Ruby gem fails to load

I've installed a gem from command line:

sudo gem install jalalidate

gem says it's installed:

$ gem list jalalidate
*** LOCAL GEMS ***

jalalidate (0.3.2)

And it can be loaded:

ruby -rubygems -e 'require "jalalidate"' # output is empty, (success?)

Though when I try to include this gem in a Rakefile, rake fails:

# Rakefile:
require "rubygems"
require "bundler/setup"
require "stringex"
require "jalalidate"

# Terminal:
$ rake new_post["title"]
rake aborted!
cannot load such file -- jalalidate

(See full trace by running task with --trace)

Note:

Update:

$ gem env

Your Rakefile has require "bundler/setup" before you try to require jalalidate which means you are using Bundler and so you have a Gemfile, which is restricting the gems (and versions) available.

In order to use the gem in your project, add the line

gem "jalalidate"

to the Gemfile.

See this question about why using sudo with gem commands is mostly a bad idea.

I recommend trying to install the gem without sudo: gem install jalalidate
