问题
I just upgraded my MacBook to Catalina v10.15.1. When executing my python script which only does one thing, imports pysftp, I get the following output:
WARNING: Executing a script that is loading libcrypto in an unsafe way. This will fail in a future version of macOS. Set the LIBRESSL_REDIRECT_STUB_ABORT=1 in the environment to force this into an error.
Could somebody shed some light on why this is occurring? Thank you.
