Answer 1

如果你按照this site中提到的指令，你会发现命令

npm install -g angular-cli

应该替换为

npm install -g @angular/cli

错误中也提到了这一点。使用新命令重试。

Answer 2

问题是我的互联网连接不稳定。现在一切正常。

如果您遇到相同的错误并且您位于公司网络后面，那么您需要更改配置以添加代理，如下所示：

1. 在命令提示符中转到 node.js 安装位置并键入以下命令：

   npm config edit --g

2. 在文件末尾添加以下行： registry=http://registry.npmjs.org/ strict-ssl=false proxy=http://proxy.YOURCOMPANYNAME.com:8080

3. 然后执行 npm install 命令： npm install -g @angular/cli@latest
