一、npm更换镜像源的方法

输入命令如下：

npm config set registry 要更换的镜像源地址
npm config set registry https://npm.aliyun.com	# 更换为阿里云npm镜像源
1
2

如公司只能用内网镜像源，则将地址更换为公司镜像源的地址

二、ubuntu更换镜像源的方法

1.输入命令lsb_release -c查看ubuntu的Codename版本，这个很重要，ubuntu的Codename版本有focal、bionic等，这点很重要，很多网上教程都没有写这点，所以很多人更换错了镜像源才不起作用

$ lsb_release -c
Codename: focal
1
2

2.为安全起见，备份原文件sources.list

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
1

3.将sources.list原有内容删掉或全部注释掉，填入对应ubuntu的Codename版本的镜像源地址
如下为阿里云的ubuntu的focal版本，如你的ubuntu的Codename版本为bionic，则把focal改成bionic就好

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

# 预发布软件源，可注释掉
# deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

清华源：
