angular - 升级 Angular 和项目后找不到编译器 ngcc 模块

Question

我刚刚将 Angular cli 和我的一个项目从 7.0.7 升级到 7.1.0。

我关注了this post和 @Francesco Borzi's回答。

现在我尝试使用以下方式运行我的项目:

ng serve --proxy-config proxy.conf.json

收到这条消息

Cannot find module '@angular/compiler-cli/ngcc' Error: Cannot find

在您的 package.json 文件中，将 devDependencies 中的 @angular/cli 版本更改为:

"@angular/cli": "7.1.0"

您的项目和 devDependency 之间存在版本不匹配。您可能已经使用了 npm audit fix --force 或类似的自动更新命令，它们可能已经更新了“package.json”文件中的 devDependencies。

您还可以在此处的 devDependencies 中使用 angular cli 版本 7.3.5。只要确保开发版本和 devDependencies 中提到的版本兼容即可。请注意，本地 anglular/cli 版本在这里并不重要。

更新:进行更改后，删除“package-lock.json”并删除“node modules”文件夹。运行 npm install 再次安装模块。
