Comment 7 Stephen Gallagher 2020-03-11 00:55:45 UTC 
Can you please provide some additional details around what you were attempting to do here? It appears that you were trying to build npm itself and hit a bug with its support for Python 3 to build.

Comment 9 Stephen Gallagher 2020-03-16 12:22:21 UTC 
OK, I'm making a bit of a guess here, but I think what's happening is that node-gyp is incorrectly assuming that if python is invoked from /usr/bin/python, it must be python 2 (but on F31+ it's actually python 3). I'm adding a patch to /etc/npmrc that will set the default python interpreter explicitly to /usr/bin/python3 to hopefully work around this.
Comment 10 kb1000 2020-03-16 16:57:31 UTC 
I'm sorry for not responding earlier, but I didn't try to build npm itself, but try to install node-sass 4.13.1 using yarn from https://classic.yarnpkg.com/en/docs/install/#centos-stable .
It pulled in deasync 0.1.19, this happened during the build of that package. Would yarn be fixed too by that patch?
