Python ошибка virtualenv при попытке настроить сервер Matrix Synapse

Question

Я следую этому руководству , чтобы попытаться настроить домашний сервер Matrix Synapse.

Однако я сталкиваюсь с этой ошибкой: The 'zipp>=0.4' distribution was not found and is required by importlib-resources при попытке запустить virtualenv

Я предпринял следующие шаги:

brew install python
macbook@Macbook-MBP ~ % python --version
Python 3.7.7
macbook@Macbook-MBP ~ % virtualenv
Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 3241, in <module>
    @_call_aside
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 3225, in _call_aside
    f(*args, **kwargs)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 3254, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 585, in _build_master
    return cls._build_from_requirements(__requires__)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 598, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources/__init__.py", line 786, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'zipp>=0.4' distribution was not found and is required by importlib-resources

Как я могу устранить эту ошибку? Я на macOS Каталина 10.15.
