By the look of it, it's winnus that has failed? You can probably still use it without that if you need.

Does npm install -g windows-build-tools first help?

i still get the same error, and when i run it, it says no ports found. I need to use it with Bluetooth for my Banglejs

Got similar error. Apparently node reference outdated. Fix: https://github.com/ilyapavkin/winnus/commit/c880fd30fc4ed45cc7f3daefbfdc882bbd989f1b node 12.18.3 vs2019

Thanks! Just pulled in those changes...

I just tried installing again and it still fails to build winnus

[gfwilliams]

Node.js probably updated again. It seems basically every new Node.js version they introduce some breaking change to the API :(

[OmegaRogue]

Maybe it would help to specify what Version of node and npm this requires to work, then people can just switch to that with nvm when they need to use this

I solved my problem by using the LTS version NODE. Build tools seem to be included in NODE 17.* which looks like it can cause it to hang. Works on Windows 10 and 11. Also, add --no-ble param when sending a file via espruino command line
