【问题描述】：
之前类似帖子给出的解决方案对我不起作用。
我是 Angular 开发的新手，正在尝试从头开始学习。我在尝试创建我的第一个应用时遇到了问题。
环境
-
Windows 10
-
使用 GitBash 安装 Angular 最新版本
-
节点版本：v12.14.0
-
NPM 版本：6.13.4
-
Angular CLI 版本：8.3.21
问题
- 给出安装新项目的命令。
新测试
-
一段时间后它会产生以下错误。
npm WARN deprecated core-js@2.6.11: core-js@
-
我试图退出。但是经过不同的帖子后，我才知道，安装将毫无问题地进行。我跟着它。终于安装成功了。
-
但在成功安装消息之前，它会在 core-js 安装后生成大量消息、npm WARN、0 漏洞、警告等。
这是最后的信息。

我想知道为什么会出现这样的 core-js 和其他问题。我的系统和环境是否有任何故障。或者，NodeJS 上存在一些安装问题。或者，这是一个简单而被忽视的问题，任何人都可能发生。
【问题讨论】：
-
请检查您的 package.json。我认为有些软件包没有安装。
-
这里没有什么要解决的。这些都是警告。继续前进。
