Heroku试图在生产中请求开发文件

我正在部署一个快速和反应的项目到heroku，似乎一切顺利，直到我运行postinstall来build立我的项目。 我已经设置了heroku config:set NODE_ENV=production但是当我运行git push heroku master它会安装我所有的依赖关系，然后进入npm构build失败的地方，因为它试图访问仅用于开发env的require文件。

这是疯狂的看到我设置开发环境=生产。 以下是我的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' 

这里是需要./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; 

所以config.js只有在process.env.NODE_ENV = development时才需要config.json。

如果环境是生产的话，它怎么能访问这个呢？
