判断问题

尝试访问https://pypi.tuna.tsinghua.edu.cn/simple/platformio/成功

点击文件后报错如下：

解决问题- 换源 （ Windows下有两个地方需要更改）

cmd命令行

C:\Users\Administrator>npm get registry
C:\Users\Administrator>npm config set registry http://mirrors.aliyun.com/pypi/simple/

Pip文件

文件路径：C:\Users\（你的用户名）\AppData\Roaming\pip

文件名字 pip.ini (如果没有可以自行创建)

[global]
index-url=http://mirrors.aliyun.com/pypi/simple/
[install]
use-mirrors=true
mirrors=http://mirrors.aliyun.com/pypi/simple/
trusted-host=mirrors.aliyun.com

总结：最终还是回到换源上，删除重装都没用。
