由于“npm ERR！path Angular\appTwo\node_modules\acorn\bin\acorn”，Angular 项目创建失败

Question

以下是我用来创建我的第一个 Angular 应用程序的步骤。

• 安装NodeJS
• 安装 VSCode
• 检查了我的 NodeJS 和 npm 版本

• 执行了npm install -g @angular/cli，我在 VSCode 的集成终端中收到了以下日志（我相信这很好）

> PS C:\Users\Babar Baig\Desktop\Angular> npm install -g @angular/cli
C:\Users\Babar Baig\AppData\Roaming\npm\ng ->

+ @angular/cli@6.1.3

PS C:\Users\Babar Baig\Desktop\Angular>

• 执行ng new appTwo 来创建我的应用程序。以下是我收到的日志和错误。

这是我在谷歌上搜索 Angular 的项目创建问题后所做的事情

1. 卸载 NodeJS 和 Angular 并重新安装，但出现了同样的问题。
2. 重启了我的 VSCode，但还是不行。
3. 由于收到错误，通过npm install -g acorn 安装了 acorn。但同样的错误又发生了。

4. 在我的本地文件夹“Angular”中使用npm install @angular/cli 安装了Angular cli，然后执行新项目命令ng new appTwo。没有收到任何进展。

我了解“npm”无法从路径“C:\Users\Babar Baig\AppData\Roaming\npm\node_modules\acorn\bin\acorn”中找到“acorn”。 “node_modules”内没有“橡子”文件夹。但我不知道如何解决这个问题。

我从“\AppData\Roaming\npm-cache_logs”中找到它。任何帮助都将不胜感激，因为这是我第一次使用 Angular。

谢谢！

我使用以下链接来解决问题 docs.npm。 我执行了npm cache clean --force 来清理我的 npm 缓存。我在清理 npm 缓存后创建了一个新的 Angular 项目，它工作得非常好。

编码愉快！
