pip problem

[didi226]

When I use "pip install -i https://test.pypi.org/simple/ tllib==0.4" 出现问题ERROR: Could not find a version that satisfies the requirement webcolors (from tllib) (from versions: none) ERROR: No matching distribution found for webcolors python==3.9的版本可以正常的安装 python==3.10的版本存在这个问题。

It's seems like the pip cannot get package from https://test.pypi.org/simple/. I use pip install -i https://test.pypi.org/simple/ tllib==0.4 --extra-index-url https://pypi.tuna.tsinghua.edu.cn/simple and it works.

Thanks for your advice!
