手动安装rorolite包后Python提示ModuleNotFoundError求助

Hey, let's work through this ModuleNotFoundError step by step—there are a few common reasons this happens even when you've placed the package in your Python 3.6 site-packages directory:

1. Fix the folder structure in site-packages #

When you download a package from PyPI, the zip file usually includes an outer folder (like rorolite-1.2.3 with a version number) that wraps the actual rorolite module folder. If you just dropped that outer folder into site-packages, Python won't recognize it as a valid importable module.

• Navigate to Python3.6\Lib\site-packages
• Make sure there’s a direct rorolite folder here (not nested inside another version-named folder)
• If it’s nested, open the extracted zip, grab the inner rorolite folder, and move it directly into site-packages

2. Confirm you’re using the right Python interpreter #

It’s really common to have multiple Python versions installed on Windows, and your IDE or command line might be pointing to a different one than Python 3.6.

• Add these lines to the top of your test script and run it:

  import sys
  print(sys.executable)
  print(sys.path)
  

• The first output line shows which Python interpreter is running. Make sure it matches your Python3.6\python.exe path
• The sys.path list should include your Python3.6\Lib\site-packages directory. If it doesn’t, you’re using the wrong Python instance

3. Check for an __init__.py file #

Most Python packages need an __init__.py file (even an empty one) to mark a folder as an importable module.

• Open the rorolite folder in site-packages
• If there’s no __init__.py file, create a blank text file, rename it to __init__.py, and save it in that folder

4. Clear Python’s module cache #

Python caches modules to speed up imports, and old cache files can sometimes cause unexpected issues.

• Close your IDE or command prompt completely, then reopen it and try importing rorolite again
• Alternatively, delete any __pycache__ folders inside the rorolite directory

5. Rule out Windows permission issues #

Occasionally, Windows file permissions can block Python from reading files in site-packages.

• Try running your script or Python interpreter as an administrator (right-click > "Run as administrator")
• Double-check that the rorolite folder and its files aren’t marked as "Read-only"

After trying these steps, your import rorolite should work as expected.
