我刚刚升级到聚合物：^ 1.0.0-rc.10，带有可反射的dependecy_overrides ^ 0.5.0。
我观察到每当我使用上述聚合物升级项目并且可反射时，我在输出中得到以下行
Error on line 1, column 1 of https://pub.dartlang.org/api/packages/initialize: Invalid description: "test_package" is a relative path, but this isn't a local pubspec.
尝试运行我的应用程序失败，并显示以下错误

运行pub cache fix，但错误仍然存在。
有关如何最好地解决问题的任何建议。
我已经缩小了由web_component，reflectable或polymer引起的问题。
我用舞台手创建了一个新的聚合物应用程序，应用程序运行。
新的polymer-app pubspec.yaml如下所示：
name: 'ui_tester'
version: 0.0.1
description: A web app built using polymer.dart.
#author: Your Name <email@example.com>
#homepage: https://www.example.com
environment:
sdk: '>=1.9.0 <2.0.0'
dependencies:
browser: ^0.10.0
polymer_elements: ^1.0.0-rc.1
polymer: ^1.0.0-rc.10
reflectable: ^0.5.0
# polymer: ^1.0.0-rc.9
# reflectable: ^0.4.0
web_components: ^0.12.1
transformers:
- web_components:
entry_points: web/index.html
- reflectable:
entry_points: web/index.bootstrap.initialize.dart
- $dart2js:
$include: '**/*.bootstrap.initialize.dart'
minify: true
commandLineOptions:
- --trust-type-annotations
- --trust-primitives
一旦我将依赖关系改为可反映：0.5.0和聚合物：^ 1.0.0-rc.10分别从0.40和1.0.0.rc9（评论行），问题一致地再现。
我也注意到舞台手现在使用
transformers:
- reflectable:
entry_points: web/index.bootstrap.initialize.dart
而不是
transformers:
- reflectable:
entry_points: web/index.dart
代码与他们的相似吗？
干杯
