推荐答案

全局安装 create-react-app 。而是通过执行以下操作来卸载全局安装的create-react-app软件包： npm uninstall -g create-react-app （如果此命令未执行，则可能必须手动删除软件包文件夹。

Installing create-react-app globally is now discouraged. Instead uninstall globally installed create-react-app package by doing: npm uninstall -g create-react-app (you may have to manually delete package folder if this command didn't work for you. Some users have reported they had to delete folders manually)

然后您可以运行 npx create-react-app my-app 再次创建react应用。

Then you can run npx create-react-app my-app to create react app again.
