Unable to create default alias

[dymv]

Description

Steps to reproduce

1. Install fresh rvm from master
2. Get a stable ruby, 2.6.3 at the moment
3. Try to make the ruby version default by rvm alias create default 2.6.3

Expected behavior

I am able to make that ruby version the default one.

Actual behavior

I'm getting a bunch of errors regarding not being able to find these commands:

$ rvm alias create default 2.6.3

Moreover, that log file does not exist:
