'require'：没有要加载的文件— rails / cli（LoadError）

Question

when I uninstalled bundler 1.6.2 to use 1.0.0 rails crashed. I tried this command:

gem uninstall -i /home/mayukh/.rvm/gems/ruby-1.9.2-p320@global bundler -v=1.6.2

Please note, I have uninstalled this globally

Now, when I run rails -v or rails s it shows error like this:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- rails/cli (LoadError)
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from /usr/bin/rails:7:in `<main>'

My ruby version is ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]

1. Is it the right way to use/uninstall bundler? or is there any way to switch between bundlers?
2. How to fix this issue and run rails again?

Answer 1

Uninstall bundle might not be the better solution. If you want to force the bundle version to install something try this (as said in this post ) :

bundle _1.0.0_ install

But for you current problem, you should do what tadman said. Uninstall all bundle instances and get the lastest one to force the version after.

Hope this help !
