I am unable to install Rails on Cloud9 IDE

Question

I am getting the following error using ruby 1.9.3

gem install rails --version=4.0.0 /opt/rh/ruby193/root/usr/share/rubygems/rubygems/specification.rb:541:in `read': Permission denied - /usr/libexec/openshift/cartridges/c9-0.1/root/lib/ruby/gems/specifications/multi_json-1.8.4.gemspec (Errno::EACCES)

Answer 1

This is what I got from support:

"That is indeed a deployment regression that went with our latest release that's causing this issue and break new workspace creations. We have a fix for it that should be in production in 12 hours from now.

However, a workaround would be to separate your ruby workspace's environment from our shared space installation:

edit ~/.bashrc adding the line to the end of the file (using nano or vim):

export GEM_PATH=$HOME/lib/ruby/gems

Then:

$ source ~/.bashrc

$ gem install rails -v 3.2.16

$ bundle install
