Bug Report

If the first 2 entries of sys.path are pwd, mypy seems to miss type checks in imported modules.

To Reproduce

mypy==0.971

# sscce.py import sys import mypy.api sys.path.insert(0, sys.path[0]) print(mypy.api.run(["good.py"])[0])

# good.py import bad

# bad.py  foo: str = 5

Expected Behavior

bad.py:1: error: Incompatible types in assignment (expression has type "int", variable has type "str") Found 1 error in 1 file (checked 1 source file) 

Actual Behavior

Success: no issues found in 1 source file 

Your Environment

• Mypy version used: 0.971

This issue broke pytest-mypy tests which use pytester.runpytest_subprocess to run pytest in a subprocess (see realpython/pytest-mypy#139).
