Question

I am trying to start a new Rails project but I am getting a really strange error. When I do:

rails new my_project 

I get a error:

/usr/local/Cellar/ruby/1.9.3-p125/lib/ruby/1.9.1/rubygems.rb:314:in `bin_path': can't find gem rails ([">= 0"]) with executable rails (Gem::GemNotFoundException)
    from /usr/bin/rails:19:in `<main>'

What should I do to start a new project ?

Answer 1

It seems like rails isn’t actually installed.

You can install it with gem install rails.

If it seems unlikely that it isn’t installed, try running gem list --local | grep "rails".

If it returns something, then make sure your rubygems aren’t configured for a different ruby install by running gem environment.
