Question

我正在向heroku部署快速和反应项目，所有似乎都进展顺利，直到我运行postinstall来构建我的项目。我设置了heroku config:set NODE_ENV=production，但是当我运行git push heroku master时，它会安装所有依赖项，然后进入npm构建，因为它尝试访问仅用于开发环境的require文件。

当我设置dev环境=生产时，这很疯狂。下面是我的package.json脚本。

  "scripts": {
    "start": "node server/app.js",
    "dev": "nodemon server/app.js",
    "build": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.prod.config.js --progress --colors",
    "heroku-postbuild": "npm run build"
  },

这是我得到的错误。

错误：

   remote:        ERROR in ./server/config/config.js
    remote:        Module not found: Error: Can't resolve './config.json' in '/tmp/build_918738f52e06005c6e2c99818c8fcedf/server/config'

这是需要./config.json

的文件

config.js

var env = process.env.NODE_ENV || 'development';

console.log("env = ", env);

if(env === 'development' || env === 'test'){
  var config = require('./config.json');
  var envConfig = config[env];
  Object.keys(envConfig).forEach(function(key){
    process.env[key] = envConfig[key];
  })
}
module.exports = process.env;

因此，只有在process.env.NODE_ENV =开发时，config.js才需要config.json。

如果环境是生产环境，它如何才能访问它？

Heroku试图在生产中请求开发文件
