Installation Ubuntu 16.04（Xenial Xerus）中的角度安装失败

Angular CLI在运行安装命令时始终显示错误，

ng

显示未找到此类命令。我如何解决这个问题

我又跑了一次，现在我明白了：

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

据

PS：在linux上全局安装（

-g

参数）时，请不要忘记使用

sudo

，

我更改了它，但同样的问题再次出现。嗯，谢谢；请为您的帖子创建更新部分，以便打印新日志。我当前的回答确实符合您当前的情况，因此我建议您单独更新一节，谢谢。我注意到更新的错误日志显示您不再在命令前面使用

sudo

；这就是权限问题。我把它改为@angular，但仍然是同一个问题。嗨，请仔细阅读我的答案；您还需要使用

sudo

，否则会出现权限问题

sudo npm install -g @angular/cli
