I'm investigating this issue right now since it's blocking my work. Here's what I've learned:

builder-util is trying to call python because the package dmg-builder uses python scripts
You can set the environment variable PYTHON_PATH to overwrite the default of /usr/bin/python, however:
dmg-builder uses the reload module, which is only available builtin in Python 2

So presumably, setting PYTHON_PATH to a python2 installation could work around this issue. I'll be trying that next.

scowalt · 2022-03-17T02:20:39Z

FYI, this may be a dupe of #6606

@scowalt did you manage to make it work by setting the PYTHON_PATH? I can't update electron-builder because it'll break other things

I ended up just updating electron-builder, so I never finished testing PYTHON_PATH.

@hjMaGitHub , it looks like vue-cli-plugin-electron-builder is still potentially using an old version of electron-builder. If you use Yarn, you can use selective dependency resolutions to force that module to use the newer electron-builder. I don't know how to do that with NPM

if you use yarn,after install python2.7.18 and fix the python's path, you can add this code in package.json to fix it
"dependencies": {
....
}
"devDependencies": {
...
}
"resolutions": {
"vue-cli-plugin-electron-builder/electron-builder": "^23.0.3"
}

yarn is ok, I'm not try it in npm

npm (native) solution to this are npm overrides. See example here.

samowolabi · 2022-04-15T15:25:14Z

This should work 😁.
Go to node_modules/dmg-builder/out/dmg.js.
In "dmg.js" file, search replace "usr/bin/python" to "usr/bin/python2".

*Note: Python v2 must be installed, and check if this directory exists by pressing "sudo cd usr/bin/python2".

The reason why this error exists "Exit code: ENOENT. spawn /usr/bin/python" is because "ENOENT" means no existing directory. The version of the python cant be found.

thx @lylyong the resolution "vue-cli-plugin-electron-builder/electron-builder": "^23.0.3" is very great

camellieeee · 2022-12-09T09:36:36Z

May be change dmg.js and dmg.js.map can solute the problem. /usr/bin/python -> python2

willian12345 · 2022-12-21T06:11:35Z

python2

As on my Mac, It works after next steps

find the python2 real path use which python in terminal after reinstall python2, It will be like /Library/Frameworks/Python.framework/Versions/2.7/bin/python
open /node_modules/dmg-builder/out/dmg.js In your project
Use /Library/Frameworks/Python.framework/Versions/2.7/bin/python replace "/usr/bin/python" in dmg.js
Save it

The GitHub-hosted runners began experiencing issues while building macOS desktop distributions, exclusively affecting the macOS environment. The Ubuntu and Windows environments remained unaffected. The logs highlighted the absence of Python in the macOS environment, which resulted in build failure: ```sh Error: Exit code: ENOENT. spawn /usr/bin/python ENOENT ``` Since the `electron-builder` package uses Python scripts to create DMG disk images for macOS distributions, Python is needed for building the application. However, electron-builder uses Python 2.X meanwhile modern macOS versions have removed Python 2.X from the operating system on default installation. Although this issue was resolved in `electron-builder` version 23,, `vue-cli-plugin-electron-builder` continues to use version 22. Due to a lack of maintenance, the package is unlikely to receive updates. This commit forces `vue-cli-plugin-electron-builder` to use the latest `electron-builder` which resolves the macOS distribution build failure. In CI process, GitHub-hosted runners start to fail when building macOS desktop distributions. It is only observered in the macOS environment while the application is built successfully in both the Ubuntu and Windows environments. The error message in the logs indicated that Python was not found in the macOS environment: ```sh Error: Exit code: ENOENT. spawn /usr/bin/python ENOENT ``` `electron-builder` package uses Python scripts for certain operations, specifically for creating DMG disk images for macOS distributions. As a result, Python is a necessary dependency when building the application for macOS. `electron-builder` has fixed this starting from version 23, but vue-cli-plugin-electron-builder still refers to version 22 and it is unmaintained and not likely to get updates. The solution is to add a step in the GitHub Actions workflow to set up Python in the macOS environment. `actions/setup-python` sets up the Python environment in the runner if the OS is macOS. This change does not impact the Ubuntu and Windows environments as the setup-python step is conditionally executed only for macOS. The addition of Python to the macOS environment in CI process has resolved the build failure issue for the macOS distribution.

I also updates the `package-lock.json` to the v3 format. Now the app compiles again, too! Looks like I ran into this issue with Electron-Builder here, I'm pretty sure. electron-userland/electron-builder#6726

2024 and none of the mentioned solutions above worked for me.
For anyone out there still facing this issue till today.
If you are on Apple silicon M1/M2 or M3, you might want to do this.

PS: i am using the eletron-builder in a vuejs app, just FYI

Problem: Firstly, this is a python problem like mentioned above, however since MacOS doesn't ship with default python anymore it's an issue. It seems like the "vue-cli-plugin-electron-builder": "~2.1.1" package hasn't been updated yet with the latest builder version which as of today is "electron-builder": "^24.9.1",. and it appears the version vue-cli-plugin-electron-builder is not yet compatible with the the new arm64 architecture.

Solution:

install electron-builder with npm i electron-builder
update your package.json with the code below. This forces override via npm:

    // other dev dependencies
    "vue-cli-plugin-electron-builder": "~2.1.1"
  },
  "overrides": {
    "vue-cli-plugin-electron-builder": {
      "electron-builder": "^23.0.6"
    }
  }

Works like charm✨

PS: Another untested solution which could theoretically work is, you should find a way to install python 2.x (I think) and update the environment variables so it can find it in the path usr/bin/python

async-promise · 2024-07-12T04:03:57Z
