I have issue installing squib dependence 'cairo'

[felipefernandes]

I've tried install squib, however I got this error message "Failed to run 'brew install cairo'." I also tried to install over brew but it not worked as well.

When I ran brew install cairo, I got another error:

Pruned 1 symbolic links and 4 directories from /usr/local
==> Caveats
==> openssl
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

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.

If you need to have openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

I am unfortunately no Ruby or Squibs expert. Have you looked at the official Squibs documentation? https://squib.readthedocs.io/en/v0.14.0/install.html
