今天，当我在创建react应用程序时，它得到了一个错误:
You are running create-react-app 4.0.3, which is behind the latest release (5.0.0). We no longer support the global installation of Create React App.
修复运行create-react-app 4.0.3，它落后于最新版本（5.0.0）
在我的系统中，我用下面的命令创建了一个反应式应用程序
A:\work>npx create-react-app kend-react-examples
Need to install the following packages:
create-react-app
Ok to proceed? (y) y
You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0).
We no longer support the 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/
React应用程序没有被创建，相反，它抛出了一个错误。
在我的系统中，有两个版本的本地create-react-app安装和npx create-react-app不匹配。
它建议删除全局安装
我尝试用下面的命令来卸载
npm uninstall -g create-react-app
再次，创建了一个应用程序，得到了同样的错误。
uninstall globally命令并没有单独解决我的问题。
那么，你是如何解决这些问题的？
有多种方法来解决这个问题。
第一种方法，清除npx全局缓存，获得最新的软件包并运行
npm uninstall -g create-react-app
npx clear-npx-cache
npx create-react-app kendo-react-app
上面的命令可以
- 全局卸载create-react-app CLI
- npx清除缓存
- 创建一个反应应用
通过上述步骤，它是有效的，如果它不工作，尝试下面提到的第二种方法。
另一种方法是用最新的软件包运行npx，使用强制选项。
npx create-react-app@latest kendo-react-appp --use-npm
现在，创建反应应用程序，它的工作原理如下所示
A:\work>npx create-react-app kend-react-examples
Need to install the following packages:
create-react-app
Ok to proceed? (y) y
