node.js - React Native 项目由于错误而无法启动：EISDIR

Question

初学者在这里反应本地用户。

我尝试按照Mosh关于 React Native 的指南进行操作，但是当我运行 npm start 命令时，我在终端中收到此错误：

Opening DevTools in the browser... (press shift-d to disable)
error EISDIR: illegal operation on a directory, read.

npm 版本：6.14.6 节点版本：12.18.3 博览会版本：3.26.2

我运行的命令：

npm i -g expo-cli

博览会初始化 MyApp

*选定的空白托管工作流

cd MyApp

npm 开始

任何帮助将不胜感激。
