reactjs - create-react-app 自 4.0.1 版起不起作用

Question

我尝试安装 create-react-app使用 npm i create-react-app , npx create-react-app new-app和 npm init react-app new-app ，但我不断收到此错误消息:

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.

我怎样才能解决这个问题？

Answer 1

所有现有答案都不正确。
According to the create-react-app docs , create-react-app应该不是 全局安装:

If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app or yarn global remove create-react-app to ensure that npx always uses the latest version.

这甚至在您收到的错误消息中说明:

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.

(强调我的)

您必须卸载 create-react-app与 npm uninstall -g create-react-app .
然后每次你想用 create-react-app 创建一个新的 React 应用程序时，使用命令 npx create-react-app my-app .
因此，要修复您遇到的错误，请卸载 create-react-app全局更新 npm，清除缓存，然后重试创建应用程序。
在你的终端中运行这个:

npm uninstall -g create-react-app && npm i -g npm@latest && npm cache clean -f && npx create-react-app my-app
