I followed every step described in Redmine installation page and in this article.
I put the following path in environment.rb:
ENV['GEM_PATH'] = '/home/myusername/ruby/gems/gems:/usr/lib64/ruby/gems/1.8'
I tried the following path too:
ENV['GEM_PATH'] = '/home/myusername/ruby/gems:/usr/lib64/ruby/gems/1.8'
Still there is an error when I'm trying to execute the command
RAILS_ENV=production rake config/initializers/session_store.rb
Error message is the following:
Missing the i18n 0.4.2 gem. Please `gem install -v=0.4.2 i18n`
Although gem is there with the specific verison.
Any idea?
try with this
export GEM_HOME=$HOME/ruby/gems/
Bye.
did you set those environment variables and install the gems there, I assume?

I'm developing a couple of private gems and I think I don't understand correctly the PATH/GEM_PATH and/or Bundler/RVM installation flow, would love if someone could chip in.
I have a repository with two gems (A & B for simplicity sake). I've developed the gems using the scaffolding + following the guidelines provided by this bundler tutorial.
Thanks to the Bundler project I have a few Rakefile tasks like rake build, rake install, rake install:local and rake release. Because of the private nature of these gems I can't release them to RubyGems (and we haven't looked into hosting our rubygems).
My machines are using RVM to manage ruby versions and Bundler version 1.15.1
What I want to do: Assuming a new machine/developer trying out the project, ideally we would cd into each of the subfolders (currently 2, gem A and gem B), run rake install and after that we should have the gems available system wide for the current user.
What is happening: The gems are built and work properly, but they are only available inside the subfolder of each gem i.e. gem A is only available inside the subfolder A and gem B is only available inside subfolder B.
What I've tried: So, after rake build/install/install:local a new .gem file is generated under pkg. I've tried to manually install the "compiled" file using gem install pkg/A.gem, gem install --local pkg/A.gem and gem install --local --user-install pkg/A.gem without success. (there are plenty of SO questions/answers about this)
I believe this has something to do with the PATH variables, but like I said before I don't fully understand the way they are managed. I get the following results from these commands:
# Our gem
> gem which A
/home/ubuntu/.rvm/gems/ruby-2.4.0/gems/A-0.1.8/lib/A.rb
# Pry, available globally
> gem which pry
/home/ubuntu/.rvm/gems/ruby-2.4.0/gems/pry-0.11.1/lib/pry.rb
I've been lost and frustrated for far too long now, any help is appreciated. Also open to hear suggestions of better private gem installation flows :)
Yes, it has something to do with your PATH variables. Your installation seems to be good.
I advise you to first affirm your gems installation path with:
echo $GEM_HOME
The double check your PATH to ensure its present and also confirm that the GEM home is also where the gem got installed into from the rake install
echo $PATH
If not, put it in your path and you should be fine with something like this:
echo PATH=$PATH:$GEM_HOME >> ~/.bashrc
source ~/.bashrc
Build your gem as per that guide you linked. You should end up with a gem file. Distribute this as you see fit (I use rsync/crontab to download newer gem versions but anything goes). User can install the gem as follows:
gem install --user-install /path/to/your/file.gem
This will install the gem in the user's ~/.gem/ruby/<version>/gems/<your-gem-name> directory.
Tried it with an empty gem (foodie, as in that example guide) and it works fine. But if you don't specify the --user-install parameter it will try to install in the system ruby dir (/usr/lib/ruby/gems...)
I am trying to include the ruby-mysql gem in my ruby script. I have installed the gem using bundler but when I run bundle exec ./mysql_connector, I receive the error ./mysql_connector:4:in ``require': cannot load such file -- ruby-mysql (LoadError). Can you please help me troubleshoot what the problem is?
What I did
Installed rails in my home directory.
I do not have root access to the server so I have installed rails in my local directory by following the instructions here:
http://www.r-bloggers.com/installing-ruby-on-linux-as-a-user-other-than-root/
Created a directory for my application.
My application resides in my home directory in a folder called connector. It has a Gemfile that looks like this:
source 'https://rubygems.org'
gem 'ruby-mysql'
Call bundle install.
Using ruby-mysql 2.9.14
Using bundler 1.11.2
Bundle complete! 1 Gemfile dependency, 2 gems now installed.
Bundled gems are installed into ./vendor/bundle.
Add dependencies to my script. My script is in connector/mysql_connector and it reads:
#!/home/dcox/bin/ruby
require 'rubygems'
require 'bundler/setup'
require 'ruby-mysql'
Make script executable. I saw that you need to run bundle exec using an executable file, so I followed the instructions here to make my script executable: http://commandercoriander.net/blog/2013/02/16/making-a-ruby-script-executable/
Run the script. I execute using bundle exec mysql_connector and see:
/home/dcox/bin/mysql_connector:4:in `require': cannot load such file -- ruby-mysql (LoadError)
from /home/dcox/bin/mysql_connector:4:in `<main>'
Is it the $LOAD_PATH? After searching around for answers, I discovered a lot of SO answers as well as a blog post (https://codedecoder.wordpress.com/2013/09/23/require-and-load-in-ruby-loaderror-cannot-load-such-file/) that seem to suggest the problem is that the gem is not installed in a directory on the $LOAD_PATH. Here is what I see when I run $LOAD_PATH from IRB:
irb(main):002:0> $LOAD_PATH
=> ["/home/dcox/lib/ruby/site_ruby/2.1.0",
"/home/dcox/lib/ruby/site_ruby/2.1.0/x86_64-linux",
"/home/dcox/lib/ruby/site_ruby", "/home/dcox/lib/ruby/vendor_ruby/2.1.0",
"/home/dcox/lib/ruby/vendor_ruby/2.1.0/x86_64-linux",
"/home/dcox/lib/ruby/vendor_ruby", "/home/dcox/lib/ruby/2.1.0",
"/home/dcox/lib/ruby/2.1.0/x86_64-linux"]
Next I checked to see the location of ruby-mysql:
dcox#analytics1:~/connector$ bundle show ruby-mysql
/data/home/dcox/connector/vendor/bundle/ruby/2.1.0/gems/ruby-mysql-2.9.14
Obviously my connector/vendor/bundle path is not on the $LOAD_PATH. I could add it, but I have a feeling I am missing something simple here because bundler is supposed to work as long as you follow the instructions, right?
Any advice or help is very much appreciated! Thanks!!
If you just want to require this specific gem, require 'mysql' should work (e.g., https://github.com/tmtm/ruby-mysql/blob/master/test/test_mysql.rb#L10).
Your file should call Bundler.setup http://bundler.io/bundler_setup.html
Better yet, if you instead call Bundler.require(:default) it will setup and require all the gems in your Gemfile for you.
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'd like to install the scheduler_daemon plugin. I get to this part of the instructions and I'm stuck.
script/plugin install git://github.com/ssoroka/scheduler_daemon.git
# Install required gems
gem install daemons rufus-scheduler eventmachine chronic -s http://gemcutter.org
Error:
The term 'script/plugin' is not recognized as the name of a cmdlet, function...
Ok, so I preface it with Ruby:
PS>ruby script/plugin install git://github.com/ssoroka/scheduler_daemon.git
D:\Ruby193\bin\ruby.exe: No such file or directory -- script/plugin (LoadError)
I then tried ruby script/plugin install calendar_helper but got the same error. I tried putting script/plugin in quotes. I tried putting a trailing slash. I tried using http://github.... There are other things I've tried, to no avail.
What do I need to do to install a Ruby plugin via Powershell?
Found it shortly after: rails plugin install git://github.com/ssoroka/scheduler_daemon.git
The thing I've learned about Rails: any info that isn't on an official Rails site may be very outdated. Go to http://guides.rubyonrails.org/ first, second, then stackoverflow, then the rest of the net.
Before Rails 3
ruby script/plugin install git://github.com/ssoroka/scheduler_daemon.git
should work, provided you are at the root of your Rails app.
From Rails 3 onwards, this has become rails plugin install
we tried to install rake on our pc but there were following errors.. We even tried updating gems but in vain. We need to run some tasks on rake and dont know how to go abt it.

Are you behind a proxy server? If so, set your HTTP_PROXY environment variable appropriately. This is the sort of error you get when the repository can't be contacted. For example:
set HTTP_PROXY=http://proxy.mycompany.com:8888
will set it temporarily.
I don't think that's the command to update RubyGems. Have you tried gem update --system? You might be able to install Rake after that.
