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"' >> ~/.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"

Python has been installed as
  /usr/local/opt/[email protected]/bin/python3

You can install Python packages with
  /usr/local/opt/[email protected]/bin/pip3 install <package>
They will install into the site-package directory
  /usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have [email protected] first in your PATH run:

You will need to codesign the binary. For instructions, see:
