正常下载安装ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

requests 2.25.0 requires idna<3,>=2.5, but you'll have idna 3.1 which is incompatible.
