Installed Rails but the rails command says it's not installed

Question

I'm using Ubuntu 9.10 Karmic Koala and Ruby 1.9.1.

I installed Rails using sudo gem install rails, which installed all the libraries for me.

When I type rails in the terminal it says.

The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails rails: command not found

I can find rake, which is under rake1.9.1, but Rails is nowhere to be found, can someone point me in the right direction?

Edit: path to ruby isn't the problem, the problem is where is rails? how do I execute it? rails just doesn't work, where does the exectuable lives?

Solution 1

As others say, this may very well be a PATH variable issue on your bashrc/bash_profile file.

You can learn how to change PATH..

You can get the current PATH variable by typing echo $PATH

Solution 2

If you're running a rails command immediately after installing rails, you will need to restart your terminal before your commands will be recognized.

Solution 3

Just had the same issue just put the following in your .bashrc

PATH="${PATH}:/var/lib/gems/1.8/bin/"

Solution 4

Assuming ruby-2.0.0-p247 is installed, rails is located at following location.

prayag@prayag$ ls -l ~/.rvm/gems/ruby-2.0.0-p247/bin/

[1] .bash_profile should already be containing following line, if not add.

 [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

[2] Add following line to the end of .bashrc.

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
PATH="${PATH}:${HOME}/.rvm/gems/ruby-2.0.0-p247/bin/"

[3] Reload ~/.bashrc

$ source ~/.bashrc

And, it should work.

If you’re running rbenv you’ll need to run rbenv rehash go get access to the rails-api command.

The problem isnt with ruby, ruby works great. But when running rails it says its not installed, although if I do gem list, it will properly show to me, rails 2.3.5

[rgoytacaz]

it isnt a problem of putting the path there, it seems rails it not installed at all, how do I check if its really installed? whats its executable? where does it lives?

[Priyank]

I looked up the bin folder of my ruby installation. It has a "rails" file. If i rename that to anything else and try to run rails; it doesn't scaffold or create projects..instead says that rails is not installed do sudo apt-get install to install rails. But if I rename it back to rails; then it starts working. So I am pretty sure that as long as rails is installed properly and you have it in bin folder it should run. Maybe I haven't installed it as a gem plus I am using JRuby.

Run gem environment and you'll find EXECUTABLE DIRECTORY.

[rgoytacaz]

You ARE GREAT! THANKS TK! Thats exactly what I needed. It turns out that installing it through gem doesnt create a symlink. I created it and points it to the executable directory. working great

PATH="${PATH}:/var/lib/gems/1.8/bin/"

@rgoytacaz how do you create a symlink?

Be careful when posting copy and paste boilerplate/verbatim answers to multiple questions, these tend to be flagged as "spammy" by the community. If you're doing this then it usually means the questions are duplicates so flag them as such instead: stackoverflow.com/a/13149543/419

Flagged. I'll be more careful about that. The answer may helpful to those that come across either post (like me), which is why I shared it.

@Hlung Use sudo ln -s /usr/local/bin/rails /usr/bin/rails or change it accordingly.
