用于生产的Aurelia构建会创建具有“未定义”内容的捆绑包

标签： aurelia aurelia-cli

您好我有一个通过Aurelia CLI构建的Web应用程序。为了解决性能问题（我解决了here），我更新了最新版本的Aurelia（0.30.1，修复了性能问题）。为此，我必须更新其他npm软件包，首先使用npm-check-updates软件包将semver强制为最新版本

npm install -g npm-check-updates
ncu --upgrade
npm update
npm install babel-runtime --save-dev
npm install timers-ext --save-dev
npm install gulp-sourcemaps --save-dev
npm install aurelia-pal --save-dev
npm install aurelia-binding --save-dev
npm install aurelia-templating --save-dev

这是我的aurelia.json文件

          }
        ]
      }
    ]
  }
}

我现在有一个问题。如果我跑

au build

或

au run –watch

我没问题。 如果我跑

au build –env prod

创建app-和vendor-bundle - [标识符]。js，我没有得到任何错误，但是这两个文件最终都是空的，或者更确切地说是“undefined”它们。

Node.js版本：6.11.2（当前最新稳定版）

NPM版本：3.10.10

有没有人有想法？它是否与缩小机制有关（在开发中不会发生）

如何调试/记录出错的地方？

更新：

我已经为aurelia.json文件中的开发环境激活了缩小，这就是我得到的

如果我为dev激活缩小，它也不起作用，给出上面粘贴的错误。如果我也删除了源图，它不起作用（两个包都未定义）但没有错误消息。

升级到最新版本的aurelia-cli npm模块（0.31.3），所有其他模块升级到最新版本，解决了这个问题。

答案 1 :(得分：-1)

我认为你现在可以做au build（没有--env prod标志。
