Did the version of openssl change due to the construction of the python environment?
Error occurred because the version of OpenSSL referenced by ruby is gone Apparently there is no choice but to reinstall

==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/[email protected]/certs
and run
/usr/local/opt/[email protected]/bin/c_rehash
[email protected] is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.
If you need to have [email protected] first in your PATH run:
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> /Users/user/.bash_profile
For compilers to find [email protected] you may need to set:
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
For pkg-config to find [email protected] you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
