Ruby on Rails: /bin/sh: rspec: command not found

Question

I\'m currently going through Michael Hartl\'s RoR tutorial and am stuck on Chapter 3 when trying to run Spork and Guard. When trying to run tests I get:

/bin/s

Answer 1

Now the RubyTest package has a configuration option called "check_for_rvm" that is disabled by default.

You can edit your ~/.config/sublime-text-2/Packages/RubyTest/RubyTest.sublime-settings file and set it to true. This worked for me without doing anything else.

Update: If you are using PackageControl you might need to reinstall the RubyTest package, instead of just updating it.

Answer 2

The sublime plugin is trying to run the command rspec using shell /bin/sh. However, the command is not found because RVM is not loaded in the shell's environment.

As such, the folder where your rspec executable is located is not in the shell's search path (PATH environment variable). RVM installs any executable commands that come with gems to someplace like: "/home/your-user/.rvm/gems/ruby-1.9.3-p194@myproject/bin/" (actual path depending on your gemset, ruby version, and where your OS stores user home directories)

Simple Solution

As mentioned here... you might find that simply executing sublime from a shell environment containing RVM (ie: your project directory) may solve the PATH problem. However, this requires that you execute your text editor from the command line each time, and that the shell's environment is preserved.

cd ~/src/my-ruby-project
subl .

After much experimentation, I found a way to force the RubyTest plugin to execute rspec with the correct RVM-controlled environment (with bundler support).

With Bundler Support

Here's the contents of my ~/.config/sublime-text-2/Packages/RubyTest/RubyTest.sublime-settings file:

{
  "erb_verify_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/bundle exec erb -xT - {file_name} | ~/.rvm/bin/rvm-auto-ruby -c",
  "ruby_verify_command": "~/.rvm/bin/rvm-auto-ruby -c {file_name}",

  "run_ruby_unit_command": "~/.rvm/bin/rvm-auto-ruby -Itest {relative_path}",
  "run_single_ruby_unit_command": "~/.rvm/bin/rvm-auto-ruby -Itest {relative_path} -n '{test_name}'",

  "run_cucumber_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/bundle exec cucumber {relative_path}",
  "run_single_cucumber_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/bundle exec cucumber {relative_path} -l{line_number}",

  "run_rspec_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/bundle exec rspec {relative_path}",
  "run_single_rspec_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/bundle exec rspec {relative_path} -l{line_number}",

  "ruby_unit_folder": "test",
  "ruby_cucumber_folder": "features",
  "ruby_rspec_folder": "spec",

  "ruby_use_scratch" : false,
  "save_on_run": false,
  "ignored_directories": [".git", "vendor", "tmp"],

  "hide_panel": false,

  "before_callback": "",
  "after_callback": ""
}

This should work as long as you've got bundler in your global gemset, and RVM installed to your home dir (adjust paths as needed if ~/.rvm does not evaluate correctly, or if bundler or rvm-auto-ruby is located somewhere else).

If you are using gemsets you should also add a line like the following to your project's .rvmrc file:

rvm use ruby-1.9.3-p327@your_project_gemset_name

Without Bundler Support

This assumes you have cucumber and rspec installed to the @global gemset of your current ruby:

{
  "erb_verify_command": "~/.rvm/bin/rvm-exec $(~/.rvm/bin/rvm current) 1>/dev/null erb -xT - {file_name} | ~/.rvm/bin/rvm-auto-ruby -c",
  "ruby_verify_command": "~/.rvm/bin/rvm-auto-ruby -c {file_name}",

  "run_ruby_unit_command": "~/.rvm/bin/rvm-auto-ruby -Itest {relative_path}",
  "run_single_ruby_unit_command": "~/.rvm/bin/rvm-auto-ruby -Itest {relative_path} -n '{test_name}'",

  "run_cucumber_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/cucumber {relative_path}",
  "run_single_cucumber_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/cucumber {relative_path} -l{line_number}",

  "run_rspec_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/rspec {relative_path}",
  "run_single_rspec_command": "~/.rvm/bin/rvm-auto-ruby $(~/.rvm/bin/rvm gemdir | sed -e 's/@.*//' -e 's/$/@global/' )/bin/rspec {relative_path} -l{line_number}",

  "ruby_unit_folder": "test",
  "ruby_cucumber_folder": "features",
  "ruby_rspec_folder": "spec",

  "ruby_use_scratch" : false,
  "save_on_run": false,
  "ignored_directories": [".git", "vendor", "tmp"],

  "hide_panel": false,

  "before_callback": "",
  "after_callback": ""
}

Answer 3

From the terminal, try 'gem list -d rspec'. That should print out any gems you have w/ rspec in the name. If there aren't any, try 'gem install rspec'.

Assuming that, from terminal, you do have rspec installed (which you can verify with "which rspec", etc.), in that case your problem is likely to do with how Sublime is configured. Note the path where rspec is installed and check whether your editor has that in its paths.

(Sorry, I'm not familiar with Sublime in particular.)

Answer 4

Refer to the Bundler settings: https://github.com/maltize/sublime-text-2-ruby-tests

About RubyTest.sublime-settings, it should be under your home folder somewhere in sublime-test2/Packages/RubyTest folder. In the case of Ubuntu it would be:

~/.config/sublime-text-2/Packages/RubyTest

Answer 5

You need to start sublime from terminal within the working directory: example - (goto working directory in terminal, then start sublime from terminal )

cd rails/my_app_dir
subl .

Answer 6

if you've used rbenv during installation of Ruby in Mac and have issue with running "rspec" after installation "rspec gem", like: "-bash: rspec: command not found", just refresh it by typing command:

rbenv rehash
