README for executePath doesn't match behavior in code

From the readme:

{
  // If not specified searches for 'rubocop' executable available on PATH (default and recommended)
  "ruby.rubocop.executePath": "",

From the code:

https://github.com/misogi/vscode-ruby-rubocop/blob/664e19bd104dd96d914c3e4d03f6f872a41830a5/src/rubocop.ts#L39

if (!this.path || 0 === this.path.length) {
            vscode.window.showWarningMessage('execute path is empty! please check ruby.rubocop.executePath config');

See also https://github.com/Microsoft/vscode/issues/26832 so now I get this warning on every single ruby tab I open.

If I do which rubocop and set the path to that directory, I now get the warnings in every tab:

"ruby.rubocop.executePath": "/Users/me/.rvm/gems/ruby-2.1.5@repo/bin/"

env: ruby_executable_hooks: No such file or directory

If I make it the file itself:

"ruby.rubocop.executePath": "/Users/me/.rvm/gems/ruby-2.1.5@repo/bin/rubocop"

/Users/me/.rvm/gems/ruby-2.1.5@repo/bin/rubocop + rubocop is not executable

What is the correct way to configure this plugin? The instructions and warnings don’t make sense.

[trejo08]

if you exec this command from your shell: user@your_computer:$~/which rubocop

that command will return something like this: /Users/your_user/.rvm/gems/ruby-2.3.1@global/bin/rubocop

you could copy that path and paste in your vscode config file as the value of the key that mentioned above:

{
  // If not specified searches for 'rubocop' executable available on PATH (default and recommended)
  "ruby.rubocop.executePath": "/Users/your_user/.rvm/gems/ruby-2.3.1@global/bin/",
}

ensure that you have installed rubocop in the specific gemset that you are putting in the vscode config file

by the example I used RVM, I have installed ruby 2.3.1 and I’m using the global gemset
