Rails 5: Array values in the parameter to `Gem.paths=` are deprecated

Question

Building websockets app based off of actioncable-examples. When starting server, running rake, etc. I keep getting the message:

Array values in the paramet         


        

Answer 1

I also face same error in my rails 4.2.7 application and I fixed the error to update bin/spring file line no 11

Gem.paths = { 'GEM_PATH' => [Bundler.bundle_path.to_s, *Gem.path].uniq.join(Gem.path_separator) }

Answer 2

I found the answer in RubyGems issue #1551 here. The binstubs, the files in the bin folder, need to be updated. The best way to do this is:

bundle update spring
bundle exec spring binstub --remove --all
bundle exec spring binstub --all

And that resolved the problem for me.
