Django 2中manage.py文件语法错误求助

Hey there! Let's figure out why that from exc line is throwing a syntax error even though you haven't touched the original code. Since you've already checked brackets, quotes, and indentation, let's dive into the less obvious culprits:

• Hidden malformed characters from file transfer
  When dragging files into Sublime Text, invisible special characters (like non-ASCII spaces, broken line endings, or control characters) can sneak in. These don't show up in normal view but break Python's syntax parser.
  Fix this by:

  1. In Sublime, go to View > Show Invisible Characters to reveal any weird symbols around the from exc line. Delete them if you spot any.
  2. Re-copy the exact line from the original Django 2.0 file in your virtual environment (don't rely on the dragged version) and paste it over the problematic line.

• Incorrect file encoding
  If the file was saved with a non-UTF-8 encoding, Python might misinterpret parts of the code. In Sublime, go to File > Save with Encoding > UTF-8 to ensure the file uses the standard Python-compatible encoding.

• Accidental subtle changes during drag-and-drop
  It's easy for a tiny detail to get altered without noticing (like a missing dot for relative imports, e.g., from .exc instead of from exc). Double-check that the line matches the exact original code from your Django virtual environment—compare side-by-side if needed.

• Virtual environment mismatch (long shot)
  While syntax errors are usually code-related, confirm you're running the correct virtual environment:

  • Activate your Django 2.0 venv, then run python --version and pip show django to verify the versions match what you expect.

Give these steps a try—odds are the issue is with hidden characters or a subtle formatting glitch from the file drag.
