如何解决已尝试重装仍出现的‘ModuleNotFoundError: No module named 'requests'’？

It sounds like you’ve already tried the basic uninstall/reinstall for requests, but the error persists—let’s dig into why this might be happening and fix it step by step.

First, let’s recap what you’ve shared (from your command output):

(C:\Users\user\Anaconda3) C:\Users\user>Desktop\receipt.py
Traceback (most recent call last):
File "C:\Users\user\Desktop\receipt.py", line 8, in
import requests
ModuleNotFoundError: No module named 'requests'

(C:\Users\user\Anaconda3) C:\Users\user>pip uninstall requests
Uninstalling requests-2.18.4:
Would remove:
c:\users\user\anaconda3\lib\site-packages\requests-2.18.4.dist-info*
c:\users\user\anaconda3\lib\site-...

Common Causes & Fixes #

• Ensure you’re installing to the right Python environment
  Sometimes your system has multiple Python versions, and pip might be pointing to a different one than the one running your script. Instead of using plain pip, run this to guarantee you’re using the Anaconda environment’s pip:

  python -m pip install requests
  

  To verify alignment, check the paths of your Python and pip executables:

  # On Windows
  where python
  where pip
  

  Both should show paths inside C:\Users\user\Anaconda3\.

• Force a clean reinstall (skip cache)
  Corrupted cache files can mess up installations. Run this to completely refresh your requests installation without using cached files:

  pip install --force-reinstall --no-cache-dir requests
  

• Confirm your script is using the Anaconda Python
  Even if your command line shows the Anaconda environment, your script might be running with a different interpreter. Add these lines at the top of receipt.py and run it again:

  import sys
  print("Python executable path:", sys.executable)
  

  If the output isn’t C:\Users\user\Anaconda3\python.exe, you need to adjust your IDE or run settings to use the Anaconda Python interpreter.

• Check for permission issues
  Sometimes Windows restricts installations to user-specific system folders. Try running your command prompt as Administrator, then reinstall requests with pip install requests.

Let me know if any of these steps resolve the issue for you!
