Issue

Hello, I tried to build this great job on my Fedora 28. Then I found that it used some module relied on python 2 which is almost some out of date.

Hope it can be better and better! Thank you!

So I took a look at the node-gyp github page, and it does appear that it does not support any Python 3.x versions: https://github.com/nodejs/node-gyp#on-unix

My recommendation would be to open an issue on their github about this, as this package only uses node-gyp and doesn't have much control over that codebase :)

What module are you referring to that is using Python 2?

Just FYI, as far as I'm aware (and I'm not the author but an extremely heavy user of Cerebro), there is no Python code anywhere in the Cerebro codebase. There may be dependencies which may have some python code (the only thing I can think of that might have any python would be something to do with electron), but if that is the case, you might want to find the repository for that dependency and make an issue there instead :)

It seems that gyp is still using Python 2. When I executed yarn in ./app I got an error.

Here is the output message, hope it can help you. :)

I have been get similar error on Win10 using node version 10.15.2 and python2 (or python3). Was able to run yarn install successfully with yarn installed globally using node version 8.15.1 (installed using NVM) and PYTHON environment variable set to python2 executable location.
