arduino:avr:uno is not installed + failed to listen: listen tcp :50051: bind

[fhtino]

Arduino Pro IDE ( 0.0.2 )shows this error at startup:
"Editor support may be inaccurate because the core for the board arduino:avr:uno is not installed. Use the Boards Manager to install it."

Running from command line, I see this error when the IDE tries to start arduino-cli:

root INFO Error: Command failed: "C:\mybin\arduino-pro-ide-0.0.2-alpha.preview-windows\resources\app\node_modules\arduino-ide-extension\build\arduino-cli.exe" daemon -v --log-level info --format json --log-format json

Running ProIDE or directly Arduino-cli as administrator does not solve the issue.

@fhtino, can you please try to extract and run the application somewhere under %USERPROFILE%?

[fhtino]

@kittaakos I've run it under C:\Users\Fabry\temp\arduino-pro-ide-0.0.2-alpha.preview-windows\
Nothing changed: same errors on IDE and from command-line.

@kittaakos I've found a similar issue here docker/for-win#3171
I have HyperV installed. I've tried netsh on my PC. Port 50051 is included in the exclusion ranges.

C:\>netsh interface ipv4 show excludedportrange protocol=tcp

Thank you for your help, @fhtino. The CLI part is not under my control 😊, but I have opened a proposal. Hopefully, Windows users with Hyper-V installed, do not have to do any magic to be able to use the IDE.

If you have a better idea, please let us know.

This will be available with the 0.0.6-alpha release. You can use the CLI config to update the daemon.port.

I am moving this item to the current milestone as this feature will be supported by the next release.

[kittaakos]

@fhtino, you should be able to tune the daemon port via the CLI configuration.
File > Settings > Open CLI Configuration and change the daemon.port entry.

If you have questions/problems, please let us know.
