Regression in 0.3.1 - can't upload on any board

[brusherru]

Env

Windows 10
arduino-cli@0.3.1

Problem

Installing, compiling and etc works fine.
But when I try to upload compiled sketch onto my board (arduino:avr:leonardo) it throws:

panic: assignment to entry in nil map

I should have fixed this in 0.3.1 😨, let me do a quick check...

[brusherru]

@cmaglie it looks like 0.3.1 differs from 0.3.0 only by changes in the README.md 🤔

[per1234]

@brusherru here's the important commit between 0.3.0-alpha.preview and 0.3.1-alpha.preview that should have fixed this problem (it did for me at least): 5fc6787

[cmaglie]

@brusherru I've just tried 0.3.1 on a windows machine and it seems to work as expected, may you double check if it is really a 0.3.1 and not a 0.3.0? try to run arduino-cli version to be 100% sure.

@cmaglie @per1234 oh, you're right. It's my failure. Sorry 🙈

[cmaglie]

No problem, and thanks for all your feedback 👍
