Yarn doesn't correctly handle optional dependencies

• Version: 10.16

• Target: all

First of all thanks for this great tool! 🥇

I experience one problem only present when using electron-builder together with yarn:

electron-builder will fail if a optional dependency errors during install. npm handles this correctly and doesn’t throw a error. yarn itself also handles optional dependencies correctly if electron-builder’s postinstall/rebuild script isn’t used.

Here is a concrete example: We are using electron-builder inside nteract but one of our dependencies requires canvas as a optional dependency (which we don’t need inside Electron). Installing canvas will likely fail on some systems and will make our whole build fail if we use yarn for installing.

Please set env DEBUG=electron-builder and attach log of the terminal output.

Thank you for warm words 😃 Fix landed in the 11.2.1.
