SyntaxError: invalid character when running in Windows

Describe the bug

Tried this out today for the first time on a Windows machine, with a very simple repo that is using a requirements.txt but deptry throws an error- seems to trigger from a black related site package in lib:

Thanks for raising the issue @seandearnaley.

I assume your working directory is scrapestrike\. It seems deptry is also scanning files within scrapestrike/Lib/site-packages to determine if there are issues with your project's dependencies, which is probably not what you want.

Try running

deptry . -ee Lib

or adding Lib to the extend_exclude argument in your [tool.deptry] section in pyproject.toml.

For more information, see this section of the documentation.

Hope this helps!

Closing, since I assume the issue has been resolved. If not, please let me know and I'll reopen the issue.
