Version Clash While Loading 'activesupport' Gem

[SchallerJe]

Hi,
when executing "fastlane test" I get the following version clash:

.fastlane/bin/bundle/lib/ruby/site_ruby/2.2.0/rubygems/specification.rb:2275:in check_version_conflict: can't activate activesupport-5.0.1, already activated activesupport-4.2.7.1 (Gem::LoadError)

activesupport-4.2.7.1 doesn't even exist inside the gem directory. Any ideas?

Cheers,
Jens

Hmm, you shouldn't need to run from this plugin directly. That lane is only for the tests. Check out this documentation: https://github.com/fastlane/fastlane/blob/master/fastlane/docs/Plugins.md

Let me know if you're still having issues.

I know that this is only for testing. But I get the same error when using the plugin for my project. So it seems to be a general error.
This seems to be happening because your plugin needs activesupport >5 and fastlane is locked on version 4.
Maybe it's only on my machine, but any help would be awesome.

@SchallerJe Looks like a more recent version of fastlane updated the dependency?

Ok, now it works. The trick is to use bundler, set the version for activesupport to 4.2.7.1 in the Gemfile and use "bundle exec fastlane"
