在Windows下安装了Rust成功，但是 Cargo new 的时候，出现了以下问题：

C:\Users\Administrator\Desktop>cargo new hello error: Failed to create package hello at C:\Users\Administrator\Desktop\hello

Caused by: could not load Cargo configuration

Caused by: could not parse TOML configuration in C:\Users\Administrator\.cargo\config

Caused by: could not parse input as TOML

Caused by: redefinition of table source.crates-io for key source.crates-io at line 10 column 1

Cargo -V的版本是：cargo 1.50.0 (f04e7fab7 2021-02-04)，搜了很久没找到答案，请帮忙下，谢谢！
