找不到本地"打字稿"包."@ ngtools/webpack"包Angular 2

Question

我在这里搜索了Angular 2,@ ngtools/webpack,AOT,但不适合我.我跑了npm install命令.我正在做的是我正在创建一个新的Angular 2项目.然后我跑了ng serve --open然后我得到了以下错误.

找不到本地的"typescript"包."@ ngtools/webpack"包需要安装本地"typescript@^2.0.2"包.错误:找不到模块'typescript'

任何帮助将受到高度赞赏.

下面是堆栈跟踪:

Answer 1

为了在评论部分没有答案,这里的错误是自解释的:

"@ ngtools/webpack"包需要安装本地"typescript@^2.0.2"包

所以webpack需要打字稿,你只需要安装它.

npm install typescript@latest --save-dev
