It means your Rails installation is corrupted or incomplete. If you list your gems, chances are you won't find railties

$ gem list

Run the command

$ gem install rails

again. It will download and install missing dependencies, including railties.

Is the railties gem present in the gem list? – Simone Carletti Feb 09 '12 at 14:07

Out of interest i had the same problem using windows, how would the installation or gems get corrupted? – Richlewis Feb 18 '13 at 12:00
Not only do I find railties, but I find 4 versions of railties installed in my gemset. – Daniel Viglione Dec 12 '17 at 00:11

I ran into the same problem and, in my case, it turned out to be because I had installed using sudo - it does not necessarily make rails available to ordinary users. Try running just gem install rails if you previously ran sudo gem install rails.

you shouldn't be using `sudo` to install gems. – sevenseacat Jul 21 '14 at 05:11

I ran into this same issue. If you're using RVM it's possible you switched to the wrong Ruby version which causes a gem load error if the directory uses a different version than the one you are currently set to use.

To fix, type rvm use -yourrubyversion in the app's directory in terminal. For example, if your app is set up to use ruby 1.9.3 type rvm use -1.9.3.

RVM works by separating your gems by ruby version by app, so if you switch to a different ruby version RVM will separate previously used and installed gems from the different ruby version, which is why you may be seeing tho issue.

This one did it for me. I had to use rvm use system, though. I was following the rails tutorial and had originally installed ruby and rails natively, and then decided later that I wanted rvm... so moral of the story is plan ahead and make sure you know what you want before you go installing these types of frameworks. At least Ruby has good docs and community support. — josiah, May 19 '13 at 00:10

rvm implode was the answer. Something probably went wrong before, now everything works after a rvm reinstall.

Take note that this will recursively delete all rvm environments. – cevaris Aug 07 '13 at 21:15

Maybe you installed two or more version of rails and railties.

gem uninstall railties
gem uninstall rails

then reinstall.

I did a bunch of reinstalls, and I fixed it with implode already. – pyronaur Mar 31 '12 at 23:04
And why is having more than one railties a problem? What if more than one railties is needed for different gems? I cannot install Rails because of this? – Daniel Viglione Dec 12 '17 at 00:12

Simone's answer is great. However, if you already have your Rails gem in your Gemfile, just try to use bundle exec instead:

bundle exec rails c

And that should suffice. If not, then add

bundle install

before the mentioned command.

I also had this issue after I installed ZSH (Wanted to mess with it's templates.)

Ran

brew update

which did find some updates I wasn't missing before, but in the end

gem install rails

suddenly completely re-installing the rail/ties system. Unsure why ZSH removed it.

Uninstalling ruby, and railsinstaller and then installing railsinstaller again worked great for me!

I did 'gem install rails' on my system (ubuntu) and it installed the missing gems approx 28 of them then i did 'gem list' to check and it was all there.
