我试图第一次设置react js，但是在设置了node，npm和react app之后，我运行“ npm start”命令，但出现错误。

我尝试按照上面链接中的步骤进行安装。但是我遇到了以下错误。

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: spawn cmd ENOENT

at onErrorNT (internal/child_process.js:415:16)
 at process._tickCallback (internal/process/next_tick.js:63:19)

Emitted 'error' event at:

您可以尝试使用此link上可用的create-react-app。这样更容易，以后您不必创建 build 脚本和其他内容时就可以避免很多麻烦。

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

我安装了node.js，但无法运行“ npm start”来处理React js
