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（到火力基地）
  3. NODE_ENV=production donejs start

它不会启动并显示错误（参见代码 A）

此文件：file:my-app/dist/bundles/my-app/index.js:704对应于 JQuery 3.x，它不是项目本身的依赖项，而是 can-connect-feathers 的依赖项（https://github.com/canjs/can-connect-feathers）。事实上，index.js其中还包含 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donejs develop会失败（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。

我在用着：

  • donejs@0.9.2
  • 节点@4.6.2
  • npm@2.15.11
  • 可以连接羽毛@1.2.1

如果是双jQuery安装问题，应该通过2.0.0版本解决，和1.0版本完全一样，但是需要传入一个jQuery包作为jquery选项。因此，除了您在 can-connect-feathers 配置中的其他内容之外，您还需要提供以下jquery选项：

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

new Feathers({
  jquery: $
});
