无法确定项目使用的本机SDK版本，因为未安装模块“expo”。Ubuntu 20.04

我最初使用Thread安装expo cli，但它不起作用，所以我只是使用npm进行全局安装。使用

expo init“site name”--name“name”-t blank--warn创建新项目后，expo start不再工作。完成后，我下载了Android Studio并启动了一个虚拟设备

这是我键入
expo start
后的错误消息：

更新
npm
至最新版本->
npm安装-gnpm@latest

卸载expo->
npm卸载-g expo cli--保存

删除了.expo文件夹，重新安装的expo可以工作
我的目录完全错了。简单的错误，简单的修复。
谢谢你，但这并不能解决我的问题
