您可以尝试使用 npm update 更新 npm看看是否能解决它，如果不能，你可以尝试这些步骤。
如果您以前安装过 create-react-app全局通过 npm install -g create-react-app ，建议您使用 npm uninstall -g create-react-app 卸载软件包或 yarn global remove create-react-app确保npx始终使用最新版本。
您还需要删除 chat-app 的剩余文件和文件夹。
一旦您在 /home/mikhil/react-tutorial/internshala-react-course目录并且您已经删除了全局安装，您可以尝试运行这些命令。

npx create-react-app my-app
cd my-app
npm start
