For the sake of not having answers in the comments section, here the error is self explanatory: 为了在评论部分没有答案,这里的错误是自解释的:
The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed
“@ ngtools / webpack”包需要安装本地“typescript@^2.0.2”包
So webpack needs typescript and you just have to install it. 所以webpack需要打字稿,你只需要安装它。
npm install typescript@latest --save-dev
Yea this error also comes up when you upgrade "@angular/cli". 是的,当您升级“@ angular / cli”时,也会出现此错误。 Except that you can't fix it by merely installing typescript again.
除了你不能通过再次安装打字稿来解决它。
This is how I fixed it: 这就是我修复它的方法:
npm uninstall -g @angular/cli
npm uninstall --save-dev @angular/cli
npm install -g @angular/cli@latest
npm install --save-dev @angular/cli@latest
