ng serve：找不到模块“@angular-devkit/build-angular”。

这个问题已经有答案了：

Angular 6 - 找不到模块 \"@angular-devkit/build-angular\"

我知道这个问题已经有答案，但是没有一个答案可以解决我的问题，我仍然得到了这个错误的堆栈:

Could not find module "@angular-devkit/build-angular" from "F:\\Documents\\...".

我的全局npm依赖项在C:，但我的项目文件夹和项目依赖项在F:

我尝试过:

• 使用npm在本地和全局安装模块
• 删除package-lock，本地node_modules，全局node_modules和npm-cache
• 卸载再安装node
• 使用ng new生成一个新应用程序，然后使用npm start/ng serve启动它产生了相同的错误
