When following the quickstart UWSGI guide and attempting to start the server, the following error occurs:
ImportError: dlopen(/Users/xxxxxxxx/anaconda3/lib/python3.7/lib-dynload/_struct.cpython-37m-darwin.so, 2): Symbol not found: _PyByteArray_Type
Referenced from: /Users/xxxxxxxx/anaconda3/lib/python3.7/lib-dynload/_struct.cpython-37m-darwin.so
Expected in: flat namespace
Some things I've tried:
- Reinstalling UWSGI -
pip install --upgrade --force-reinstall --no-binary :all: --no-cache-dir uWSGI==2.0.17 - Reinstalling anaconda
Clues:
- The application will will run properly using the werkzeug development sever w/ no errors.
- Running
from struct import pack, unpackin the~/anaconda3/bin/pythoninterpreter does not cause an error - Both '~/anaconda3/bin/python3' and '/Users/xxxxxxxx/anaconda3/bin/uwsgi' contain the symbol (nm
/Users/xxxxxxxx/anaconda3/bin/uwsgi | grep _PyByteArray_Type)
How can I fix this problem? If this is a novel issue, where should I report it? Is it a problem with how Conda compiled Python? UWSGI?
System:
- OS: OSX 10.15.2
- Conda: 4.7.12
- UWSGI: 2.0.18
- Architecture: x86_64
