尝试创建新的角度应用程序时出现奇怪的错误

Question

当我尝试使用

创建新的 Angular 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 问题但我找不到解决方案，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

我仍然遇到同样的错误。请建议我需要做什么来创建一个具有 angular 2+( 4, 5, 6) 的新 ng 应用程序。

更新 根据日志，这是失败的地方-我也尝试过使用较低版本的节点

更新 2 由于我发现安装 Typescript 存在错误，我尝试使用

直接安装 Typescript

 npm i -g typescript

我发现它正在尝试访问一个文件

https://registry.npmjs.org/typescript

而且我还发现 json 中只有一个这样的位置会发生错误。这是新的日志：-

但是现在我该怎么办？请帮助我完成后续步骤。

我找不到问题的答案，因此我尝试在 Windows 10 中使用新用户帐户。它成功了。目前，这对我有所帮助。我仍然对 Windows 中的此类问题感到非常不舒服。
