已安装RVM捆绑器错误：未安装宝石捆绑器，请先运行`gem install bundler`

Question

I get to work with a new project and it's based on ruby 1.8.7, I'm using rvm to manage my ruby versions and I have installed 1.8.7 and 1.9.2.

The thing is when I do:

rvm use 1.8.7 

and try to run:

bundle install

I get:

ERROR: Gem bundler is not installed, run `gem install bundler` first.

I've installed bundler 5 times and even after that it says it's not installed. What can cause this? Bundle even shows up at my gem list.

update from comments:

The ouput of the which ruby && which gem is:

/home/username/.rvm/rubies/ruby-1.8.7-p371/bin/ruby
/home/username/.rvm/bin/gem

Output of "env | grep -iE 'ruby|rvm|gem' | sort":

GEM_HOME=/home/username/.rvm/gems/ruby-1.8.7-p371@global

Unistalled and installed 1.8.7 via RVM ran:

rvm install 1.8.7 --verify-downloads 1

and it worked.

Answer 1

It looks like you're probably running the wrong version of gem . In my RVM setup, using the shell command overrides recommended with RVM ( source "$HOME/.rvm/scripts/rvm" in your .bashrc or .zshrc or another suitable startup file), gem is normally a shell function. It does some RVM magic under the covers and then runs the real gem command. In my case, both ruby and gem run out of the same version directory:

/home/jim/.rvm/rubies/ruby-1.9.3-p327/bin/ruby
/home/jim/.rvm/rubies/ruby-1.9.3-p327/bin/gem

Make sure you're sourcing the RVM startup script.

Your PATH looks ok. Make sure you have a /home/username/.rvm/rubies/ruby-1.8.7-p371/bin/gem command. If not, you may have to reinstall ruby-1.8.7.

Running rvm current will show which Ruby version and gemset are being used. Make sure there's a gem in the path that matches the Ruby version.

Answer 2

rvm install ruby-1.9.2-p320

use this and remember close all terminal and in edit-> profile preferences--> title and command -->> check (Run command as login shell)
