Azure-pipelines：没有名为“xmlrunner”的模块

Question

Stackoverflow 中的 Azure Pipelines 问题似乎有很多“没有模块名称...”...现在，由于它们都没有帮助我，轮到我了:(

这是我正在尝试运行的管道：一个简单的CI 测试我的 Django 应用程序，基于 Microsoft 自己的模板：

trigger:
- master

pool:
  vmImage: ubuntu-latest
strategy:
  matrix:
    Python310:
      PYTHON_VERSION: '3.10'
  maxParallel: 2

steps:
- task: UsePythonVersion@0
  inputs:
    versionSpec: '$(PYTHON_VERSION)'
    architecture: 'x64'

- task: DownloadSecureFile@1
  name: dotEnv
  inputs:
    secureFile: 'uploaded.env'

- task: PythonScript@0
  displayName: 'Export project path'
  inputs:
    scriptSource: 'inline'
    script: |
      """Search all subdirectories for `manage.py`."""
      from glob import iglob
      from os import path
      # Python >= 3.5
      manage_py = next(iglob(path.join('**', 'manage.py'), recursive=True), None)
      if not manage_py:
          raise SystemExit('Could not find a Django project')
      project_location = path.dirname(path.abspath(manage_py))
      print('Found Django project in', project_location)
      print('##vso[task.setvariable variable=projectRoot]{}'.format(project_location))

- task: CopyFiles@2
  displayName: 'Add .env file'
  inputs:
    SourceFolder: '$(Agent.TempDirectory)'
    Contents: 'uploaded.env'
    TargetFolder: '$(projectRoot)'
  
- script: mv uploaded.env .env
  displayName: 'Rename .env file'

- script: |
    python -m pip install --upgrade pip setuptools wheel
    python -m pip install poetry
    python -m pip install unittest-xml-reporting xmlrunner
    poetry install
  displayName: 'Install dependencies'

- script: |
    pushd '$(projectRoot)'
    poetry run python manage.py test --testrunner xmlrunner.extra.djangotestrunner.XMLTestRunner --no-input
    poetry run coverage xml
  displayName: 'Run tests'

- task: PublishTestResults@2
  inputs:
    testResultsFiles: "**/TEST-*.xml"
    testRunTitle: 'Python $(PYTHON_VERSION)'
  condition: succeededOrFailed()

- task: PublishCodeCoverageResults@1
  inputs:
     codeCoverageTool: Cobertura
     summaryFileLocation: 'coverage.xml'
     reportDirectory: 'htmlcov'
  displayName: 'Publish Coverage Results'

这在测试阶段失败，并出现错误： ModuleNotFoundError: No module named 'xmlrunner'

对我来说最奇怪的是我看到xmlrunner 在前面的步骤中安装：

以前有人遇到过这种情况吗？

编辑：我最近遇到了同样的问题当我的时候出现了不同的问题。迁移到 Poetry 和 Python 3.10，因此两者之一可能是罪魁祸首。

您正在 pip 安装 xmlrunner 和 unittest-xml-reporting，但您可能想要的只是 unittest-xml-reporting。 xmlrunner 是另一个 PyPi 库。
