Hi. I am trying to install the zerorpc-node on my system with Windows 10. Python 3.5 and Nodejs 10.16.0.
When i run npm install i get the following error

`npm install git+https://github.com/0rpc/zerorpc-node.git

zeromq@4.6.0 install path\node_modules\zeromq
node scripts/prebuild-install.js || (node scripts/preinstall.js && node-gyp rebuild)

Is this repo not compatible with Python 3.5?
How is a node module dependent on Python?

Any help would be appreciated. Thanks

I also encountered the same problem.

The package requires python2.x to do final setup, and it looks for python rather than python2, so just make sure your python goes to python2.x

[bruno-robert]

I'm also getting the same issue, tried alias python=python2 to no avail

@bruno-robert i think to work around this by using Python 2 you want to create a symlink (something like ln -s /usr/bin/python2 /usr/local/bin/python?), rather than an alias

That being said, it looks like newer versions of node-gyp have now added Python 3 support:
nodejs/node-gyp#1687 (comment)

Not 100% sure of the chain of events, but it seems like the zmq bindings are looking for a globally-installed version before falling back to their own version of gyp? So maybe try installing the latest node-gyp manually? (npm install -g node-gyp)

[bruno-robert]

It looks like it's using an old version of node-gyp that is bundled with npm.

Installing node-gyp globally only updates the global version, not npm's version.
$ node-gyp -v -> v7.0.0

but npm's node-gyp remains at an older version
/usr/local/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js -v -> v5.1.0

Either updating npm's node-gyp or getting npm to use the global node-gyp would fix this I believe.

I haven't had time to try the symlink trick. I will give it a go at some point.

EDIT:

Tried updating npm's packaged node-gyp with:
npm explore npm -g -- npm install node-gyp@latest (instructions for *nix/windows here)

zerorpc installation is still failing even with node-gyp v7.0.0

[gabrielgrant]

@bruno-robert hmmm, what's the error now?

[bruno-robert]

Since I didn't have the logs on me, I just retried installing zerorpc in a fresh folder after restart. It seems to have successfully installed (with multiple warning: 'MakeCallback' is deprecated [-Wdeprecated-declarations] warnings).
