uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger (NameError)

rails 6.1.7.10

ruby 2.6.6.

Just did a bundle update to 6.1.7.10 from 6.1.7.8 Now running the application I receive the following error:

/home/cb/.gem/ruby/2.6.6/gems/activesupport-6.1.7.10/lib/active_support/logger_thread_safe_level.rb:16:in `module:LoggerThreadSafeLevel': uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger (NameError)

traceback shows:

rails console is unaffected

unable to find why this is now happening in the application

Solution

  • This appears to have broken the cocoapods integration in our iOS project. As above, running
    bundle add concurrent-ruby -v 1.3.4
    in the project root resolved the issue.
    This might cause issues down the road as cocoapods updates so keep an eye on that and remove this line if/ when that happens.

    Edit:
    Yes, I know this isn't answering exactly the question that is being asked and a little off-topic, but as an iOS developer, this post was the first result in google, therefore I thought I would leave hints for others like me. I assume that's why I'm getting downvoted.
