简介： curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

就是网址不对。怎么办？


查找IP

打开网站https://www.ipaddress.com。打不开？那阁下看看其他博文怎么说的。


输入raw.githubusercontent.com，看到当前IP。


修改文件

打开/etc/hosts，输入以下内容（185.199.108.133就是刚刚查询到的IP）。


185.199.108.133 raw.githubusercontent.com


再次尝试

curl -O https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc
