在生产模式下不能 运行

Question

我有一个 donejs 应用程序，它在开发模式下 运行 正常 donejs develop，但是当我在生产模式下 运行 它时：

1. donejs build
2. donejs deploy（到 Firebase）
3. NODE_ENV=production donejs start

它不会启动并显示错误（参见代码 A）

This file: file:my-app/dist/bundles/my-app/index.js:704 对应 JQuery 3.x 并且它不是项目本身的依赖而是 can-connect-feathers (https://github.com/canjs/can-connect-feathers) 的依赖.事实上，在 index.js 中还包含 JQuery 2.x 这让我觉得它们之间可能存在某种不兼容。

我已经尝试将项目的依赖项更改为 JQuery 3.x 但没有帮助。实际上它甚至会使 donejs develop 失败（参见代码 B）。

我还尝试了以下方法： cd my-app/node_modules/steal npm install 但没有帮助，出现另一个错误并最终尝试 cd my-app/node_modules/can && npm install 但最终出现多个错误。

我正在使用：

• donejs@0.9.2
• node@4.6.2
• npm@2.15.11
• can-connect-feathers@1.2.1

如果是双jQuery安装的问题，应该是2.0.0版本解决的，和1.0版本完全一样，只是需要传入一个jQuery打包为 jquery 选项。因此，除了 can-connect-feathers 配置中的任何其他内容之外，您还需要提供 jquery 选项：

import $ from 'jquery'
import Feathers from 'can-connect-feathers';

new Feathers({
  jquery: $
});
