一、报错内容
今天在安装nvm的时候
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
遇到了这样的错误：
curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

二、问题原因
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。
什么是DNS污染？🤔
三、解决办法
1. 第一步：获取正确的IP地址
打开 https://www.ipaddress.com/ 输入访问不了的域名

2. 第二步：修改hosts
① 获取到正确的IP地址后，在终端输入：
$ sudo vim /etc/hosts
② 在hosts中加入以下内容：
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
