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

I recently upgraded my distro (Ubuntu from 16.04 to 18.04), and I guess either on the upgrade or on the regular sudo update/upgrade calls gem was upgraded and I currently have the 2.7.6 version. I barely use Ruby lately, but just now I had to run a jekyll/bundle command which returned me that it had a bad interpreter (it was looking for ruby2.3 and it's currently installed on the 2.5 version).
My next step would be updating the jekyll and bundle gems (so they update the interpreter version), but to my surprise they aren't listed when I run gem list. They were obviously installed since there's a /usr/local/bin/jekyll executable and a /usr/local/bin/bundle one as well. But I think when gem was upgraded it started checking gems on a different folder (/var/lib/gems/2.5.0 I'm guessing) but jekyll/bundle apparently are in /var/lib/gems/2.3.0. I'd be fine just installing jekyll/bundle on the 2.5.0 version, but is there a way to remove all gem files from the older version since they are useless now?
I highly recommend you to use a ruby version manager like rvm or rbenv to manage different ruby versions installed on your system.
If you just want to remove the gems from your disk, you can find the location of each gem with the command bundle show $gem_name and delete the parent directory to delete all of them. You may need to delete the Gemfile.lock as well to reset the locked gem versions.
Here's what I recommend:
Use rbenv for multiple Ruby version management, no customizations needed
a ruby installer plugin is now included with rbenv
it also handles ruby executable shims automatically, don't need to rbenv rehash anymore
it loads really fast (rvm has a noticable load time on shell startup)
Use bundler to dynamically resolve gems at runtime (options below)
it's fast enough anyways
don't need a special gem solution, bundler comes included /w Ruby now
Options to invoke bundler dynamically (I recommend the last one):
use bundle exec in front of every ruby executable
variant: create alias be='bundle exec'
create bundle binstubs <LIST GEM EXECUTABLES YOU WANT> for each project
use bin/ in front of every ruby executable to call the binstubs
do #2 and then set up .git/safe
lets you manually allow PATH lookups to the bin/ folder while in that project root
don't need to type bin/ anymore
Now multiple gem versions will all be installed into the same Ruby version bucket, and you let bundler dynamically add the right versions to the load path before every startup.
Removing a Ruby version will also mean removing all the gems (and versions of those gems) installed for that Ruby version as well.
I'd like to thank both answers. I upvoted them because even though they're not a direct solution to my problem they give good directions to prevent it.
NOTE: These are the steps I took, which doesn't mean they are the correct way, so don't take more as a reference than a guide.
Here's what I did to clean up those old Ruby version gems:
First I needed to add an environment variable for gem to be able to find those obsolete gems, by running GEM_PATH=/var/lib/gems/2.3.0.
Then it's possible to get the contents and specification of the gems with gem contents name_of_gem and gem specification name_of_gem.
I individually uninstalled those gems that were obsolete with sudo GEM_PATH=/var/lib/gems/2.3.0 gem uninstall -i /var/lib/gems/2.3.0 name_of_gem. In my case I did a sudo install, so I needed sudo which also required me to set the environment variable again because of sudo's security policy. Also, I needed to manually set the install directory for some reason.
Some gems will have executables, and the uninstall will ask if you want to remove it. I wasn't able to get the gem uninstall to remove it because it claimed I didn't have write permission to /var/lib/gems/2.3.0/bin (which is weird because the EXECUTABLE DIRECTORY gem environment variable was /usr/local/bin). I asked gem not to remove the executables, wrote down their names and removed them manually from the EXECUTABLE DIRECTORY folder. You can also use which gem_executable_name to find out where it's located.
After uninstalling all the gems I believe it's safe to remove the /var/lib/gems/2.3.0 folder and its contents. Running gem contents on all of them only returned me files on this folder so I believe the only external files were the script/executables that were added to /usr/local/bin.
I am using overcommit gem (https://github.com/brigade/overcommit) in my project, when I use Github Desktop for osx I get these errors:
This repository contains hooks installed by Overcommit, but the
overcommit gem is not installed. Install it with gem install
overcommit. (1)
The gem is installed, it works in terminal. I guess it's because I use rvm and Github Desktop doesn't know about rvm. Anybody knows how to fix this?
Ok finally got it to work!
Combined the answer from #michelegera with comment from #rewritten
Step 1:
sudo su -
gem install bundler
gem install overcommit
gem install rubocop
Step 2: added command: ['bundle', 'exec', 'rubocop'] to .overcommit.yml
Thanks for the help!
Most likely it's this line where the error occurs. As you can see the main issue is that it's not able to require 'overcommit'. I don't know the GitHub desktop client so well (maybe there is a way to configure it inside of it), but one thing you could do is adding the absolute path where rvm stores your gems to the "require path" in the hook file. This could look like:
$: << "/home/user/.rvm/path/to/gems/dir"
The disadvantage of this is that you would have your absolute path in the hook file and it most likely won't work for others. You might also want to consider installing the gem globally for the the ruby interpreter that executes the script (see Shebang line in the hook file).
You are right, Github Desktop (or any other GUI) isn’t running in your terminal environment, so it knows nothing about your specific RVM installation.
A simple solution is to install overcommit and any other gems required by your hooks into your system Ruby:
sudo su -
gem install bundler
gem install overcommit
gem install rubocop
...
If you installed Git via Homebrew or other means, you might have to change the Git binary used by your GUI.
For example, in Tower, I selected Homebrew’s version rather than the System’s.
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
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 typed following command in prompt:
# gem install vim-ruby --remote
then got a error message:
ERROR: Could not find a valid gem 'vim-ruby' (>= 0) in any repository
My environment is windows xp and ruby's version is 1.9.3
how to solve it?
vim-ruby is not a gem. Checking the gem repository using gem list vim -r returns several gems, but not that one.
From the docs:
How you get these files into Vim:
[...]
By downloading one of the tarballs, you can easily install the latest
stable or development version wherever you like on your machine. No
README, no vim-ruby-install.rb, just Vim files. You would typically
install these into either $VIM/vimfiles, for system-wide use, or $HOME/.vim
($HOME/vimfiles on Windows) for personal use.
Remember that when you install Vim in the first place, all of these files
are present. The purpose of downloading and installing them from
github is to get the latest version of them.
vim-ruby is not a gem but the page: https://github.com/vim-ruby/vim-ruby has a link https://github.com/vim-ruby/vim-ruby/wiki in which the link "VimRubySupport" has a section "Installing the latest version" which shows the vim-ruby as a gem. I too had the same problem as the original post. I downloaded the archive file from http://rubyforge.org/projects/vim-ruby/ which has a .rb file (bin/vim-ruby-install.rb after untarring the archive in my case) which installs the required vim files.
This method should solve your issue:
$ gem install --http-proxy http://201.187.107.19:8080 vim-ruby
Note, the IP address and the port number refers to a proxy. You should search for a proxy list and use one of the proxies there.
