I got a panic when I wanted to install a lib from ZIP.

Expected behavior

Environment

• CLI version (output of arduino-cli version): nightly-20210224
• OS and platform: macOS 11.2.1

Additional context

[kittaakos]

It's affecting the nightlies only.

Any update on this? still getting this problem on alpha Version: nightly-20210928 Commit: 4708cde Date: 2021-09-28T01:27:37Z

Also getting this problem when trying to install from a git url.

I need to be on nightly because of #1448 which seems to have not been built to release yet.
