reactjs - npm 卸载 - g create-react-app checkPermissions 错误

Question

我是reactjs的新手，我正在尝试创建一个reactjs应用程序，我按照react web上的步骤操作，它显示错误。我的节点版本是 v12.19.0，我的 npx 版本是 6.14.8

当我尝试时，我npx create-react-app ac-web在终端中收到此消息

hazeleroy@Hazels-MacBook-Pro acweb % npx create-react-app ac-web

You are running `create-react-app` 4.0.0, which is behind the latest release (4.0.1).

We no longer support global installation of Create React App.

Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app

The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/

我去网站，它告诉我使用npm uninstall -g create-react-app

我收到这条消息
