I think two things needs to be fixed:

• we shouldn't have these errors
• we should have silent errors in the build process (errors should fail the build)

AFAIK, at least for the two firsts, they depend indirectly to the adoption of recent version of gyp which itself depends of latest version of node-libzim.

Yes, I have been seeing those errors since I started working on mwoffliner, and I have no idea where they come from or what they are (from library code with old versions of node/ts maybe?), but they were very confusing the first time I saw them, especially since not only do they not fail the build process, but mwoffliner runs and works fine after they scroll past.

No hurry to fix them from my PoV, but better to have an issue to track the problem and bring awareness, especially about the fact that it is a known problem and we didn't found a simple solution.
