Installation Issues

setuptools is too old

Problem: error in scf setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers
Solution: pip install -U setuptools

The existing distutils installation package cannot be upgraded

Problem: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Solution: pip install -I PyYAML==x.x.x (view the specific version in requirements.txt)

six is too old

Problem: pip "Cannot uninstall 'six'. It is a distutils installed project..."
Solution: sudo pip install six --upgrade --ignore-installed six

pytz is too old

Problem: uninstalling pytz : [error 1] Operation not permitted ...
Solution: sudo pip install pytz --upgrade --ignore-installed six

Usage Issues

How do I specify a function for local debugging if the YAML configuration file contains multiple function descriptions?

Problem: Error: You must provide a function identifier (function's Logical ID in the template). Possible options in your template: ['xxxB', 'xxxA']
Solution: include the function name when running the local invoke command, such as scf local invoke -t template.yaml xxxA

The [SSL: CERTIFICATE_VERIFY_FAILED] error occurred during deployment

Problem: when deploy was used, function deployment failed with error message [SSL: CERTIFICATE_VERIFY_FAILED]
Cause: in macOS 10.12 + Python 3.6 and higher versions, Python no longer reads certificates from the system path, resulting in certificate reading failures, and SSL verification will fail when TencentCloud API is called for deployment
Solution: in the Python installation directory, run the Install Certificates.command script to install the certifi package automatically.
