已安装Rails gem，但无法正常工作

Question

I'm using Rails 3.2.13, but I don't know what's wrong with it. For some reasons, every gem I tried installing recently were successfully installed (as the log reads 'Your bundle is complete!')

But the problem comes when I tried using the gems, they don't seem to be available!

some of the gems I tried using: - best_in_place - rails-bootstrap-toggle-buttons and other gems as well.

None of them worked properly, and for instance, the best_in_place gem gives me the following error

undefined method `best_in_place' for #<#:0x52efc18>

And in gems where I need to specify 'require [gem_name]', I got errors like

cannot find [gem_name]

This has been very frustrating to me, please help out, and let me know if there is any more information I should provide. Thanks!

At the top of your source file you need:

require 'name_of_gem'

for each gem you want to use.
