聚合物2.0 webcomponents-loader.js缺少Edge Polyfill [英] Polymer 2.0 webcomponents-loader.js is missing Edge polyfill

问题描述

我们当前将项目从Polymer 1更新为Polymer 2/混合版本.

我知道webcomponents-hi-sd-ce.js是用于边缘的polyfill. 在Microsoft Edge上测试页面时，我现在收到一条错误消息，指示找不到webcomponents-hi-sd-ce.js.map(404). 使用webcomponents-lite.js加载项目时发生相同的错误

我找不到类似的案例，所以我发现这可能是Polymer 2中的问题.我尝试直接由我自己导入脚本，但这也无济于事.

如果有人可以在这里帮助我或分享他的类似问题的经验，我将不胜感激.

Edge v.38的确切错误: HTTP500 +由于某种原因，即使实际上在我的文件夹中，文件路径也显示不正确. https://..../bower_components/webcomponentsjs%20 [synthetic :util/global]

We currently updated a project from Polymer 1 to the Polymer 2/ hybrid version.

I know that webcomponents-hi-sd-ce.js is the polyfill for edge. When testing the page on Microsoft Edge I now get an error indicating that webcomponents-hi-sd-ce.js.map could not be found (404). The same error occurs when loading the project with webcomponents-lite.js

I couldn't find similar cases so I figured this might be a issue in Polymer 2. I tried importing the script directly by myself but that didn't help either.

I would appreciate if someone could help me out here or share his experience with a similar problem.

The exact error from Edge v.38: HTTP500 + for some reason the file path is shown incorrect even though it is actually right in my folder. https://..../bower_components/webcomponentsjs%20[synthetic:util/global]

推荐答案

在调试加载程序时，我发现了以下问题:

Debugging the loader, I've found the following issue:

对于每个不存在的本机平台功能(由加载程序确定)，首字母缩写将附加到polyfill URL. 不幸的是，对于某些功能组合(例如与MS Edge一样)，结果路径不可用.

For each absent native platform feature (as determined by the loader) an acronym will be appended to the polyfill URL. Unfortunately, for some combinations of features—-as with MS Edge—-the resulting path is unavailable.

这可能已经解决了，但是我继续使用webcomponents-lite(因为我们 仅支持Edge).

This might have been resolved meanwhile, but I've moved on to just using webcomponents-lite (since we're only supporting Edge).
