我正在尝试运行我的应用程序，但收到此错误。我尝试了一些我在互联网上找到的解决方案，例如卸载 angular/cli，重新安装它，检查我的 package.json 中的版本是否正确，如果它比 devDependencies 中的@angular-cli@angular/cli，以及其他一些东西，例如卸载和安装 npm，删除节点模块并重新安装它，但之前都没有解决我的问题...... 这是我的包.json

尝试此错误的几件事
您可以使用这些命令查看它是否有效。
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
我已经尝试了在其他 Stackoverflow 和 github 线程中找到的所有东西，但唯一对我有用的是将angular@cli降级到 7.2(这是我项目中当前的角度包版本)，并手动安装以下包：
npm install @angular/compiler-cli --save
npm install @angular-devkit/build-angular
我的package.json包含这两个依赖项，但是npm安装似乎无法安装它们。所以我不得不手动完成。
据我了解，这是角度/cli的较旧版本之间的问题。
希望我能帮到忙！
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不会出现任何问题：
- 您可以创建一个空的角度项目并比较它们
package.json并手动编辑角度依赖项。 - 删除
node_modules和package-lock.json - 运行
npm i --save
