python certificate verify failed on MacOS

gistfile1.txt

# in case you have problems accessing servers over https using libraries like
# requests due to the failed certificate validation and you're 100% sure that
# those certs work for the rest of your software, you need to combine whatever
# you have in your Keychain and tell your python where to look for this bundled
# file. tested on the pyenv environment.

# export system root certs
security export -t certs -f pemseq -k /System/Library/Keychains/SystemRootCertificates.keychain -o bundleCA.pem

# export self-signed certs
security export -t certs -f pemseq -k /Library/Keychains/System.keychain -o selfSignedCAbundle.pem

# make one fat cert
cat bundleCA.pem selfSignedCAbundle.pem >> allCAbundle.pem

# now you should be able to export several env variables and be good
CERT_PATH=$(pwd)/allCAbundle.pem

export REQUESTS_CA_BUNDLE=${CERT_PATH}
