Why ModuleNotFoundError occurs when trying to run script with PyPy3?

Question

I have a Python script which runs perfectly with CPython (under virtualenv), unfortunately throws ModuleNotFoundError error when I run it with PyPy3 (under virtualenv).

My package is parser and I import Analyze with from parser.Analyze import Analyze . There is parser directory under the same directory with my script. And parser directory has __init__.py file in it too.

Should I do something special for PyPy?

Answer 1

On both PyPy and CPython parser is a built-in module. Can you see if the problem is that the built-in is masking your package? You can rename it to something like myparser . PyPy tracks issues at https://bitbucket.org/pypy/pypy/issues or you can reach out on IRC at #pypy
