当我在我的终端上输入create-react-app my-app命令时，它似乎工作了-下载所有库成功等。在该过程结束时，我得到一个消息，没有提供模板。

输入

user@users-MacBook-Pro-2 Desktop% create-react-app my-app

输出

Creating a new React app in /Users/user/Desktop/my-app.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts...
..... nothing out of the ordinary here .....
✨  Done in 27.28s.

A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.

在包中。my-app的Json:

"dependencies": {
  "react": "^16.12.0",
  "react-dom": "^16.12.0",
  "react-scripts": "3.3.0" <-- up-to-date
}

我检查了CRA更改日志，它看起来像是增加了对自定义模板的支持-但是它看起来不像命令create-react-app my-app会改变。

知道这是怎么回事吗?
