Run the following command :
pip config set global.cert "C:\ProgramData\NetFree\CA\netfree-ca-bundle-curl.crt"
Note: This command should only be run if you are on Windows and have already installed Security Certificate Software. In a different case, the certificate must be downloaded to the computer from here, extracted and run the command with the path change according to the location where you saved the certificate on the computer.
More options: Adding a parameter that points to the certificate location in each command execution, or adding the certificate location in the software settings file, or canceling the security check, see here.
