I get this error:
Could not install packages due to an EnvironmentError: Could not find a suitable TLS CA certificate bundle, invalid path: /home/yosr
If you're on Mac (mine is 10.13.6), use the following command:
(security find-certificate -a -p ls /System/Library/Keychains/SystemRootCertificates.keychain && security find-certificate -a -p ls /Library/Keychains/System.keychain) > $HOME/.mac-ca-roots
Then do modify .bashrc with
export REQUESTS_CA_BUNDLE="$HOME/.mac-ca-roots"
Then do
$ source ~/.bashrc
