【问题描述】：

我正在尝试创建一个新的 react 应用程序，但我似乎做不到。我到处搜索，尽我所能，无能为力。我已经删除了 node、npm 和 npx 两次并再次下载，然后重新启动计算机 100 次，但没有任何效果：

Need to install the following packages:
  create-react-app
Ok to proceed? (y) 

You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0).

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:

然后，如果我尝试 npm uninstall -g create-react-app 或其他任何东西，它总是会发送此错误：

我该如何解决这个问题？

【问题讨论】：

这个命令能解决你的问题吗？ sudo npm uninstall -g create-react-app
我也遇到了同样的情况。它看起来应用程序已更新，并迫使您更新。我按说卸载并使用“npx create-react-app my-app”再次安装。

标签： reactjs terminal create-react-app

【解决方案1】：

首先，移除包裹。如果你已经使用 npm 安装了 create-react 包，那么使用

- npm uninstall -g create-react-app

或者如果纱线

- yarn global remove create-react-app

然后就可以创建项目了：

npx create-react-app my-app

【解决方案2】：

问题似乎是安装不当。解决此问题的首选方法是确保正确卸载 node 和 npm。请按照提到的步骤here。正确卸载后，前往install node 并继续重新安装。
