Error when trying to release private pod: Gem::LoadError: Unable to activate cocoapods-0.33.1, because activesupport-4.0.2

Question

When running rake release with a Rakefile generated by Cocoapods to release a version of my private pod I get the following error:

Gem::LoadError: Unable to activate cocoapods-0.33.1, because activesupport-4.0.2 conflicts with activesupport (< 4, >= 3.2.15)

I understand that there seems to be a dependency conflict, but don't know how to resolve it. I tried uninstalling cocoapods (with gem cleanup cocoapods and gem uninstall cocoapods) and tried removing old versions of other gems with gem cleanup (which seemed to delete a lot of stuff). But that didn't help.

Also, since I'm not actually doing ruby development but just use the generated rake file to release a cocoa pod, I don't think that Bundler would help me, or does it?

Any ideas how to fix that?

Answer 1

You just need to downgrade the version of activesupport.

Run gem uninstall activesupport and delete any versions that are >= 4. If you had a valid previous version installed already then you should be good to go.

If you don't run gem install activesupport --version 3.2.18 to get a valid version.
