Python Azure Function 即使在前面的步骤中安装也找不到模块

Question

我正在尝试创建一个 python azure 函数 CI 管道构建。在yml文件中，安装依赖项后（pytest存在于requirements.txt中），找不到pytest模块。我似乎无法弄清楚问题是什么。我错过了什么？

  - task: UsePythonVersion@0
    displayName: Use Python 3.11
    inputs:
      versionSpec: 3.11
  - task: Bash@3
    displayName: Install Application Dependencies
    inputs:
      targetType: inline
      script: >-
        python -m pip install --upgrade pip

        pip install --target="$(System.DefaultWorkingDirectory)/.python_packages/lib/site-packages" -r requirements.txt
  - script:  pytest . --verbose

Azure DevOps 在 pytest 步骤上失败，提示无法找到 pytest。

requirements.txt

pytest~=8.1.1

我尝试过的：

• 添加--target（如你所见）
• 将目标：主机添加到 pytest 脚本
• venv（有效，但我不想使用 venv）

Answer 1

我尝试在我的requirements.txt中添加

pytest

模块并运行下面的Azure Devops yaml管道，函数和包已成功部署。

我的 Azure DevOps 管道：-

trigger:
- main

  azureSubscription: '3xxxxxxxxxxx1a81b0e'

    steps:
    - bash: |
        if [ -f extensions.csproj ]
        then

    strategy:
      runOnce:

          steps:
