Error when importing ssl in Python 3.7.4 on macOS 10.14.6


Why am I getting an error when trying to import ssl in python3 ?

Python 3.7.4 (default, Jul  9 2019, 18:13:23) 
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ImportError: dlopen(/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload/_ssl.cpython-37m-darwin.so, 2): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib

I am having a hard time installing packages via pip which seem to be throwing an SSL error.


Solution

  • I had exactly the same problem, which was solved once I upgraded my Python version to 3.7.6 using brew.

    brew upgrade python3
    

    This threw a permission denied error, but the update was done nonetheless, after which I was able to import ssl:

    Python 3.7.6 (default, Dec 30 2019, 19:38:28) 
    [Clang 11.0.0 (clang-1100.0.33.16)] on darwin

    >>> import ssl
    >>> ssl
    <module 'ssl' from '/usr/local/Cellar/python/3.7.6_1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/ssl.py'>
    >>>
