Atom-Editor：不要将 rubocop 与 atom 一起使用

Question

I tried connect rubocop in atom and got error in atom.

linter-registry.js [sm]:144 [Linter] Error running RuboCop Error: /usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'rubocop' (>= 0.a) among 16 total gem(s) (Gem::LoadError)

which rubocop return:

/usr/local/bin/rubocop

it's wrong?

Answer 1

It seems that you're using rvm to manage your environment. What i did to get it to work was follow the instructions on their repo: https://github.com/AtomLinter/linter-rubocop#settings

# make sure I'm in the global gemset
$ rvm gemset use global
# install the gem
$ gem install rubocop

configure atom to use the global. Edit your atom's config file ( config.cson ) and add

*:
  "linter-rubocop":
    executablePath: "~/.rvm/gems/ruby-2.3.1@global/wrappers"
  "linter-ui-default": {}

Note: make sure that the ruby version is the one you're using.

Answer 2

I had this same issue when working on a Rails 6 application in Ubuntu 20.04 with rbenv as my ruby version manager.

I already had rubocop installed in the project, but Atom editor was still throwing this error.

All I had to do was to install the rubocop gem to be available globally on the machine. Open a new terminal and install it using:

gem install rubocop

That's all.

I hope this helps
