Use project directory's rvm ruby version

The VSCode Rubocop extension should be using the current project’s rvm/ruby version instead of the system default. The extension should be utilizing the same dependencies as the current project.

Not sure if #23 is related

Problem

When you are using something like rubocop-rspec it will install to the project’s ruby version, but the rubocop extension will not have access to the correct dependant gems because it’s using a different version that doesn’t have that gem installed.

Error Codes

When the extension tries to run I see something like this pop up:

cannot load such file -- rubocop-rspec /Users/codyswartz/.rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:120:in `require' /Users/codyswartz/.rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:120:in `require' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_loader_resolver.rb:15:in `block in resolve_requires' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_loader_resolver.rb:11:in `each' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_loader_resolver.rb:11:in `resolve_requires' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_loader.rb:43:in `load_file' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_loader.rb:82:in `configuration_from_file' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.58.2/lib/rubocop/config_store.rb:44:in `for' /Users/codyswartz/.rvm/gems/ruby-2.4.1/gems/rubocop-0.5...

This is a very hacky solution, but its working well for me. I created this file in my projects bin directory:

bin/vscode_rubocop

#! /usr/bin/env bash -l
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )/.."
cd "${DIR}"
rvm . do bin/rubocop "$@"

Then set the executePath to bin/vscode_, note the missing rubocop on the end, thats because it gets automatically appended to the executePath by the extension.

This assumes you have rubocop binstubbed.

I think I have found a more maintainable way to fix this among all the projects you have. On the settings set the Execute Path (ruby.rubocop.executePath) with the value rvm . do bin/bundle exec (with a space character at the end). Just that, is really easy. 👌
