Please, help me to switch to the Python 3.10 under macOS environment!

Hello everyone!

I'm not a professional coder, it's my hobby and passion.
But I've created an Open Source app for ear training on equalization, written in Python.
I build the binaries successfully for Windows and for macOS (x86_64) on my local computers with PyInstaller, with my spec files, running pyinstaller macos_build.spec or pyinstaller windows_build.spec correspondingly.

Though, I'm quite new to AppVeyor, I could build the Windows part of my recent release with it.

But unfortunately, I couldn't do the same on macOS environment.
I really need that, because my goal is to build a release both for x86_64 (Intel) and arm64 (Apple Silicon) platforms. I tried to do this for Intel first, because I own mac mini with i7, and I can test the binary manually.

The current codebase is adapted to Python 3.9 and 3.10. I do not know all the upcoming pitfalls yet, but the first problem I encountered with was that I simply couldn't switch from Python 3.8.9 to one of above-mentioned. Unlike the instructions for Windows, the macOS part of the documentation declares, that Python 3.10.8 is installed, but it has no paths.

I tried the following ones with no luck:


I tried several different settings like this:

image: macos-bigsur
    - PYTHON: "/Applications/"
      PYTHON_VERSION: "3.10.11"
      PYTHON_ARCH: "64"
  - export PATH="$PYTHON:$PYTHON/bin:$PATH"

No luck...

I even tried to use python3.10 command instead of python or just python3, and it says:

/usr/local/Cellar/appveyor-build-agent/7.0.3212/ line 51: python3.10: command not found

I would appreciate your help!

Thanks in advance!!!

    Did you try locating the desired python binary at $HOME/venv3.10 as is done on linux builds?
    Also, I see you have the command pip -U install... but -U is an option for the install command so should come after.

    No, I haven't. I'm not familiar with Linux at all...
    Could you give me the right settings for YAML file, please?

    As for pip -U install, yeah, right you are, thanks!


    I have just built an artifact, installing Python 3.10 from scratch with homebrew (under macos-monterey) and creating the Python virtual environment:

      - brew install python@3.10
      - python3 -m venv venv
      - source venv/bin/activate
      - python3 -m pip install -r requirements.txt
      - python3 -m pip install -U pyinstaller
      - pyinstaller macos_build.spec

    But there are two issues:
    - The smaller one is that the installation takes too much time;
    - And the bigger one is that the AppVeyor macOS environment seems to have issues with symlinks. In the cases when PyInstaller (the same version, the same *.spec file) normally creates symlinks, it duplicates the files instead. So, the resulting *.app bundle is three times bigger than it should be, and it doesn't work...

    This case is described in PyInstaller documentation:

    Failing to preserve symbolic links will turn them into full file copies; the duplicated > files will balloon the size of your frozen application, and may also lead to run-time issues.

    Should I create a separate ticket for that?

    Thanks again!

    And also, I didn't understand, how I could locate the desired python binary anywhere inside your virtual machine, if I don't know your macOS python paths... They are not documented. I tried to guess them with no success...

    Finally, this worked!

    • chmod +x $HOME/venv3.10/bin/activate
    • source $HOME/venv3.10/bin/activate
