背景

笔者最近发现 github 的用户头像和自己文章中的图片显示不出来了。然后今天发现安装 homeBrew 和 nvm 出现了标题的报错信息。

image

以上是安装 pnpm 的报错信息，可以发现，脚本需要到 raw.githubusercontent.com 上拉取代码。

网上搜索了一下，发现是 github 的一些域名的 DNS 解析被污染，导致DNS 解析过程无法通过域名取得正确的IP地址。

DNS 污染

DNS 污染，感兴趣的朋友可以去了解一下。

解决方案

打开 https://www.ipaddress.com/ 输入访问不了的域名

image

查询之后可以获得正确的 IP 地址

在本机的 host 文件中添加，建议使用 switchhosts 方便 host 管理

199.232.68.133 raw.githubusercontent.com
199.232.68.133 user-images.githubusercontent.com
199.232.68.133 avatars2.githubusercontent.com
199.232.68.133 avatars1.githubusercontent.com

添加以上几条 host 配置，页面的图片展示就正常了，homebrew 也能装了，nvm 也行动灵活了。

如果是mac，配置了host文件后，下载速度会出现为0的情况，需要先执行xcode-select --install命令，再执行curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

感谢大佬。Mac用switchhosts无法写入host，可以参考这篇

改了hosts文件后还是不行，但是听了这位的建议后成功了，感谢

我通过修改 DNS 为 8.8.8.8 解决了这个问题。

笨方式是浏览器打开，然后复制文字，创建文件，粘贴，然后执行

安装network-manager：sudo apt-get install network-manager
重启网络：sudo systemctl restart NetworkManager

最后两步是关键
