python not found - had to configure it manually in npm

[mcollina]

On Mac OS X (Intel) v12.3.1 to make compilation of native modules work, I had to add the following to my .npmrc:

python=/usr/local/bin/python3

It took me quite a bit of time to find this trick.

This is with:

• node.js v16.14.0
• npm v8.5.5

Why is this needed?
Why can't node-gyp figure it out to try python3 instead?
Should we document this?

[cclauss]

Perhaps v12.3.1, not v12.13.1? Apple finally made good on its commitment to not bundle Python in the OS.

I believe that you can just type python3 on the command line and macOS will install it for you.

Most Mac developers would brew install python@3.10

Yes

I believe that you can just type python3 on the command line and macOS will install it for you.

python3 is actually there, not sure where it came from.

Most Mac developers would brew install python@3.10

[richardlau]

Can you run with logging enabled? The code should have attempted to try python3:

node-gyp/lib/find-python.js

Lines 118 to 122 in 1206a82

	{
	before: () => { this.addLog('checking if "python3" can be used') },
	check: this.checkCommand,
	arg: 'python3'
	},

[mcollina]

@richardlau how do I enable logging?

[richardlau]

--verbose, e.g. npm install --verbose

We'd be looking for, e.g. (from one of my Linux machines)

gyp verb find Python Python is not set from command line or npm configuration
gyp verb find Python Python is not set from environment variable PYTHON
gyp verb find Python checking if "python3" can be used
gyp verb find Python - executing "python3" to get executable path
gyp verb find Python - executable path is "/usr/bin/python3"
gyp verb find Python - executing "/usr/bin/python3" to get version
gyp verb find Python - version is "3.6.8"
gyp info find Python using Python version 3.6.8 found at "/usr/bin/python3"

[mcollina]

Ah yes, I understand what's the problem. On Mac it tries to install
xcode dev tools every time and it gets stuck for 15 minutes.

[mcollina]

I'll post the output later.

[cclauss]

I believe that a bare bone macOS has a python3 executable which is not the interpreter but is instead a stub which when run, asks the user if they want Python 3 installed. If the user says Yes then the installation of Python 3 happens which replaces that executable. The next time the user runs python3, they get the real deal. There was something similar in macOS for java. Does someone have a fresh macOS install that can prove that to be true?

[biodranik]

The built-in python3 executable is a valid pre-installed binary on the latest Mac OS X Monterrey:

$ which python
python not found
$ which python3
/usr/bin/python3
$ /usr/bin/python3 --version
Python 3.8.9

The problem is that the python binary is hard-coded somewhere in node-gyp instead of python3. python binary was removed from Mac OS 12.3. Installing any version of python3 from homebrew does not automatically link it (brew install python actually installs python 3.9). After doing brew link python the python symlink pointed to the installed python3 binary is created and node-gyp does not fail anymore.

node-gyp should properly detect that there is no python but only python3 in the PATH, and use that binary instead of failing.

[oscaredel]

For those using yarn in a (older) Rails app and a Python installation via pyenv, this finally solved it for me after hours of applying every possible suggested solution:

pyenv install 2.7.18

yarn config set python "/Users/$USER/.pyenv/shims/python2.7""

This will add that config to ~/.yarnrc

Also I made sure to undo as much of the previous given solutions in the other files like: ~/.zsh_profile ~/.zshrc ~/.npmrc

And finally I had to remove the yarn.lock file and update a webpacker version as is suggested here.

Then when running yarn it correctly installed everything.

[Fiorello]

npm config set python python3 worked for me

[cclauss]

Python 2 died 876 days ago on 1/1/2020 so it is no longer supported and @oscaredel must be relying on a very out-of-date release of node-gyp.

The solution of @Fiorello is aligned with our README.md.

[biodranik]

@cclauss but python, not python3 is still hardcoded here: https://github.com/nodejs/node-gyp/pull/2660/files#diff-d225e54970d51a7e4f86c99a7c0588d369a05ae27b2e5344c6102e215a7a663bL8

That's correct. The problem is that by default we cannot install binary modules and the result is a very cryptic error for those not familiar with the project. The user experience is really degraded and a tiny fix in this library could improve it quite a lot.

Specifically:

Instead of using xcode-install to get the cli tools, we should check if python3 is available.

[cclauss]

Xcode command line tools does NOT install Python. Node-gyp is using CLT for things like C/C++ compilers.

EDIT: The NOT is removed based on the evidence in replies below.

[cclauss]

Why are there no favorable reviews of #2660 so we can land it?

[biodranik]

@cclauss Calling /usr/bin/python3 on Monterey 12.3+ will ask to install Command Line Tools, and after that python3 binary will work.

[oscaredel]

Python 2 died 876 days ago on 1/1/2020 so it is no longer supported and @oscaredel must be relying on a very out-of-date release of node-gyp.

Yes, can confirm I sometimes have to maintain some low-maintained older applications. I'm not very familiar with this stuff. Honestly, I don't even remember now what I was working on then. I just did a write-up for what worked should anybody else run into a similar error and land on this page. So feel free to ignore any of my comments if they seem dumb.

[cryptobench]

npm config set python python3 also solved it for me. Thank you :-)

**Fiorello ** commented May 26, 2022

[simtrax]

I have a hard time finding a solution to this problem.
Have tried with npm config set python python3, and yarn config set python "/opt/homebrew/bin/python3", no success.

It still seems to try to use python.

@cclauss I saw a link to this PR #2362 but that does not seem to help me.

python commit_id.py check -->
python3 commit_id.py check

@cclauss I installed pyenv and added Python 2.7.
Then I also had to downgrade to Node 18, otherwise the package I wanted to install dit not install.
Don't know why that helped, but I'm happy it did.

[cclauss]

Python 2 died 1,058 days ago on 1/1/2020. Use it at your own risk.

@jacek213 Install pyenv, python 2.7. Set python 2.7 as global.

Python 2 died 1,091 days ago on 1/1/2020. Using it without any security updates in all that time is just asking for trouble.

For my case, it was better to make just symbolic link for python3 to python. it worked for me.

Python3 was Installed using brew before.

$ cd /opt/homebrew/bin
$ sudo ln -sf python3 python

The strong recommendation here is to create a venv which will give you a local python that you can pip install your project-related dependencies into without effecting other Python projects on your system.

This seems like it'll work, but for me it's failing because it looks for a very specific version of python:

Please use python3.10 or python3.9 or python3.8 or python3.7 or python3.6 or python3.5 or python2.7.
Node.js configure: Found Python 3.11.3...

Kind of silly, but I'll downgrade Python for now to get around it

You are not running a current version of node-gyp

this solution even working on ubuntu lts 20

@AI-Chef bad idea but it is your machine.

Instead of creating symlink and affecting other python projects, Create a venv in your current node project folder and do npm install again.
