在ExpandPathArguments上的rubocop错误

Question

I have this rubocop error

Offenses:

fastlane-plugin-lizard.gemspec:1:12: C: Style/ExpandPathArguments: Use expand_path('lib', __dir__) instead of expand_path('../lib', __FILE__).
lib = File.expand_path("../lib", __FILE__)
           ^^^^^^^^^^^

10 files inspected, 1 offense detected
RuboCop failed!
Exited with code 1

How do I fix this error? cos follow rubocop advise I will get another error

#!/bin/bash -eo pipefail
bundle check || bundle install --jobs=4 --retry=3 --path vendor/bundle

[!] There was an error parsing `Gemfile`: 
[!] There was an error while loading `fastlane-plugin-lizard.gemspec`: cannot load such file -- fastlane/plugin/lizard/version
Does it try to require a relative path? That's been removed in Ruby 1.9. Bundler cannot continue.

Answer 1

Change

lib = File.expand_path("../lib", __FILE__)

to

lib = File.expand_path("lib", __dir__)
