Ohai fails to determine os_version in cygwin - windows

I'm trying to run ohai.bat os_version within cygwin on Windows Server 2003 R2, and it returns an empty array as output. If I instead run ohai os_version in cmd.exe, then it correctly returns:
[
"5.2.3790"
]
Given that ohai.bat os_version works on another one of my virtual machines, I'm inclined to believe that this is an environment misconfiguration of some form. Does anyone have any ideas on what to check?

It turns out that the problem is caused by systemu not properly quoting directory names. This commit fixes the problem, but is not currently available in any released gem. It will be in version 2.0.0 of systemu. To fix it in your own project for now, you'll need to clone systemu off github and build the gem yourself.

version of Ruby for cucumber

I have no knowledge in Ruby, but I need to run some tests in it. The code is in Ruby and Cucumber. I use intellij on Mac. When I first open intellij cucumber step definition where not recognised from feature file. In terminal I got:
Required ruby-2.1.2 is not installed.
To install do: 'rvm install "ruby-2.1.2"'
but
$ which ruby
/Users/myuser/.rvm/rubies/ruby-2.4.1/bin/ruby
so I run the install command as suggested and now I get
$ which ruby
/Users/myuser/.rvm/rubies/ruby-2.1.2/bin/ruby
Now my feature files connected to step definition as well. I will appreciate if anyone could explain me what happened. What prompted me to downgrade the version of Ruby and how it fixed cucumber.
Make sure you have ruby 2.1.2 set in File -> Settings -> Languages & Frameworks -> Ruby SDK and Gems
What I suspect is happening is you have run rvm use 2.1.2 in the terminal but when your IDE runs something it is using the ruby version set in the settings.
You probably have a .ruby_version file in the project root directory. This will enforce a specific version of Ruby. So the person who put it there is who to ask why the version was restricted like that. There may have been a good reason, such as that's what is being used by all your users.
It has nothing to do with Cucumber. rvm has some kind of operating system hook, I think, that runs whenever you cd into a directory. It looks for its special control fiels such as .ruby_version and .rvmrc file. This page describes this in more detail: https://rvm.io/workflow/projects.

Cannot build JXcore on one of Windows machines

I'm trying to build JXcore on Windows 7 (64 bits).
In fact I have two identical virtual machines, but when i run vcbuild.bat it fails for one of them. I get the following error:
C:\jxcore\vcbuild.bat
File "configure", line 339
'''
^
SyntaxError: Missing parentheses in call to 'print'
Failed to create vc project files.
On the second machine I don't have this problem. As far as I remember, I've created them both identical. Where is the problem then?
Are those two VMs really equal? I can bet, that the one which fails, has Python 3.X installed, while the JXcore docs are stating about Python 2.6 or 2.7.
Nevertheless, we've just made an update, and the error that you've posted should not show up any more. Instead you should see something like this:
C:\jxcore>vcbuild.bat
You need Python 2.6 or 2.7 for the script to run. Currently installed version: 3.4.3
I hope that solves your problem. Thanks for using JXcore!

heroku toolbelt not running on Windows XP

I downloaded the latest toolbelt for Windows; however, when I try to launch any heroku command from DOS I get:
c:/Program Files/Heroku/lib/heroku/updater.rb:126:in fork': fork() function is unimplemented on this machine (NotImplementedError)
from c:/Program Files/Heroku/lib/heroku/updater.rb:126:inbackground_update!'
from c:/Program Files/Heroku/lib/heroku/updater.rb:111:in inject_libpath'
from c:/Program Files/Heroku/bin/heroku:19:in'
My purpose is to deploy a Play! app on heroku. I'm using Windows XP SP3. Anybody to enlighten me because I'm having headache.
I just ran into the same problem. My solution was to comment out the call to fork.
Navigate to your Heroku installation directory, and find the file updater.rb in the subdirectory lib\heroku.
Comment out lines 126 (should be pid = fork do), 143 (end) and 144 (Process.detach.pid).
That should do the trick.
In your home directory (i.e. C:/Users/xxx/.heroku/autoupdate.last) create a file called "autoupdate.last".
See updater.rb:
File.join(Heroku::Helpers.home_directory, ".heroku", "autoupdate.last")
I have a co-worker on Windows 7 who had this problem. He accidentally installed ruby 1.8.7. This error seems to occur when you are using ruby 1.8.7 with a current version of the Heroku Toolbelt (2.32.9 at this writing). Heroku Toolbelt seems to prefer Ruby 1.9.x. You can run gem install heroku, and the error goes away, but you will get warnings about the heroku gem being deprecated which means it will probably be missing current features. Update to ruby 1.9.x if you can. While valid in some cases, editing ruby files should be a last resort in my opinion.
I'm not sure which of these fixed issue, but one or both of them did:
1. Deselected "hidden" Users/[user]/.heroku" folder.
2. Deselected "read" only for folder.

Error with Compass polling on windows 7

I am attempting to work locally on a PHP application which I cloned from the Git repository my partner and I use.
He uses a Mac, and until now I have been working on the app in a virtual Ubuntu Linux environment. Both environments have been able to use Compass polling with the same file structure and files.
On Windows 7, I run Compass commands from Cygwin, and this is the command I use to have Compass poll from the root directory of the app (C:/wamp/www/application):
compass watch --trace src/Application/ApplicationBundle/Resources/compass/
When I then make a change to a .scss file, I receive the following error:
ArgumentError on line 716 of /usr/lib/ruby/1.8/pathname.rb: different prefix: "/

All I've been able to find through searching is that it may have something to do with the fact that Windows capitalizes its drive names, although the lack of slashes in the returned path makes me think the problem may be elsewhere.
Does anyone know why I might receive this error in Windows, but not other platforms?
NOTE: I have found a work-around involving installing ruby (and compass) through Windows' command prompt rather than Cygwin, and that should work fine for now. Still, if anyone has ideas, I'm still curious as to what the problem could be.
According to this commit, this is a problem caused by a compass dependency called FSSM. It is used to monitor file changes in compass. A workaround is described in this comment.
It seems that FSSM detects that ruby is running inside a Windows box, and treats paths in the Windows' way (C:\blabla). Commenting out the line 26 of the file <fssm_gem_path>/lib/fssm/pathname.rb makes compass watch work as expected. You can also add
unless path[0, 1] == File::SEPARATOR
to the end of line 26 to make it work.
I thought I'd just provide a little more info to help people find the pathname.rb file.
On the cygwin prompt type:
gem env
This (unsurprisingly) brings up a load of info about your Ruby Gems installtion. Look for the line which specifies the INSTALLATION DIRECTORY. Mine was:
/usr/lib/ruby/gems/1.8
Now in Windows Explorer navigate to this location but substitute "usr" for your cygwin installation directory. Therefore the above path becomes:
C:\cygwin\lib\ruby\gems\1.8
Once in this location drill down until you come across the fssm gem directory.
Within this [fssm] directory go into:
/lib/fssm/
...and there you should find the pathname.rb file.
Edit it as above and all is well. I hope this helps.
See here for a possible fix:
http://rails.webintellix.com/2010/05/27/error-in-ruby-relative_path_from-call-on-windows/
I was running into this same error with a slightly different setup. My project folder was on a network drive (ruby and sass/compass installed locally), and every time I made a change to a .scss file compass watch would crash with similar errors to the OP. I solved the issue by mapping my network drive instead of accessing it directly via the network (right clicked on My Computer and choose map network drive so I could access my remote drive at A:).
Now, instead of doing 'compass watch //SERVERNAME/My_Project' (I'm using Git Bash), I do 'compass watch a/My_Project' and compass stopped crashing.
Hope that helps someone else.
Using Cygwin, re install a compass dev release (such as 0.13+). Works for me with Compass 0.13.alpha.4 (Markab)
To do so:
gem uninstall compass
gem install compass --pre --no-rdoc --no-ri

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
