The installation seems to have worked and I can still use the package using dtrace normally (https://github.com/AzureAD/passport-azure-ad).

Why is this warning so giantic AND ignored ?

Shouldn't it just warn ?

Cheers,

@cadesalaberry The error is large since it's coming from inside node-gyp and including its stack plus npm's. It's ignored since compilation failure usually isn't a problem for most people and environments, and falling back on the stub provider is fine.

Unfortunately, there isn't a way for this library to suppress that error message. If you install node-gyp's requirements (Python 2 and GNU Make should be sufficient on Linux), then the error message will disappear.
