heroku: command not found

Answer 1

run gem enviroment and look where is the EXECUTABLE DIRECTORY and add it to your PATH

In my case:

$ gem environment
RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.5
  - RUBY VERSION: 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
  - INSTALLATION DIRECTORY: /var/lib/gems/1.8
  - RUBY EXECUTABLE: /usr/bin/ruby1.8
  - EXECUTABLE DIRECTORY: /var/lib/gems/1.8/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86-linux
  - GEM PATHS:
     - /var/lib/gems/1.8
     - /home/user/.gem/ruby/1.8
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://gems.rubyforge.org/

$ export PATH=$PATH:/var/lib/gems/1.8/bin

or add to ~/.bashrc

Answer 2

I was using RVM, and my problem turned out to be the following:

• I had installed heroku using 'sudo'
• I should have installed heroku as the current user, without 'sudo'
