I am developing a Sencha touch 2 application. I have been following the "Styling the user interface of a Sencha Touch application" tutorial on theming of secha touch applications.
It requires me to install Ruby, Compass and SASS.
I installed Ruby using the installer from rubyinstaller.org.
On executing the following command, I get the expected result which confirms correct installation:
C:\>ruby -v
ruby 1.9.3p327 (2012-11-10) [i386-mingw32]
Current source is up to date:
C:\>gem sources
** CURRENT SOURCES **
http://rubygems.org/
Next, since I am behind a proxy, I used the following command to install HAML/Compass:
C:\>gem install -p [proxy:port] compass
ERROR: While executing gem ... (Zlib::GzipFile::Error)
not in gzip format**
Can someone help me? I found solutions such as system update, gem sources update, but everything is up to date on my system.
Edit:
C:\>gem install compass
works perfectly fine on my private system. When I try the same command from my workplace I need to use the proxy as mentioned above and that results in an error.
I assume the ERROR occurs since the web sense at my workplace blocks these downloads.
Solution: I downloaded the required gems: chunky_png, fssm, compass, sass, haml etc.. directly from http://rubygems.org/gems and placed these gems in my local directory.
After this I tried gem install compass. This first searches your local directory. On finding the required gems, installation takes place. Does not require connection to the ruby website.
Note: Run the command from the path where the gems are located
eg: I have placed the gems in C:\Ruby193\lib\ruby\gems\1.9.1\gems
So I run the following command :
C:\Ruby193\lib\ruby\gems\1.9.1\gems>gem install compass
I had a similar problem, it worked on my own private laptop, but failed while using a virtual server at work (running Ubuntu 12.10) that used a proxy.
Following the suggestion I found here, from the command line I defined:
export HTTPS_PROXY=proxy-address:proxy-port-number
export HTTP_PROXY=proxy-address:proxy-port-number
and then my gem install package worked fine.

I'm trying to install middleman. I installed the gem and can see it in my gem list. However, if I enter middleman -v I get the message middleman: command not found.
I tried installing bundler to run middleman with a Gemfile in the project directory using bundle exec middleman. But when I try to run bundle I get the following error:
bash: /usr/bin/bundle: /usr/bin/ruby: bad interpreter: No such file or directory
I'm running ruby v. 2.6 and installed middleman v.4.3.5 on Ubuntu 18.04.
Any help would be very much appreciated; I've wasted half a day trying to solve this and I'm still on high waters!
which ruby gives me /snap/bin/ruby and my path variable is /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/share/rvm/bin. The problem is that ruby is in the snap folder.
I just uninstalled the ruby snap (and snaps in general) and installed "normal" Ruby, which had the correct path (usr/bin/ruby). The middleman installation then worked fine.
I work inside a corporate firewall. I am using Windows 10 and have the Ruby 2.4 x64 install.
I need to get the sass gem. I cannot do it through the command line because all external calls such as this are blocked and will not be unblocked for my situation. Is there a place I can manually download the sass gem, and then issue the command to install the gem from a local file?
I'm in the same position and use two techniques
through the firewall
See my answer at installing-gems-from-behind-a-corporate-firewall
from a local file
You download the gem from https://rubygems.org/downloads/sass-3.5.4.gem
You can put the file in your ruby\bin folder and delete it later.
Then you cd to your bin folder and install it in the console with the command
gem install sass-3.5.4.gem --local
the 3.5.4 is the current version.
If there are dependencies (other gems) you need to first download them as wel.
Can't see what these are because on this machine I'm still using Ruby MRI 1.9.3 and the current version of sass requires Ruby 2.0.0

We are working on Predix Mobile SDK.So we are try to set Predix Mobile Development Environment for that we need set UAAC command line-utility .We flowed this link (https://github.com/cloudfoundry/cf-uaac).
For Install we tried like this
gem install cf-uaac
We got error this
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.
after that we google about this error but we got nothing .Please guide to us for UAAC CLI.
The cloud foundry cf-uaac cli tool is written in Ruby, so installation is done with gem, the ruby package manager.
You can run gem env from a terminal to find the installation directory for gems which is probably /usr/bin in your case. You wouldn't want to install your gems there as only root has permission to write. If you are on OSX there may even be more to the story.
I'm not sure what OS you are using so can't be too prescriptive, but a few suggestions for you can be found in this previous question to override this default behavior on your system:
Override install location on the commandline --user-install cf-uaac
Edit your ~/.gemrc to include something like this or change to one of the GEM PATHS
Re-install ruby to a different location where you do have write permission
Use ruby version manager rvm if you will be doing lots of ruby dev work and want to switch versions / gems
You can find out lots more about the install command in the rubygems guide if you were interested in learning more.
Hope that gets you going again.
UAAC is the Ruby-based command line interface (CLI) for interacting with the Cloud Foundry User Account and Authentication (UAA)
first install Ruby, you can follow the guidelines (steps 1 & 2) from here:
Ruby for Windows
then run this commend from powershell:
gem install cf-uaac
If you are behind a proxy you should add the source:
gem sources -a http://rubygems.org
I'm a newbie to programming, with ruby/rails successfully installed on my (mac) home computer. I'm trying to get ruby 2.0.0p195 (and Rails) set up on Windows at work (Windows 7, 32bit) and I'm failing on the sqlite3 installation. I've been through most of the solutions/suggestions I can find on the web, but just can't get it to work - the frustrating thing is that it tells me it's installed, but it doesn't work:
- I've tried the knapsack installation http://www.ruby-forum.com/topic/4413168
- If I try to install --with-opt-dir=c:/sqlite3 (or any of the many variations suggested) it gives a native extension error.
- I've put the .dll file in Ruby/bin, which is also in my PATH
- I have the devkit installed
The 'gem install sqlite3' command is successful, and if I do 'gem list', sqlite3 v1.3.7 x86-mingw32 appears in the list, but if I 'require sqlite3' in IRB I get:
LoadError: cannot load such file -- sqlite3/sqlite3_native
And the mkmf log says:
find_header: checking for sqlite3.h... -------------------- no
But I've confirmed the sqlite3.h file (and the sqlite3.c, sqlite3.o, and sqlite3.h files) is in my c:\sqlite3 directory, and as noted above, I've also tried installing '--with-opt-dir'.
So next I trace the error when I 'require' sqlite to a file '\kernel_require.rb' in ruby/lib, and it references to this:
if Gem::Specification.unresolved_deps.empty? then
return gem_original_require(path)
end
I'm lost, and WAY out of my depth. At this point my only solution would be either to completely uninstall and start again, or to downgrade to ruby 1.9.x, but others seem to have sqlite3 and ruby 2.0 working so it's obviously (?) semi-stable. Help?
UPDATE: I've now tried downgrading to ruby 1.9.3, and apart from pik reverting to the most recent version of ruby every time I shut the command line, I can actually get the server to run etc. So it seems this issue is related specifically to ruby 2.0.
I am encountering the same issue, except that I don't really think that it is related to Ruby 2, but to rails 4 instead.
I have managed to install the sqlite3 gem by downloading the source, dll and exec (dll and executables need to be added to PATH accessible) and installying the gem with the follwing process:
Download:
http://www.sqlite.org/2013/sqlite-amalgamation-3071700.zip
http://www.sqlite.org/2013/sqlite-dll-win32-x86-3071700.zip
Extract and put the files in a location on your C drive or wherever you want. Then copy sqlite.dll and sqlite.def to the Ruby/bin directory.
Then you go to the DevKit directory and run msys.bat, in which you issue the following command:
gem install sqlite3 --platform=ruby -- --with-sqlite3-dir=path-to-sqlite --with-sqlite3-include=path-to-sqlite
This allowed me to install the gem successfully (using Ruby-2.0.0-p247 x86 and devkit). I validated through irb doing:
require 'sqlite3'
SQLite3::SQLITE_VERSION
I'm still trying to figure out this issue.
I get the same error message when I try to start the server or whenever I try to run the rails console.
I'd love to get this issue fixed...
I have installed Ruby on my system, and now I want to install Compass. But when I execute the gem install compass command, it shows an error like this:
could not find valid gem 'compass' <>=0> in any repositary
And also:
SocketError: getadressinfo: no such host is known.<http://rubygems.org/latest_specs.4.8.gz>
I don't know what the problem is. If I run ruby -v, it shows the Ruby version. So what's the problem with installing Compass?
Can anyone explain this to me properly? I've searched Google, but all I could find was some proxy problem - and I couldn't understand how to set the proxy at all.
I'm using Windows and a company internet connection, so I don't know the username and password of my proxy.
I was behind a proxy and HumberFrench's solution above helped:
Go to Ruby bin folder:
cd c:/Ruby193/bin
And then install compass gem:
gem install compass --http-proxy http://<proxy_adreess>:<port_of_proxy>
Another tip: am on Aptana Studio, so this could be run from within Aptana's terminal.
Cant up-vote so adding this here.
I had the same problem, finally solved it manually.
Goto the rubygems compass page, and download the gem by clicking the Download link. Scroll down and you will see three Runtime Dependencies. Goto each of them and download those gems also. Put all of them in a directory, and try
gem install downloaded_compass_filename
This should solve your problem.
If it gives an repository not found error message, you can force gem to try local files through the gem --local install option
if you use a proxy, and get error, do it
gem install compass --http-proxy http://<proxy_adreess>:<port_of_proxy>
gem install -h gives you a lor of options
The proxy is the most likely cause. You will have to get permission from the network admin, or manually download compass. For more info, See this SA post.
If you decide to go the manual route here is a link to the RubyGems compass page. This not ideal, but also better than having to write css without compass magic ^^
Good luck!
On windows i had a few instalations of ruby:
C:\ruby187
and
C:\Ruby200-x64
install compass in both places, using:
gem install compass
Try running the install command in the bin folder.
$ cd C:\Your_Ruby_Folder\bin
$ gem install compass
I have same problem and i resolve it with.
Uninstall ruby end deleted folder ruby
Download ruby version 1.9.x
After thet install sass
last stem: install compass
