有一个新项目，但是当ng服务时出现错误

Question

我需要更改此主题，我无法发布新主题。 我已经更新了脚本，并安装了新软件包。 我仍然遇到错误，但最后一次发帖失败。

我找不到此错误的答案。 我希望我现在可以找到答案，这样我就可以继续使用该脚本。

Answer 1

我建议阅读：

https://www.techiediaries.com/updating-angular-cli-projects/

在此页面上指出：

Angular 6使用angular.json而不是angular-cli.json。 可以使用：

ng update @angular/cli

这解决了我的问题。

祝你好运

Answer 2

Angular 6会寻找angular.json而不是angular-cli.json。

您需要更新@angular/cli。添加到以上答案

我确实使用以下命令更新了所有软件包，并且也更新了所有依赖项。从而消除与其他软件包的所有兼容性问题。

如果要启动您的应用程序或演示应用程序，请遵循以下步骤。如果您要针对生产应用执行此操作，请格外小心。

npm install -g npm-check-updates
ncu -u
ng update @angular/cli
npm install

安装npm-check-updates

npm install -g npm-check-updates 

使用ncu更新您的package.json

ncu用于显示

ncu -u用于重写package.json

更新您的@ angular / cli以将您的应用程序修改为与angular 6兼容

ng update @angular/cli 

并运行npm install来更新您的软件包

Answer 3

重新安装@ angular / cli

npm install @angular/cli

Answer 4

只需使用官方的升级指南，它会告诉您您需要满足自己的特殊需求：

https://update.angular.io/

Answer 5

就我而言，我只需要在删除/重新克隆仓库后关闭/重新打开终端。不知道那里发生了什么。

Answer 6

这似乎是由于安装了不同版本的angular-cli引起的。 我只是使用新命令创建了一个新项目，然后将其复制到src目录中。然后全部编译成功。

    ng new UX7
