Angular CLI在运行安装命令时总是显示错误，而且ng显示未找到此类命令。我该如何解决这个问题？
shivashish-Inspiron-3521% cd Angular-project shivashish-Inspiron-3521% ls shivashish-Inspiron-3521% sudo npm install -g angular/cli npm ERR! Error while executing: npm ERR! /usr/bin/git ls-remote -h -t ssh://git@github.com/angular/cli.git npm ERR! npm ERR!

我再次运行，现在我得到了这个：
shivashish-Inspiron-3521% npm install -g @angular/cli

这是因为它应该是@angular/cli而不是angular/cli。正确的命令是：
sudo npm install -g @angular/cli
根据步骤1：安装Angular CLI
PS：请不要忘记在linux上全局安装时使用sudo(-g参数(
