If a user reports problems with the detection of Rubies installed with version manager, we need to debug it (works since 2018.2.1 EAP).
To do so, a user should start an IDE and open Help | Diagnostic Tools | Debug Log Settings (or find it via search action).
In the dialog opened, a user should put a logger id to enable debug logging:
- RVM - #
org.jetbrains.plugins.ruby.version.management.rvm.RvmSdkRefresher - Rbenv - #
org.jetbrains.plugins.ruby.version.management.rbenv.RbenvSdkRefresher - Chruby - #
org.jetbrains.plugins.ruby.version.management.chruby.ChrubySdkRefresher - Asdf - #
org.jetbrains.plugins.ruby.version.management.asdf.AsdfSdkRefresher
Then a user should click OK and restart IDE.
Now logging for respective SDK refresher is enabled, and the log should contain entries like this (for Asdf):
2018-07-30 16:57:18,237 [ 7350] DEBUG - nagement.asdf.AsdfSdkRefresher - Refreshing sdks
We need such a log to try to determine what went wrong.
