Question

当我尝试使用

创建新的角度应用程序时出现此错误

ng new frontend

这是我得到的错误

npm ERR! Unexpected end of JSON input while parsing near '...dSize":36422127},"eng'

所以我提到了npm git问题，但是找不到解决方案，他们建议这可能是网络问题，并且有人建议重新安装或更新nodejs，npm和angular cli。我确实通过重新安装所有必需的软件来更新所有内容，但是当我尝试运行以下命令时-

npm install --save-dev @angular/cli@latest

我仍然遇到相同的错误。请建议我需要做些什么来创建一个角度为2+（4，5，6）的新ng应用程序。

更新根据日志，这是失败的地方-我也在较低版本的节点上尝试过

更新2 由于我发现安装Typescript时存在错误，因此我尝试使用

直接安装Typescript

 npm i -g typescript

我发现它正在尝试访问文件

https://registry.npmjs.org/typescript

并且我发现在json中只有一个这样的位置发生错误。这是新的日志：-

但是现在我该怎么办？请帮助我进行下一步。

我找不到问题的答案，因此尝试在Windows 10中使用新的用户帐户。现在，这对我有所帮助。对于Windows中的此类问题，我仍然感到非常不舒服。
