我现在有个问题。如果我跑
au build
au build –env prod
或
我没有问题。
如果我跑
au build
au build –env prod
要创建应用程序包和供应商包-[identifier].js,我没有收到任何错误,但这两个文件最终都是空的,或者只是其中有“undefined”
Node.js版本:6.11.2(当前最新版本)
NPM版本:3.10.10
有人有主意吗?它是否与缩小机制有关(在dev中不会发生这种情况)
如何调试/记录发生的错误
更新:
我已经在aurelia.json文件中为开发环境激活了缩小功能,这就是我得到的

如果我为dev激活缩小,它也不起作用,给出了我上面粘贴的错误。如果我同时删除sourcemaps,它将不起作用(两个包都未定义),但不会出现错误消息。我认为您现在可以执行
au build
(无--env prod
标志。升级到最新版本的aurelia cli npm模块(0.31.3)所有其他模块的最新版本都解决了这个问题。thanx提示一下,但不是,这个问题只发生在prod中,我认为这是由缩小造成的,因为如果我也为dev打开它,它就不起作用了。对不起,我也应该把它作为一个注释而不是答案,因为这只是一个猜测。
