and pressing Enter key):
echo $PATH
For example, if there are 2 versions of irb in the system, one installed by the "official" package management system, let's say, yum or apt-get, to /usr/bin/irb and the other one that is compiled by the user named scoobydoo and resides in /home/scoobydoo/ourcompiledruby/bin then the question arises, which one of the two irb-s gets executed.
If one writes to the
/home/scoobydoo/.bashrc
a line like:
export PATH="/home/scoobydoo/ourcompiledruby/bin:/usr/bin"
and restarts the bash shell by closing the terminal window and opening a new one, then by typing irb to the console, the
/home/scoobydoo/ourcompiledruby/bin/irb gets executed. If one wrote
export PATH="/usr/bin:/home/scoobydoo/ourcompiledruby/bin"
to the
/home/scoobydoo/.bashrc
,then the /usr/bin/irb would get executed.
In practice one wants to write
export PATH="/home/scoobydoo/ourcompiledruby/bin:$PATH"
because this prepends all of the values that the PATH had prior to this assignment to the /home/scoobydoo/ourcompiledruby/bin. Otherwise there will be problems, because not all common tools reside in the /usr/bin and one probably wants to have multiple custom-built applications in use.
The same logic applies to libraries, except that the name of the environment variable is LD_LIBRARY_PATH
The use of the LD_LIBRARY_PATH and PATH allow ordinary users, who do not have root access or who want to experiment with not-that-trusted software, to build them and use them without needing any root privileges.
The rest of this mini-how-to assumes that we'll be building our own version of ruby and use our own version of it almost regardless of what is installed on the system by the distribution's official package management software.
1)=============================
First, one creates a few folders and set the environment variables, so that the folders are "useful".
mkdir /home/scoobydoo/ourcompiledruby
mkdir -p /home/scoobydoo/lib/our_gems
One adds the following 2 lines to the
/home/scoobydoo/.bashrc
export PATH="/home/scoobydoo/ourcompiledruby/bin:$PATH"
export GEM_HOME="/home/scoobydoo/lib/our_gems"
Restart the bash shell by closing the current terminal window and opening a new one or by typing
bash
on the command line of the currently open window.
The changes to the /home/scoobydoo/.bashrc do not have any effect on terminal windows/sessions that were started prior to the saving of the modified version of the /home/scoobydoo/.bashrc
The idea is that the /home/scoobydoo/.bashrc is executed automatically at the start of a session, even if one logs on over ssh.
2)=============================
Now one makes sure that the zlib development packages are available on the system. As of April 2011 I haven't sorted the details of it out, but
apt-get install zlibc zlib1g-dev zlib1g
seems to be sufficient on a Debian system. The idea is that both, the library file and header files, are available in the system's "official" search path. Usually apt-get and alike place the header files to the /usr/include and library files to the /usr/lib
3)=============================
Download and unpack the source tar.gz from the http://www.ruby-lang.org
./configure --prefix=/home/scoobydoo/ourcompiledruby
make
make install
4)=============================
If a console command like
which ruby
prints to the console
/home/scoobydoo/ourcompiledruby/bin/ruby
then the newly compiled version is the one that gets executed on the command
ruby --help
5)=============================
The rest of the programs, gem, irb, etc., can be properly executed by using commands like:
ruby `which gem` install rake
ruby `which irb`
It shouldn't be like that but as of April 2011 I haven't figured out any more elegant ways of doing it. If the
ruby `which gem` install rake
gives the zlib missing error again, then one should just try to figure out, how to make the zlib include files and library available to the Ruby configure script and recompile. (Sorry, currently I don't have a better solution to offer.)
May be a dirty solution might be to add the following lines to the
/home/scoobydoo/.bashrc
alias gem="`which ruby` `which gem` "
alias irb="`which ruby` `which irb` "
Actually, I usually use
alias irb="`which ruby` -KU "
but the gem should be executed without giving the ruby the "-KU" args, because otherwise there will be errors.
------The-end-of-the-HOW-TO------------------------
I just started getting this tonight as well. Googling turned up a bunch of suggestions that didn't deliver results
gem update --system
and some paste in code from jamis that is supposed to replace a function in package.rb but the original it is supposed to replace is nowhere to be found.
Reinstalling rubygems didn't help. I'm reinstalling ruby right now.........and it is fixed. Pain though.
How about cd into rubysrc/ext/zlib, then ruby extendconf.rb, then make, make install.
After do that, reinstall ruby.
I did this on ubuntu 10.04 and was successful.
A reinstall of Ruby sorted this issue out. It's not what I wanted; I wanted to know why I was getting the issue, but it's all sorted out.
It most often shows up when your download failed -- i.e. you have a corrupt gem, due to network timeout, faulty manual download, or whatever. Just try again, or download gems manually and point gem at the files.
if gem update --system not works and rename ruby/bin/zlib1.dll to zlib.dll not helps try:
Open file RUBY_DIR\lib\ruby\site_ruby\1.8\rubygems.rb
And replace existed def self.gunzip(data) by this:
def self.gunzip(data)
require 'stringio'
require 'zlib'
data = StringIO.new data
# Zlib::GzipReader.new(data).read
data.read(10) # skip the gzip header
zis = Zlib::Inflate.new(-Zlib::MAX_WBITS)
is = StringIO.new(zis.inflate(data.read))
end
Try updating ZLib before you do anything else. I had a similar problem on OS X and updating Compress::Zlib (a Perl interface to ZLib) cured it - so I think an old version of ZLib (is now 1.2.3) may be where your problem lies...
install pure ruby zlib if all else fails
