为避免发布另一个重复项，我已经尝试了以下操作，但没有成功。我已经开始了好几次，但仍然得出相同的结果：
rm -r node_modules (or delete your node_modules folder manually)
npm cache clean (npm > v5 add --force so: npm cache clean --force)
npm install
也无法工作：
npm uninstall angular-cli
npm install @angular/cli --save-dev
我可能看不到这很愚蠢，但似乎无论我做什么，然后尝试构建，我最终都会得到相同的结果。我什至没有能够改变错误。
然后我做了npm i @angular/compiler，它产生了一个新错误：You seem to not be depending on "@angular/core" and/or "rxjs". This is an error.
然后我尝试了npm cache clean --force和npm install和npm link都对错误没有影响。
答案 0 :(得分：1)
尝试单独安装编译器：
npm i @angular/compiler
通过上述或@angular/cli检查node_modules是否成功安装。
如果问题仍然存在：
npm uninstall angular-cli
npm cache clean --force
npm install @angular/cli --save-dev
对于错误：
您似乎不依赖于“ @ angular / core”和/或“ rxjs”。
npm link
