Angular-cli不会更新

Question

我需要将我的angular-cli更新到最新版本。当我运行时：

npm cache clean

我面临以下错误：

npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "cache" "clean"

另外，当我继续执行安装命令时：

npm install -g angular-cli@latest

我面对这样的错误：

那么，这个错误是什么，以及我如何修复它？

Answer 1

https://github.com/angular/angular-cli#updating-angular-cli

要将angular-cli更新到新版本，您必须同时更新全局包和项目的本地包，请单击链接

代码片段：

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

注意:始终以管理员身份运行命令提示符，有时您必须多次运行npm cache clean，直到错误消失

Answer 2

您应该以允许清除缓存的管理员身份运行cmd。一旦npm cache clean完成，你就可以成功安装angular cli了。
