JSONDecodeError just after installation

[danilokleber]

Hi, thanks for the package and sorry if this is a dumb issue.

I installed the plugin but can't get it to work. I use asdf and edited the setting mentioned in the README. The stacktrace I get in Sublime console is the following:

Traceback (most recent call last):
