Question

我正在尝试运行我的应用程序，但出现此错误。我尝试了一些在Internet上找到的解决方案，例如卸载angular / cli，重新安装，检查package.json中的版本是否正确，以及devDependencies中的@angular/cli是否比@angular-cli正确，并且其他一些东西，例如卸载和安装npm，删除节点模块并重新安装，但是以前的方法都没有解决我的问题... 这是我的package.json

Answer 1

没有什么可以尝试此错误的

您可以使用以下命令查看其是否有效。

npm uninstall angular-cli -g
npm uninstall angular-cli --save
npm install -g @angular/cli
npm install @angular/cli --save
npm install @angular/compiler-cli --save

Answer 2

我已经尝试了在其他Stackoverflow和github线程中找到的所有内容，但是对我有用的唯一方法是将angular @ cli降级到7.2（这是我项目中当前的angular软件包版本）并手动安装以下软件包：

npm install @ angular / compiler-cli --save

npm install @ angular-devkit / build-angular

我的package.json包含了这两个依赖关系，但是npm install似乎无法安装它们。所以我不得不手动做。

据我了解，这是新旧版本的angular / cli之间的问题。

希望我能帮上忙！

Answer 3

几个月前，我遇到了同样的问题。我尝试了以下步骤，并且能够编译代码而没有任何其他问题：

您可以创建一个空的角度项目并比较它们的package.json并手动编辑角度依赖性。
删除node_modules和package-lock.json
运行npm i --save

在我的应用上运行“ ng serve”时，“找不到模块'@ angular / compiler-cli / ngcc'”
