Dependency injection 来自InjectorGenerator的错误

所以，我显然升级了我的pub依赖项，现在我不能再启动我的webApp了，出现了很多错误。我试图降低依赖项的级别，但没有帮助

我的名字叫yaml

  browser: any
  bwu_polymer_routing: any
  core_elements: '>=0.1.1+2 <0.5.0'
  di: '>=3.3.2 <5.0.0'

  intl: any
  js: any
  polymer: any
  unittest: 0.11.3
transformers:

    entry_points:
