Question

I’ve searched all around the web but haven’t been able to find a resolution to this error. Each time I attempt to either start the rails server, or even rails console I get a crack/xml (LoadError). Anyone have any suggestions that they believe might help me get rails up and running correctly?

I’ve attempted to install the crack gem then run bundler but I’m still given the same error, even after a reboot of terminal. So I’m not exactly sure how to solve this scenario.

Answer 1

What is sure: the error stems from the ap gem, this line.

It uses crack/xml as dependency but it’s not stated as a dependency in the gemfile son bundler can’t know it should be added.

How to fix?

• add the gem crack in your gemfile, before the ap gem

• or change the ap gem source code
