angular - 找不到本地 "typescript"包。 "@ngtools/webpack"包 Angular 2

Question

我在这里搜索过，Angular 2, @ngtools/webpack, AOT ，但对我不起作用。我运行了 npm install 命令。我正在做的是创建一个新的 Angular 2 项目。当我运行 ng serve --open 然后我得到了以下错误。

could not find local "typescript" package.The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed.Error: Cannot find module 'typescript'

我们将不胜感激。

下面是堆栈跟踪:

C:\Users\jang\Desktop\kendoGrid>ng version`

Answer 1

为了在评论部分没有答案，这里的错误是不言自明的:

The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed

所以 webpack 需要 typescript，你只需要安装它。

npm install typescript@latest --save-dev
