[ACCEPTED]-Installed Rails but the rails command says it's not installed-gem

As others say, this may very well be a PATH 3 variable issue on your bashrc/bash_profile 2 file.

You can learn how to change PATH..

You can get the current PATH variable 1 by typing echo $PATH

If you're running a rails command immediately after 3 installing rails, you will need to restart 2 your terminal before your commands will 1 be recognized.

Just had the same issue just put the following 1 in your .bashrc

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

Assuming ruby-2.0.0-p247 is installed, rails is located at following 3 location.

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

[1] .bash_profile should already be containing 2 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 1 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 2 rbenv rehash go get access to the rails-api 1 command.

gem should have placed the rails executable 3 script in the same location as ruby's. I'd 2 look in there and make sure the permissions 1 are set correctly and it is executable.

I think this is not correct way to resolve 10 this problem. But What I have done is, I 9 have created a rails.rb file in my executable 8 directory because when I open that directory 7 file was not there and put the following 6 content.

#!/usr/bin/env ruby_noexec_wrapper
#
# This file was generated by RubyGems.
#
# The application 'railties' is installed as part of a gem, and
# this file is here to facilitate running it.
#

require 'rubygems'

version = ">= 0"

if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
  version = $1
  ARGV.shift
end

gem 'railties', version
load Gem.bin_path('railties', 'rails', version)

then I try to run rails s in my project 5 and its works..

But before this make sure 4 that executable directory is in your path 3 like I have already in my machine : /home/anand/.rvm/gems/ruby-1.9.3-p286/bin:/home/anand/.rvm/gems/ruby-1.9.3-p286@global/bin:/home/anand/.rvm/rubies/ruby-1.9.3-p286/bin:/home/anand/.rvm/bin

As per 2 TK said you can get the executable path 1 using gem environment command

I added the following lines to my .bashrc 3 file and it worked.

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source 2 "$HOME/.rvm/scripts/rvm" # Load RVM into 1 a shell session as a function

PATH="${PATH}:${HOME}/.rvm/gems/ruby-1.9.3-p327/bin/"

If you are using rbenv don't forget add

eval "$(rbenv init -)"

into 2 your .bash_profile or other start up scripts. run rbenv rehash is 1 also needed.

A possible solution is to not maintain two 6 different configuration files .bash_profile and .bashrc

It's 5 suggested in this excellent post on the 4 difference between .bash_profile and .bashrc is to source .bashrc from 3 your .bash_profile file, then putting PATH and common 2 settings in .bashrc.

Quoting,

add the following 1 lines to .bash_profile:

if [ -f ~/.bashrc ]; then source ~/.bashrc fi

end quote

I am using macOS and in my case, I needed 2 to add this line to ~/.zshrc:

export PATH="/usr/local/lib/ruby/gems/3.1.0/gems/railties-7.0.2.3/exe:$PATH"

It can be done like 1 this:

echo 'export PATH="/usr/local/lib/ruby/gems/3.1.0/gems/railties-7.0.2.3/exe:$PATH"' >> ~/.zshrc

My ruby was installed by brew.
