angular-cli使用问题记

一、解决被墙的问题

方法1：设置代理

npm config set proxy=http://127.0.0.1:6152

npm config set https_proxy=http://127.0.0.1:6152

查看刚刚设置的代理

npm config list

删除刚刚配置的代理

npm config delete proxy

npm config delete proxy

方法2、安装nrm切换源

npm install -g nrm

nrm use cnpm 则切换成了cnpm的源

方法3、安装cnpm

npm install -g cnpm

使用cnpm install xxx进行安装

二、安装angular-cli

安装最新版本的cli

npm install -g @angular/cli@latest

查看版本

ng -v

我在这里安装的时候没有报错，在运行此命令的时候报了个错，如下：

Cannot read property 'set' of null

TypeError: Cannot read property 'set' of null

原因：我是在一个已经通过上个版本angular-cli生成的项目里运行这个的，坑啊，坑了我好久

三、升级angular-cli

npm uninstall -g @angular/cli

npm cache clean

npm install -g @angular/cli@latest

四、将ng设置成使用cnpm

ng set --global packageManager=cnpm
