   gem install rubocop

Now you can proceed to install the linter-rubocop plugin.

Settings

You can configure linter-rubocop by editing ~/.atom/config.cson (choose Open Your Config in Atom menu):

Using RVM

If you're using RVM and receiving errors in Atom that indicate Rubocop can't be found, you may need to change /bin to /wrappers in the path that gets returned from which rubocop before using it as your command setting. For example, change:

"linter-rubocop":
  command: "/Users/JohnDoe/.rvm/gems/ruby-2.2.4@global/bin/rubocop"

To:

"linter-rubocop":
  command: "/Users/JohnDoe/.rvm/gems/ruby-2.2.4@global/wrappers/rubocop"

Using rbenv

If you're using rbenv, it's recommended that you set your command to point to the Rubocop shim. This way, when you upgrade Ruby, the command will be a pointer to a Rubocop executable, regardless of your current Ruby version.

"linter-rubocop":
  command: "/Users/JohnDoe/.rbenv/shims/rubocop"

Using chruby

If you're using chruby , it's recommended that you set your command to execute chruby-exec to set version and run rubocop. Alternatively, you can reference the full intended path.

"linter-rubocop":
  command: "/usr/local/bin/chruby-exec 2.5.0 -- rubocop"

or

"linter-rubocop":
  command: "/Users/JohnDoe/.gem/ruby/2.5.1/bin/rubocop"
