Example repo for python/mypy#11334
A. Mypy works fine with -p and without --html-report:
$ poetry run mypy -p folder Success: no issues found in 4 source files
B. Mypy works fine with --html-report and without -p:
$ poetry run mypy folder --html-report=mypy-report Generated HTML report (via XSLT): /mnt/c/tmp/mypy-bug/mypy-report/index.html Success: no issues found in 3 source files

Note
|
In the real repo I cannot omit ldap_tool/commands/fetch_users.py:10: error: Skipping analyzing ".base": found module but no type hints or library stubs |
C. Mypy breaks when passed both -p and --html-report:
$ poetry run mypy -p folder --html-report=mypy-report /mnt/c/tmp/mypy-bug/folder/subfolder: error: INTERNAL ERROR -- Please try using mypy master on Github: https://mypy.readthedocs.io/en/stable/common_issues.html#using-a-development-mypy-build If this issue continues with mypy master, please report a bug at https://github.com/python/mypy/issues version: 0.910 /mnt/c/tmp/mypy-bug/folder/subfolder: : note: please use --show-traceback to print a traceback when reporting a bug Generated HTML report (via XSLT): /mnt/c/tmp/mypy-bug/mypy-report/index.html
