我真的不知道为什么，但是当我从 Angular 4 => 5 升级时，ng serve 似乎没有工作并且抛出错误:
ERROR in _this.host.getOutputName is not a function
webpack: Failed to compile.
这是我的包裹的样子:

最佳答案
这是已知问题 https://github.com/angular/angular/issues/21621
考虑安装相同版本的 Angular 依赖项:
"@angular/common": "^5.0.0",
"@angular/compiler": "^5.0.0",
然后在你的 devDependencies 中我看到了
"@angular/compiler-cli": "^4.0.0",
"@angular/language-service": "^4.0.0",
关于javascript - _this.host.getOutputName 中的 Angular 5 错误不是函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48559101/
