Custom `install_command` is not run on GitHub Actions

[tbrlpld]

Describe the bug

The custom install_command from tox.ini seems to be ignored.

If my command depends on packages that should be installed with the install_command I get errors when running on GitHub Actions, but not locally.

To Reproduce

• GitHub Actions configuration

  
  name: Laces CI

on: push: branches:

• main

• 'stable/**'

  pull_request:

concurrency: group: ${{ github.workflow }}-${{ github.ref }} cancel-in-progress: true

permissions: contents: read # to fetch code (actions/checkout)

jobs: lint: runs-on: ubuntu-latest steps:

• uses: actions/checkout@v3 with: fetch-depth: 0
• name: Set up Python 3.8 uses: actions/setup-python@v4 with: python-version: '3.8'

• uses: pre-commit/action@v3.0.0

  test-sqlite: runs-on: ubuntu-latest needs: lint strategy: matrix: python: ['3.8', '3.9', '3.10', '3.11']

  steps:

• uses: actions/checkout@v3
• name: Set up Python ${{ matrix.python }} uses: actions/setup-python@v4 with: python-version: ${{ matrix.python }}
• name: Install run: | python -m pip install --upgrade pip setuptools wheel python -m pip install .[ci]
• name: Test run: tox -vv env: DB: sqlite
• name: Upload coverage reports to Codecov uses: codecov/codecov-action@v3 env: CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }} with: files: ./.coverage.json

* tox and tox-gh-actions configuration

* Link to the GitHub Actions job if a repository is public:
  * Here is a run that failed: https://github.com/tbrlpld/laces/actions/runs/7604822530/job/20708230969#step:5:113
  * The failing dependency is `coverage`. 
  * I can also not see any logging of the install step, which makes this hard to debug. I am already running with `tox -vv`.

**Expected behavior**

The custom install command should be used to install the dependencies. 

**Additional context**

* tox: 4.11.3
* tox-gh-actions: 3.13
