如何为IntelliJ IDEA的Ruby插件设置SDK？

Question

Using IntelliJ Idea 15.0.6 with the Ruby plugin v.8.0.0.20160205

After encountering various Ruby SDK problems, I followed these instructions to re-configure my inherited Ruby project: https://www.jetbrains.com/help/idea/2016.1/configuring-global-project-and-module-sdks.html

I now have a global SDK:

And a project SDK:

And a module SDK (inherited from the project SDK)

But gemfiles showed a bunch of inspection problems

And I was not able to create a Run/Debug Configuration using the module SDK. Specifically, if I selected the "Choose SDK from module" radio button for Ruby SDK when creating a new Run/Debug Configuration, I would see the error "No SDK specified" at the bottom of the window.

What is going on?

Answer 1

Turns out that the module was not a Ruby module. This is what it should look like:

I deleted the module and recreated it and everything is working correctly. Many times I've found that the process of writing out a question is a great way to answer it myself.
