使用Pipenv安装Django遇异常：日志显示成功仍报错

Hey there, let's unpack this tricky issue you're facing—even though the install log says everything worked, something's clearly off with your Django setup. Let's walk through practical fixes step by step:

First, let's rule out the most common oversight:

• Confirm you're working inside the Pipenv virtual environment
  It's easy to forget to activate the shell and end up checking your global Python instead. Try either:

  # Activate the shell first
  pipenv shell
  django-admin --version
  

  Or skip the shell and run directly through Pipenv:

  pipenv run django-admin --version
  

  If this returns a Django version (like 2.0.3), the install actually succeeded—you just weren't checking the right environment!

Next, verify Pipenv's configuration files:

• Check your Pipfile and Pipfile.lock
  Open your project's Pipfile and look under the [packages] section. You should see entries like:

  django = "==2.0.3"
  pytz = "==2018.3"
  

  If these lines are missing, the install didn't properly register with Pipenv. Do the same check for Pipfile.lock—search for "django" to confirm it's listed with the correct version.

If those check out, try these targeted fixes:

• Clear Pipenv's cache and do a fresh install
  Corrupted cached packages can cause false "success" messages. Wipe the cache and reinstall with:

  pipenv install django --clear
  

• Ensure Pipenv uses your intended Python version
  Even if you switched system Python versions, Pipenv might still be tied to an old virtual environment. Check which Python your environment uses:

  pipenv --py
  

  If it's not 3.5 or 3.6.4, create a new environment with the specific version:

  pipenv --python 3.6.4
  pipenv install django
  

• Get verbose install logs
  The default log might hide subtle errors. Run the install with verbose output to see the full process:

  pipenv install django --verbose
  

  Look for any warnings, skipped steps, or error messages that didn't show up in the default log.

• Test Django import directly
  Activate the shell and run this command to test if Django is actually installed in the environment:

  pipenv shell
  python -c "import django; print(django.__version__)"
  

  If this throws an ImportError, the error message here will point you to the root cause—like missing dependencies or a version mismatch.

Let me know which step helps you track down the issue!
