It seems to me that this is related to node-gyp rather than this module itself.

[UPDATE] According to this SF question this issue maybe related when using Python 3.x instead of Python 2.7 when on macOS If this is the case, how to make node-gyp to use the old version of python. When on macOS we now have python 3.7.7 with brew by defaults, so my workaround was:

brew install python@2 (if for some crazy reason it was removed, very unlikely
brew link python@2

or to force the latter brew link --overwrite --dry-run python@2 and then you should get both python (python2) and python3 installed.

It's important to notice the since node-gpy still requires python to be Python2.7 you need also to specify the right library path, then you may want to alias it in .bash_profile:

function __py3 {
    export PYTHONPATH=/usr/local/lib/python3.7/site-packages/
}
function __py2 {
    export PYTHONPATH=/Library/Python/2.7/site-packages
}
alias py3='__py3'
alias py2='__py2'

My two cent. Why node-gyp does not upgrade to Python3?

[cclauss]

You have two different node-gyp installed... v6.0.1 and v5.0.5 (see the error log).

Please upgrade gyp ERR! node-gyp -v v5.0.5 to https://github.com/nodejs/node-gyp/releases

[loretoparisi]

@cclauss thanks, I can only see

ip-192-168-1-168:Projects loretoparisi$ which node-gyp
/usr/local/bin/node-gyp
ip-192-168-1-168:Projects loretoparisi$ node-gyp --version
v6.0.1

[cclauss]

Please look through your log above:

gyp ERR! node -v v12.13.1
gyp ERR! node-gyp -v v5.0.5

[loretoparisi]

@cclauss thank you. So if I do a locate node-gyp I cannot find the offender version v5.0.5 under path like

/usr/local/n/versions/node/
/usr/local/lib/node_modules/npm/node_modules/node-gyp
/usr/local/Cellar/node/
/Users/loretoparisi/.node-gyp/

etc.

[cclauss]

/Users/loretoparisi/Documents/Projects/node_modules/node-gyp/gyp ?

[loretoparisi]

while I have all these (not sure why actually!)

/Users/loretoparisi/.node-gyp/
10.0.0/  10.1.0/  10.15.3/ 11.1.0/  6.9.4/   8.11.1/  8.11.2/  8.12.0/  8.9.1/   8.9.4/   9.11.1/  

I think I have found it here

 /usr/local/lib/node_modules/npm/node_modules/node-gyp/gyp/gyp --version
ERROR:root:code for hash md5 was not found.

since it crashes and it is linked to Python2. Do you think is the right one? Under setup.py I can see

hey @loretoparisi :)

I ran into this issue myself -- turns out I just needed to updated NPM itself (which has node-gyp as a dependency)

npm i -g npm

[tekumara]

Thanks @wulf, npm i -g npm fixed this for me! (I'm using node v11.15.0 on Darwin 19.6.0)

[loretoparisi]

@Wulf great, thank you! in fact it worked with node v12.16.1, npm v6.13.4, node-gyp v6.0.1. Closing then.
