我将其升级到Angular8.我使用下面的链接进行了更改:

将Angular 4升级到angular 8后出现的问题

我也阅读了Angular.io，但没有为我工作. 因此，我将其升级为Angular5.在控制台中没有出现问题，但是在运行应用程序Ui时未显示.

I have also read Angular.io but not working for me. So I upgared it to Angular 5. I did not get issue in console but when I run application Ui is not displaying.

升级之前是否需要先将system.js转换为CLI?

Do I need to convert system.js to CLI first before upgrading?

推荐答案

尝试一下:-

最好创建一个新项目并将模块移到新项目中.然后根据当前应用程序的复杂性，配置package.json, angular.json and tsconfig.json并使用npm命令npm install

Try this:-

It would be better if you create a new project and move modules into the new project. Then based on complexity of your current application configure your package.json, angular.json and tsconfig.json and install packages using npm command npm install

将项目从SystemJS移至Angular CLI/Webpack
