node-gyp: Python executable "python" is v3.4.3, which is not supported by gyp

If you are running into this issue while trying to npm install a package on MacOS, maybe you have installed a more recent version of Python using Anaconda. In that case you can make npm use the default version of Python installed with MacOS (2.7.x) using:

npm config set python /usr/bin/python

That should resolve the issue for you.

npm install --python=python2.7 worked

Resolved (npm 3.9.5, node 6.2.2, python 3.4.4) by running:

npm install -g node-gyp

@xing-kenny @lordgreg Please make sure you’re passing the --python argument to a Python 2 executable

@brutalcrozt Install python 2.7. If node-gyp doesn’t find it automatically, tell it where to look with --python /path/to/python2.7.

my python default is python3.6, I don’t want change it. So I using: node-gyp rebuild --python python2.7

This problem still exists unfortunately. It doesn’t like python 3.5 and I’ve tried installing python 2.7, which also fails in a myriad of ways.

I experienced a similar error Here’s what I did:

• Created new environment on Anaconda for python 2.7 named python-2_7-old
• Switched Environments

$ source activate python-2_7-old

It started working properly after that

Here’s what I found that was helpful:

• https://conda.io/docs/user-guide/tasks/manage-python.html
• https://conda.io/docs/user-guide/tasks/manage-environments.html#activate-env

Cheers!

Got this resolved by :

• Installing 2.7 on my machine https://www.python.org/download/releases/2.7/
• Setting the PYTHON path SET PYTHON=c:\path\to\python27\executable\python.exe
• checking if PYTHON was correctly added by executing:
  %PYTHON% And ensuring it gets the python command prompt
• Installing Visual Studio Community 2013 (sorry @brutalcrozt, - didn’t track how much space it takes; took close to an hour for the install to run)
• Running npm config set msvs_version 2013 --global
• Finally, running

> node-gyp rebuild

I use prahaladbelavadi’s method, it solve my issue.

I did –python=python2.7 as well after seeing https://stackoverflow.com/questions/20454199/how-to-use-a-different-version-of-python-during-npm-install

i have anaconda python 3.* installed. Apparently it is the default on my mac. Running plain old: npm install tulind --save gave me this error: Error: Python executable "/Users/**/anaconda/bin/python" is v3.6.0, which is not supported by gyp.

This worked for me, because I have python2.7 at /usr/bin/python: npm install --save --python=/usr/bin/python tulind

Sorry… I was thinking Linux/Mac.

py --version set PYTHON=“D:\Python27\python.exe” # with the quotes $PYTHON --version npm install

See: http://acdcjunior.github.io/node-gyp-windows.html

Error still shows up. I need to install python 2.7.13 to work with this plugin.

@Pomax Our upstream dependency gyp is Python 2 only, and as it’s now EoL (Google won’t be maintaining it) it’s unlikely that it will be updated to support Python 3.

Efforts are underway to remove/reduce our dependence on it, see https://github.com/nodejs/node-gyp/pull/1092 and https://github.com/indutny/gyp.js.
