CRX_REQUIRED_PROOF_MISSING errors

[slhck]

I am using Chrome Version 75.0.3770.100 (Official Build) (64-bit) under macOS.

When building an extension with crx3, I get the following error while installing:

CRX_REQUIRED_PROOF_MISSING

This is using the latest version of crx3 from npm.

@slhck yes, kinda. It's not that they changed format (AFAIK crx3.proto file did not change at all). It's just that they started enforcing web store signature. I commented about that at thom4parisot/crx#109.

Unfortunately, unless i'm mistaken, there's not much we can do about that on the CRX file's side of things :(.

Thanks for the info. Interesting thread. I guess we will close this then, although of course some caveat would be good to show to the users.

@slhck i added some info https://github.com/ahwayakchih/crx3#crx_required_proof_missing to README. I guess additional warning output in CLI would be more visible, but i'm not sure if adding non-real-error output to error log will break people's setups or not.

That's very useful, thanks. I don't think there needs to be extra output from the tool.

PS: You have a small typo (minifest.json).

Thanks, fixed :).
