FileNotFound 错误为什么在 azure 上使用 testenv py38 运行 tox

如何解决FileNotFound 错误为什么在 azure 上使用 testenv py38 运行 tox

我有一个使用 azure yaml 管道部署的 Python 代码库。我们正在尝试从 python 3.6 迁移到 3.8。当我尝试在 py38 testenv 中运行 tox 时，出现一个奇怪的错误：

       cwd: C:\a\4\s\pip-req-build-5_140xzf
  Complete output (8 lines):
  Traceback (most recent call last):
    File "C:\a\4\s\.tox\py38\lib\site-packages\pip\_vendor\pep517\_in_process.py",line 280,in <module>

  FileNotFoundError: [Errno 2] No such file or directory: '.\\tmpirazvq1d\\input.json'

WARNING: You are using pip version 20.2.3; however,version 21.1.2 is available.
You should consider upgrading via the 'C:\a\4\s\.tox\py38\Scripts\python.EXE -m pip install --upgrade pip' command.

我已经升级了 pip，但我猜测 testenv 会下载并使用自己的 pip 并覆盖我的。这些是产生此错误的管道任务：

- powershell: |
    write-host "Upgrade pip";
    python -m pip install --upgrade pip --no-cache-dir;

    write-host "Install tox";
    pip install tox tox-venv --upgrade --no-cache-dir;
  displayName: 'Install tox'

- powershell: |
    python -m pip install --upgrade pip;
    write-host "Running tox with --recreate argument.";
    tox -r;
  displayName: 'Run tox'

这是我的 tox.ini 文件的相关部分：

有没有人处理过这个问题，或者谁能指出我正确的方向？
