problem in bundler

I already gem bundler in system开发者_运维问答. I check "gem list". it show:

*** LOCAL GEMS ***
bundler (1.0.3)

but I go to app and execute "bundle install". it is show:

bundle: command not found

please help me.

maybe you have not set your gem_home path in your shell variable $PATH...

Try (with your own correct path) in your shell:

export PATH=$PATH:/var/lib/gems/1.8/bin

Maybe this helps you further: How do I use gems with Ubuntu?
