Installation of Qt 5.15.2 on macOS fails with python exception KeyError(name)

[dalboris]

First of all, thanks for developing and maintaining this action!

The action was working perfectly up to yesterday, but I just did another commit today and the action is now failing, see the job here:

https://github.com/vgc/vgc/runs/1972493790

python3 -m aqt install 5.15.2 mac desktop -O /Users/runner/work/vgc/Qt

During handling of the above exception, another exception occurred:

Not sure what's wrong, I haven't tried investigating yet what the problem is, just reporting here.

Here is the workflow Yaml file that I use:

https://github.com/vgc/vgc/blob/master/.github/workflows/macosbuild.yml

Relevant subset:

name: macOS Build

on: [push, pull_request]

env:
  BUILD_TYPE: Release
  QT_VERSION: 5.15.2

jobs:
  build:
    runs-on: macos-10.15

    steps:

    [...]

    - name: Install Qt
      uses: jurplel/install-qt-action@v2
      with:
        version: ${{env.QT_VERSION}}
        setup-python: false

    [...]

Perhaps I need to set setup-python to true, I don't remember why I have explicitly set it up to false (perhaps it was too slow?).

[dalboris]

Alright, I fixed the problem.

The reason I had disabled install-qt-action > setup-python is that my build requires to use a specific version of Python, in this case Python 3.7. So I am in fact explicitly setting the version of Python in one of the steps, here was the relevant YAML:

    - name: Setup Python
      uses: actions/setup-python@v2
      with:
        python-version: '3.7'
        architecture: 'x64'

    - name: Install python packages
      shell: bash
      working-directory: ${{runner.workspace}}
      run:
        pip3 install dmgbuild

    - name: Install Qt
      uses: jurplel/install-qt-action@v2
      with:
        version: ${{env.QT_VERSION}}
        setup-python: false

If I used setup-python: true in the above YAML, then install-qt-action would override Python from 3.7 to 3.9, causing build errors later on because the dmgbuild package (installed by pip 3.7) wasn't found. This is why I used setup-python: false, which worked until today.

But since today it seems that using Python 3.7 breaks the installation of Qt. The solution is simply to install Qt first with setup-python: true (which sets Python to version 3.9), and only then manually setup Python to 3.7 and install pip dependencies:

    - name: Install Qt
      uses: jurplel/install-qt-action@v2
      with:
        version: ${{env.QT_VERSION}}
        setup-python: true

    - name: Setup Python
      uses: actions/setup-python@v2
      with:
        python-version: '3.7'
        architecture: 'x64'

    - name: Install python packages
      shell: bash
      working-directory: ${{runner.workspace}}
      run:
        pip3 install dmgbuild

Oh that's interesting, I wonder why now python 3.7 doesn't work? aqtinstall is meant to work with python 3.6 and higher. Well I'm glad you got it fixed regardless.

Hi
I'm facing the same problem with Linux targets.
And setup-python: false was not effective.
Are there the other workarounds?

Hi @akiyosi , you should actually try with setup-python: true, have you tried that? Here, aqtinstall is using Python 3.6, and by using setup-python: true it should bump the Python version and perhaps fix the problem.

If the rest of your build does depend on Python 3.6, you can roll it back to this version after the Qt Install step, like this:

    - name: Install Qt
      uses: jurplel/install-qt-action@v2
      with:
        version: ${{env.QT_VERSION}}
        setup-python: true

    - name: Setup Python
      uses: actions/setup-python@v2
      with:
        python-version: '3.6'
        architecture: 'x64'

[dalboris]

Relevant: https://github.com/miurahr/aqtinstall/releases/tag/v1.1.3

This is a new release of aqtinstall released 4 hours ago with the following changelog:

Fixed
-----

* Key error on 3.6.13, 3.7.10, 3.8.8, and 3.9.2(#221)

[dalboris]

In light of this new info, I'm reopening this issue. I think the proper course of action would be for install-qt-action to set the default aqtversion to v1.1.3.

In the meantime, @akiyosi and others, you could try something like that:

- name: Install Qt
      uses: jurplel/install-qt-action@v2
      with:
        version: '5.15.2'
        setup-python: true
        aqtversion: '>=1.1.3'

[dalboris]

Also see: miurahr/aqtinstall#221

[jurplel]

Will update aqtinstall asap

[jurplel]

done

[dalboris]

Thanks! I closed the issue, I suppose anyone should feel free to reopen if there are still issues about this.

@dalboris @jurplel
Thanks :D
