Ubuntu 16.04（Xenial Xerus）中的角度安装失败

Question

Angular CLI 在运行安装命令时总是显示错误，而且ng 显示找不到这样的命令。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!

npm ERR! fatal: Could not read from remote repository.
npm ERR!
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.

shivashish-Inspiron-3521% ng new app
zsh: command not found: ng
shivashish-Inspiron-3521% node -v
v8.13.0

我再次运行，现在我得到了这个：

shivashish-Inspiron-3521% npm install -g @angular/cli
npm WARN checkPermissions Missing write access to /usr/lib/node_modules

Answer 1

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Step 1: Install the Angular CLI

PS：在linux

上全局安装（-g参数）时请不要忘记使用sudo
