angular-cli angular

我和Angular 4有个项目。

我更新了命令行:

Angular CLI: 6.1.5
Node: 10.9.0
OS: win32 x64

ng serve 我和Angular 4的项目?

文件 angular.json 角4不存在。

谢谢你。

AngularCLI紧跟角度释放。尤其是像这样的开关 angular.json 我怀疑有什么有效的方法来处理这个案子。如果升级项目是不可能的,我建议降级的CLI。

请注意,即使 https://update.angular.io/ 不建议跨多个主要版本移动项目:

但是,如果你选择升级一个主要版本,有两件事要做来处理这个问题。无论如何,这是一个困难的话题。如果您使用的是旧版应用程序,无法轻松升级该应用程序,我建议您选择降级。

我建议您在PC上安装最新版本的AngularCLI,并在计算机中指定其他版本 package.json . 每次启动时,您都会收到一条警告,告诉您“您的AngularCLI版本高于中的版本”包.json. 将使用本地版本而不是全局版本。“。这只是一个信息,什么也不做。

谢谢你的回答。

因此,在dev环境中,我可以使用以下命令运行 npm install 和 ng serve . 之后这个 Angular CLI: 6.1.1 更改为 @angular/cli: 1.1.1 .
