Question

基本上是这个。我都试过了

npm init react-app my-app

和

npx create-react-app my-app

我总是收到这条消息：

我也更新了节点，但没有任何效果。我的 package.json 是空的，因为这是我尝试安装的第一个包，所以我也没有 node_modules 文件夹。我能做什么？

Answer 1

这是npm版本的问题。升级到最新版本的 npm：

npm install -g npm@latest

同时添加 babel：

npm install --save-dev @babel/core

如果这个解决方案不起作用，你可以简单地尝试旧的 npm 版本：

npm install npm@6.14.11 -g

由于与 babel 的依赖关系，安装 react 出现问题
