Answer 1

rvm implode was the answer. Something may have gone wrong before, now everything works after reinstalling rvm.

Answer 2

This means that your Rails installation is damaged or incomplete. If you list your gems, chances are you will not find railties

 $ gem list 

Run the command

 $ gem install rails 

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

Answer 3

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

Answer 4

I ran into this problem. If you use RVM, you may have switched to the wrong version of Ruby, which causes a gem loading error if the directory uses a different version than the one you are currently configured to use.

To fix, enter rvm -yourrubyversion in the application directory in the terminal. For example, if your application is configured to use Ruby 1.9.3 such as rvm use -1.9.3.

RVM works by separating your gems from the ruby ​​version of the application, so if you switch to another ruby ​​version, RVM separates previously used and installed gems from another ruby ​​version, so you can see this problem.

Answer 5

Worked for me

 rvm reinstall 1.9.3 

then

 gem install rails 

Answer 6

You may have installed two or more versions of rails and rails.

 gem uninstall railties gem uninstall rails 

then reinstall.

Answer 7

I have the same error when I installed ruby ​​1.9.3p194

and then I reinstalled rubies and rails

Answer 8

Simon's answer is great. However, if you already have your own Rails-gem in the Gemfile, try using the package instead:

 bundle exec rails c 

And that should be enough. If not, add

 bundle install 

before the specified command.

Answer 9

I also had this problem after installing ZSH (Required to mess with the templates with it.)

Ran

 brew update 

which found some updates that I had not missed before, but in the end

 gem install rails 

suddenly completely reinstall the rails / ties system. It is not clear why ZSH deleted it.

Answer 10

Removing rubies and railsinstaller and then installing railsinstaller again worked great for me!

Answer 11

I made "gem install rails" on my system (ubuntu) and he installed the missing gems on about 28 of them, after which I made a "list of gems" to check, and it was all there.
