Cannot build lorawan stack

[dsmith]

Running tools/bin/mage js:build fails while following the development instructions on github. I’m on the 3.10.1 tag in the hope it would be more stable but I see similar issues on top of the default branch.

Hey @dsmith, did you try following the console troubleshoot guide of the development instructions? Specifically this section?

Also, please try the following commands: tools/bin/mage jsSDK:cleanDeps jsSDK:clean js:cleanDeps js:clean js:build, which will clean up all caches and modules. This often fixes build issues.

Thanks Kevin, I hadn’t seen that troubleshooting guide. I’m afraid I’m still seeing the same issues though. After yarn cache clean and npm cache clean --force this is what I get:
