error request to xxx failed, reason: connect ECONNREFUSED 0.0.0.0:443

今天升级React-Native到0.70+报错，错误日志如下：

npx react-native upgrade 0.70.7                   
info Fetching diff between v0.69.7 and v0.70.7...
error request to https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/0.69.7..0.70.7.diff failed, reason: connect ECONNREFUSED 0.0.0.0:443
error Failed to fetch diff for react-native@0.70.7. Maybe it's not released yet?
info For available releases to diff see: https://github.com/react-native-community/rn-diff-purge#diff-table-full-table-here

倒腾了大半天，记录一下解决方案吧，希望能帮助到遇到同样问题的同学。

• 导致错误的原因

找不到 raw.githubusercontent.com

• 解决方案

通过 www.ipaddress.com/ 查询 raw.githubusercontent.com 的IP，并在hosts中配置

185.199.108.133 raw.githubusercontent.com

• 补充说明

// 这个是我查询到的，我只添加了其中的一个IP，这些IP都是都是可以解析到「raw.githubusercontent.com」的
