从管道将Python应用程序部署到Azure Web应用程序，不包括需求包

我有一个PythonFlask 应用程序，我想将其部署到Azure Web应用程序.

For some reason the venv that gets created during the build is not keeping the packages that get installed and I don't understand why. As an example, the requirements.txt has openai==1.12.0 in it.
The build job prints Successfully installed [...] openai-1.12.0 [...]. That sounds like it should be fine.

然后，部署成功后，我在Web应用程序的Azure shell中运行pip list(antenv虚拟环境处于活动状态)以查看已安装的内容并获得没有openai的列表.如果我列出venv文件夹的内容，它将包含我想要安装的所有包.

这是构建作业(job)的yaml:

          - script: |
              sudo apt-get install python3.11-dev portaudio19-dev
              ls
              python -m venv antenv
              source antenv/bin/activate
              python -m pip install --upgrade pip
              pip install -r ./requirements.txt
            workingDirectory: "$(projectRoot)"
            displayName: "Install requirements"

I also tried to change the pip install line to
pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt
with no luck, the packages are in that folder but not in use by the venv.
Am I doing anything obviously wrong? Any tips?

编辑: 这是我完成pip install步后的pip list分:
