Could not find rails (>= 0) amongst [] (Gem::LoadError)
Solution 1
I had to sudo gem install bundler
to make it work again.
Solution 2
I've had a similiar problem. Not sure if that helps you, but you might try to install gems with rvmsudo gem install [gemname]
instead of just doing gem install [gemname]
or sudo gem install [gemname]
.
I try to explain this a bit because of the upvotes:
This basically is a path issue. If you set up gems via gem install
, they mostly likely will be in another directory (e.g. /usr/local/
) compared to gems set up via bundler (where you can override it with --path
). Using sudo
may also set them up into another directory since sudo
starts a subshell which has a different environment then. This is why you have rvmsudo
.
If you want to see the differences, compare $PATH
, $GEM_HOME
, $GEM_PATH
and $BUNDLE_PATH
when echoing directly, with sudo
and with rvmsudo
.

I got a problem similar to this, there may be a compatible problem of rvm. I fixed by updating rvm to latest version:
curl -L https://get.rvm.io | bash -s stable --ruby
Then you should reload rvm or just open new terminal window. Then I reinstalled the bundler 'gem install bundler' and ran 'bundle install' as normal
Solution 4
rvm rubygems current
did the trick for me.
Solution 5
remove ruby first then
sudo apt-get install build-essential libssl-dev libreadline5 libreadline5-dev zlib1g zlib1g-dev
to install all needed lib then you could install ruby and rails
rvm install 1.9.3
rvm --default use 1.9.3
rvm gem install rails

After installing rvm, updating .gmrc file, updating rubygems and running
gem install rails -v ">=3.1.0rc"
, I now seem to have a complete mess:$ rails -v /usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:247:in `to_specs': Could not find rails (>= 0) amongst [] (Gem::LoadError) from /usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:256:in `to_spec' from /usr/local/lib/site_ruby/1.8/rubygems.rb:1182:in `gem' from /var/lib/gems/1.8/bin/rails:18

jmervine over 11 yearsIf you already have rvm installed and a newer version, this should do the same thing:
rvm get stable --auto

Shaker Ahamed over 9 yearsi have this issue when creating my own gems and still developing them. In the main app i use path to reference the folder. when outside the application directory and I want to do something like rails -v I get this error saying it cannot find a custom gem I am developing. Any recommendations on a potential fix?
