dart - 升级到聚合物后无法运行应用程序:^ 1.0.0-rc.10且可反射(reflect):^ 0.5.0

Question

我刚刚升级到聚合物:^ 1.0.0-rc.10，具有可反射的^ 0.5.0的dependecy_overrides。
我观察到，每当我使用上述聚合物和可反射的 Material 升级项目时，都会在输出中得到以下内容

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

运行发布缓存修复，但错误仍然存​​在。
请就如何最好地解决此问题提出任何建议。

我缩小了由web_component，可反射或聚合物引起的问题。
我用舞台助手创建了一个新的聚合物应用程序，该应用程序可以运行。
新的聚合物应用pubspec.yaml显示如下:

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

只要将依赖关系分别从0.40和1.0.0.rc9(带注释的行)更改为可反射的:0.5.0和聚合物:^ 1.0.0-rc.10(一致的行)，问题就会始终如一地再现。
我建议这里可能有一个错误。
我还注意到舞台手现在使用

transformers:
- reflectable:
    entry_points: web/index.bootstrap.initialize.dart

代替

transformers:
- reflectable:
    entry_points: web/index.dart

这些代码在工作上是否相似？
干杯

更新

当前解决方法
-删除.pub目录
-运行pub upgrade(错误消息仍显示)
-将分析仪限制为0.27.1版本(无0.26.x或0.27.1+1版本)

我不确定这是否也是发布问题，因为它与dev_dependency有关。
我在初始化包中创建了https://github.com/dart-lang/initialize/issues/43问题来修复pubspec.yaml。
