ecmascript-6 - 如何在 create-react-app 中定义 process.env.ENV？

Question

同版本1.0.5的create-react-app样板我已经开始收到休耕警告:*** process.env.ENV is not defined, assuming 'prod' env
我知道如何创建自定义环境变量，但那些需要 REACT_APP_字首。

现在，我发现显示消息是因为 Chrome 的 Grammarly扩展，并禁用它会删除消息。

但是，无论扩展名如何，我都想知道如何解决此问题。

我知道 StackOverflow 上还有 2 个这样的问题，但它们包括使用 Webpack 的解决方案。不幸的是，我无法访问 Webpack，因为我还没有弹出 create-react-app，而且我不打算很快这样做。

有没有办法在 process.env.ENV 上声明环境在 create-react-app ?

编辑:

这是主要问题。技术上是否可以在 中定义它？未弹出 create-react-app ?

Answer 1

语法扩展不是 React 的原因。已向 Grammarly Support 记录了一个请求，这是结果

The console window in Chrome is constantly showing the warning - "process.env.ENV is not defined" turning off the extensions removes the error, it is not related a specific website. Already on the internet threads are popping up with people reporting the same issue and the common thread is Grammarly. Has a bug been introduced into the extension perhaps?
