I read some other issues and that empty MIX_HOME= looks suspicious.
I've tried deleting ~/.cache/elixir-tools and .elixir-tools but it didn't help.

Same thing happens in VScode

[mhanberg]

I think I know what it is, thanks for the report!

[mhanberg]

the issue will close when the linked PR merges and i'll publish a new release, but we can re-open if it doesn't actually fix it.

[teamon]

It works now, thanks!
