Azure Web App部署报错：No module named 'pip'求助

I’ve run into this exact issue before—suddenly a deployment that worked fine hours ago breaks with a missing pip error. Here are the most reliable fixes to get your deployment back on track:

• Force a fresh virtual environment rebuild
  Azure often caches existing virtual environments, and sometimes the cached env gets corrupted (including losing pip). Create a .deployment file in your project root with this content:

  [config]
  SCM_BUILD_ARGS = --no-cache
  

  This tells the deployment process to discard the cached environment and build a new one from scratch, which will reinstall pip and all your dependencies properly.

• Upgrade to a supported Python version
  Looking at your error log, you’re using Python 3.4—this version reached end-of-life years ago, and Azure’s older Python images can have broken or missing pip components. To fix this:

  • Add python_version >= 3.7 at the top of your requirements.txt
  • Or create a .python-version file in your root with a supported version (e.g., 3.9)
    Using a maintained Python version will avoid these outdated dependency issues long-term.

• Clear deployment cache manually
  Head to the Azure Portal for your Web App:

  1. Go to Deployment Center > Advanced Options
  2. Click Reset deployment credentials
  3. Alternatively, open the Kudu console (your app's scm site: https://<your-app-name>.scm.azurewebsites.net/), navigate to D:\home\site\wwwroot\env, delete the entire env folder, then re-push your code.

• Manually install pip in your deployment script
  If the above steps don’t work, you can force pip installation during deployment. Create a deploy.sh file in your project root:

  python -m ensurepip --upgrade
  pip install -r requirements.txt
  

  Then update your .deployment file to use this script:

  [config]
  command = deploy.sh
  

This sudden failure usually happens because Azure’s backend updated its cached Python images, or your existing virtual environment became corrupted. Ditching the outdated Python 3.4 will prevent most recurrence of this issue.
