Google app engine DartEditor发布构建谷歌应用程序引擎

我在Dart中编写了一个网络应用程序。在服务器端，我使用DartForce MVC框架，在客户端，我使用AngularDart。如果我在DartEditor中编译，我会收到此错误

****************************************************************
* WARNING: dart:mirrors support in dart2js is experimental,
*          and not recommended.
*          This implementation of mirrors is incomplete,
*          and often greatly increases the size of the generated
*          JavaScript code.
*
* Your app imports dart:mirrors via:
*   server.dart => package:forcemvc => dart:mirrors
*   server.dart => package:forcemvc => package:mustache4dart => dart:mirrors
*   server.dart => package:forcemvc => package:forcemirrors => dart:mirrors
*   server.dart => package:forcemvc => package:wired => dart:mirrors
*   server.dart => package:forcemvc => package:wired => package:forcemirrors => dart:mirrors
*   server.dart => package:mustache4dart => dart:mirrors
*   server.dart => package:appengine => package:gcloud => package:http => dart:mirrors
*   server.dart => package:appengine => package:gcloud => package:googleapis => package:http => dart:mirrors
*   server.dart => package:appengine => package:gcloud => dart:mirrors
*   server.dart => package:appengine => package:http => dart:mirrors
*   server.dart => package:appengine => package:googleapis_auth => package:http => dart:mirrors
*
* Starting with Dart 1.9, you must use the
* --enable-experimental-mirrors command-line flag to opt-in.
* You can begin using this flag now if mirrors support is critical.

这将生成一个不完整的生成：只生成web文件夹

这是我的出版物

名称：dartrest
依赖项：
角度：1.0.0
appengine:'>=0.2.4=0.9.3=0.9.0=0.9.0=0.11.0+2=0.11.0+5似乎是DartEditor将特定文件夹传递给
pub build
命令的问题。你能在创建一个bug报告吗

如果只创建了
build/web
文件夹就可以了。

服务器代码可以按原样部署。有一个实验性的
dart2dart
选项（请参阅），但是对于当前设置的
托管虚拟机的开发方式，在不构建的情况下部署
bin
目录是很好的（默认为
gcloud preview app run app.yaml
）

使现代化
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，但是只有Dart2JS转换器对于bin没有意义

解决方法是添加此转换器配置

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

到您的
pubspec.yaml
文件

据我所知，
$dart2js
变压器应该是列表中的最后一个，如果您还有其他变压器（如
angular
，
di
，
smoke
，…）
请将您的
pubspec.yaml
添加到您的问题中。好的。我已经编辑了我的问题我更新了我的答案。在DartEditor中有一个推荐的
Run>Pub Build（generate JS）
，如果我运行这个，我就遇到了上面的问题。在shell中，我在我的项目文件夹中使用了这个命令
pub build
，所有工作正常，但新的构建文件夹似乎不完整。我在客户端使用AngularDart。这是一个例子：如果我在这个项目上运行Pub Build into Dart Editor，就会创建一个包含所有元素的新构建文件夹。问题在于DartEditor调用
Pub Build
，使用类似
Pub Build web bin
的东西，而不仅仅是
Pub Build
transformers:
- $dart2js:
    $exclude: bin/**.dart
