Because in my distro (Arch Linux) and many others, python3 is the default python interpreter (the "python" executable is a link for "python3").

You can use "python2" instead of "python" in the shebang line, this is a standard since 2011 PEP-394

TooTallNate · 2015-09-27T19:50:44Z

This was fixed in #527, but it looks like you're using an ancient version of node-gyp for some reason (v1.0.3, current version that bundles with node v4.1.1 is node-gyp v3.0.3). Try updating to the latest node-gyp / npm and things should work for you again.

(Also see #384, #502).

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

lordgreg · 2015-12-08T21:29:44Z

@TooTallNate thank you for your swift reply. I managed to fix the above error with removing Python 3.* and installing Python 2.* and giving its executable into $PYTHON env. variable. Of course I've thought I'd finally get everything working but no... now I need VS compiler 👎

MSBUILD : error MSB3428: Could not load the Visual C++ component "VCBuild.exe". To fix this, 1) install the .NET Framework 2.0 SDK, 2) install Microsoft Visual Studio 2005 or 3) add the location of the component to the system path if it is installed elsewhere.

I'll try to install VS Community Edition. But that's just great... just to make gyp to work, I have to install python and visual studio. Crazy! 🎱

sukrosono · 2016-02-16T08:17:54Z

@TooTallNate hi i still hit this issue as well

node v4.2.4
node-gyp v3.2.1
npm v3.7.2
python v3.5.1

i am not sure on my pc is valid issue, because i have install update node and npm

which is clear in my machine is

Error stack -> cant find python executable
Err command "my new node path" "old node path\\path to node-gyp.js" "rebuild"

sorry but i already try stackoverflow solution for this, and 3 of them fail.

bnoordhuis · 2016-02-16T08:31:43Z

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

sukrosono · 2016-02-16T08:52:09Z

@bnoordhuis thanks man, already did but lead to #307
i really going to far, since i just want install protractor. i verify that the file VCBuild.exe is not present.

any suggestion to find fastest way to satisfy this?
i won't and i can't install this one

bnoordhuis · 2016-02-16T08:57:19Z

You're going to need a compiler. You could give the instructions from #867 a try if VS is too big but one way or another, you're going to need some hard drive space.

sukrosono · 2016-02-16T09:27:54Z

i need time to add 7GB on my disk, so basically as long i need node-gyp i have to keep Microsoft Visual C++ build Tools with their 7GB hard drive space?

bnoordhuis · 2016-02-16T09:31:51Z

You can try a customized install. I think you only need the C++ compiler and the SDK. Preempting a "how much space will that take?" question: I don't know. :-)

ghost · 2016-05-29T23:40:59Z

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

chaffeqa · 2016-07-04T13:05:58Z

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

npm install -g node-gyp

geryit · 2017-01-12T00:28:37Z

npm install --python=python2.7 worked

SoulFireMage · 2017-02-07T11:56:08Z

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.

Pomax · 2017-02-23T05:45:10Z

Same. Running into

Error: Python executable "C:\Program Files\Python35\python.EXE" is v3.5.2, which is not supported by gyp.
gyp ERR! stack You can pass the --python switch to point to Python >= v2.5.0 & < 3.0.0.

Which isn't very useful. Python 2.5 and 2.6 are abandonware with only 2.7 actively supported, and no plans for ever releasing any version past 2.7.x, Python 3 in the mean time really is the main dev branch with minor versions rolling out at quite the steady pace. Installing 2.7 on windows at this point is usually more likely to cause problems than solve them due to conflicting python versions doing all kinds of bad things outside of node-gyp context (say, you work on 20 projects half of which require node and half of which require python3).

Checking the version of node-gyp that is used here, the script reports node-gyp@3.4.0 (with my node currently at v7.3.0), so this is very much still an issue.

gibfahn · 2017-02-23T06:59:44Z

@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 #1092 and https://github.com/indutny/gyp.js.

mgraszek · 2017-02-28T11:15:50Z

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

frekele · 2017-03-02T21:11:50Z

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

fcoclavero · 2017-05-24T14:55:05Z

@frekele this fixed the issue. Thanks!

mcrowe · 2017-11-01T22:26:17Z

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.

amnond · 2017-11-19T02:15:41Z

@mcrowe 👍 thanks, that sure saved me some time :-)

Doing some Friday house cleaning. When Python 3 is the default we can no longer do "yarn install" or "npm install" in the asclients repository, it will fail with an error. Upgrading to a more recent version of D3 will I think fix the problem because it will underneath upgrade jsdom to a newer version. See: https://github.com/activitystream/asclients/issues/412 nodejs/node-gyp#746

Borkes · 2017-12-26T04:43:21Z

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

cnrudd · 2018-01-12T14:06:54Z

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

prahaladbelavadi · 2018-01-14T07:39:28Z

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:

Cheers!

mnovak20 · 2018-01-15T03:54:36Z

I did --python=python2.7 as well after seeing

polease · 2018-02-13T04:37:44Z

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

codeadict · 2018-09-23T20:01:45Z

I actually use npm config set python /path/to/python2.7

yunnysunny · 2019-11-12T13:43:33Z

I have tried

npm install --python=/path/to/python2.7

set  PYTHON=/path/to/python2.7
npm install

But I node-gyp still use python3

cclauss · 2019-11-12T13:45:51Z

python2 --version
python2.7 --version
python3 --version
set PYTHON=python2
npm install

yunnysunny · 2019-11-12T14:32:46Z

set  PYTHON=D:\Python27\python.exe
npm install

failed, still used python3 to execute.

python2 --version

command not found

python2.7 --version

command not found

The building.gyp I used is https://github.com/Blizzard/node-rdkafka/blob/master/binding.gyp. I think the problem is not involved node-gyp, for it call python as a script:

https://github.com/Blizzard/node-rdkafka/blob/4f287802eeaabdf18eb4ffd61722de1b7e85b1dc/binding.gyp#L42

cclauss · 2019-11-12T16:10:07Z

Sorry... I was thinking Linux/Mac.

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