nextjs - 下一次构建 NODE_ENV=development

Question

我想将我的 nextjs 项目构建为开发模式。

我试过喜欢

package.json

{
  ...
  "scripts": {
    "dev": "next",
    "build:dev": "set NODE_ENV=development & next build",
    "build:prod": "set NODE_ENV=production & next build",
    "start:dev": "set NODE_ENV=development & next start",
    "start:prod": "set NODE_ENV=production & next start"
  }
  ...
}

next.config.js

module.exports = withSass({
  env: {
    baseUrl: process.env.NODE_ENV === "development" ? "devServerURL": "prodServerURL"
  }
});

但是我没有达到我想要的。

所以，我尝试了一些改变。

package.json

  "scripts": {
    "dev": "next",
    "build": "next build",
    "start:dev": "set NODE_ENV=development & next start",
    "start:prod": "set NODE_ENV=production & next start"
  }

但它也不起作用。

如何使用开发模式构建 next？

提前致谢。

参见issue #9123, (Oct 18, 2019)：

NODE_ENV is a reserved environment variable that cannot be changed. The only valid values are production, development, and test.

If you need your app behavior to change in different production environments, please use a different variable like APP_ENV.

和issues #17032 (Sep 12, 2020)：

process.env.NODE_ENV only has 2 possible values development and production. If this is not set to that value you'll run into all kinds of library edge cases (especially in node_modules) where you get severely de-optimized results. E.g. if you run a performance test you'll get significantly worse results if process.env.NODE_ENV is not set to production
