Python crashing on MacOS 10.15 Beta (19A582a) with

Question

I ran my Django project with new macOS Catalina and was running fine.
I installed oh_my_zsh then I tried to run the same project it is crashing with the following errors. I uninstalled oh_my_zsh and tried again but it did not worked.

Answer 1

r.xuan from this Apple Dev thread identified the steps of a workaround for the error Invalid dylib load. Clients should not load the unversioned libcrypto dylib as it does not have a stable ABI. by replacing the libssl.dylib and libcrypto.dylib links in /usr/local/lib with links to libs from Homebrew's install of openssl.

The steps are:

Get fresh libs

1) brew update && brew upgrade && brew install openssl

2) cd /usr/local/Cellar/openssl/1.0.2t/lib

3) sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib/

Backup the old ones

4) cd /usr/local/lib

5) mv libssl.dylib libssl_bak.dylib

6) mv libcrypto.dylib libcrypto_bak.dylib

Create new links

7) sudo ln -s libssl.1.0.0.dylib libssl.dylib

8) sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib

Answer 2

For me it was enough to re-install Python's cryptography package.

pip uninstall cryptography
pip install cryptography

Answer 3

Try:

python3 -m pip install oscrypto

Worked for me!

Answer 4

I just came across the same problem and felt a bit uncomfortable to manually link things around.

I was able to solve the problem by simply

1. Installing openssl via homebrew:

   brew install openssl
   

2. Pointing towards the dynamic libraries from openssl via DYLD_LIBRARY_PATH:

   export DYLD_LIBRARY_PATH=/usr/local/opt/openssl/lib:$DYLD_LIBRARY_PATH
   

I've just added that line to my .zshrc.

Edit: According to this question, the usage of DYLD_FALLBACK_LIBRARY_PATH might be preferable over DYLD_LIBRARY_PATH.

Answer 5

Caveat: I am not a security expert, and this solution messes with crypto libraries!

I don't think your issue stems from zsh or oh-my-zsh. My best guess: some crypto libraries installed with MacOS 10.15 are incompatible with Homebrew's python3 installation.

Here's what fixed the issue for me

# Install openssl via homebrew.
# Note: According to homebrew, "openssl is keg-only, which means it was
# not symlinked into /usr/local, because Apple has deprecated use of
# OpenSSL in favor of its own TLS and crypto libraries."
brew install openssl
# Symlink those versions into /usr/local/lib, which gets Python to dynamically
# link against those instead of the version in /usr/lib/.
# Got the idea from https://forums.developer.apple.com/thread/119429
cd /usr/local/lib
sudo ln -s /usr/local/Cellar/openssl/1.0.2t/lib/libssl.1.0.0.dylib libssl.dylib
sudo ln -s /usr/local/Cellar/openssl/1.0.2t/lib/libcrypto.1.0.0.dylib libcrypto.dylib

My situation for context:

• Recently upgraded to MacOS 10.15
• I use python/pip installed via homebrew: brew install python
• pip3 was failing with SIGABRT

Answer 6

It must be usage of some dependencies like cryptography

Solution:

cd your-site-packages-path/
vim ./asn1crypto/_int.py

find this line; delete it, and everything is ok

# from ._perf._big_num_ctypes import libcrypto
