google-app-engine - DartEditor Pub Build谷歌应用引擎

Question

我已经在Dart中编写了一个webapp。在服务器端，我使用DartForce MVC框架，在客户端端，我使用AngularDart。如果我在DartEditor中构建，则会收到此错误

* WARNING: dart:mirrors support in dart2js is experimental,

如果我用

pub build

放入我的项目文件夹中，这将生成不完整的版本:仅生成Web文件夹。

这是我的pubspec.yaml

name: dartrest
dependencies:
  angular: 1.0.0
  appengine: '>=0.2.4 <0.3.0'
  browser: any
  forcemvc:
    git: 'https://github.com/ForceUniverse/dart-forcemvc'
  http_server: '>=0.9.3 <0.10.0'
  logging: '>=0.9.0 <0.10.0'
  web_components: '>=0.9.0 <1.0.0'
dev_dependencies:
  mock: '>=0.11.0+2 <0.12.0'
  unittest: '>=0.11.0+5 <0.12.0'
transformers:
- angular:
    dart_sdk: /usr/lib/dart
    html_files:
    - lib/component/custom.html

有任何想法吗？

Answer 1

DartEditor似乎无法将特定的文件夹传递给pub build命令。您能在http://dartbug.com/new上创建一个错误报告吗？
如果只创建build/web文件夹，那就很好。
服务器代码可以按原样部署。有一个试验性的dart2dart选项(请参阅Run Dart WebApp on Apache Server)，但是对于当前设置Managed VMs的开发方式而言，部署bin目录而不进行构建就很好了(gcloud preview app run app.yaml默认)。
更新资料
因为转换器对于服务器端代码也很重要，所以运行pub build web bin是有意义的，但是对于Din2JS转换器而言，bin没有意义。
解决方法是添加此变压器配置

transformers:
- $dart2js:
    $exclude: bin/**.dart

到您的 pubspec.yaml文件。
据我所知，如果您还有其他人(例如 $dart2js， angular， di，...)， smoke转换器应该是列表中的最后一个
