main.js里的app config无法使用process.env.NODE_ENV?

maimake commented 6 years ago

我想根据NODE_ENV配置app.json：

const app = new Vue(App)
app.$mount()

export default {
  // 这个字段走 app.json
  config: {
    pages: [],
    window: {
      backgroundTextStyle: 'light',
    },
    debug: process.env.NODE_ENV !== 'production',
  },
}

然后热更新报错

 ERROR  Failed to compile with 1 errors                                                                                     11:30:43

如果重新编译的话，终端停住，一直等都没有出结果

这个目前是 mpvue-loader 的问题，解析这块的时候没有注入这个变量

这部分是纯 json，即使注入了变量，在开发模式下不启用压缩生成的代码依然是不正确的，建议在其他地方进行此类配置，例如 vue 原型什么的

F-loat / mpvue-entry
