我按照步骤，符合 https://github.com/dart-lang/custom-element-apigen：
- 已安装节点/npm （v3.5.3）
- 鲍尔 （v1.7.2） 已安装
- 已安装水解 （v1.21.4）
- 使用以下内容创建的
.bowerrc
{
"directory": "lib/src"
}
-
bower install --save paper-datatable（https://github.com/David-Mulder/paper-datatable） 已执行 -
使用以下内容创建的
apigen.yaml
files_to_generate:
- paper-datatablepaper-datatable.html
- custom_element_apigen库插件在pubspec.yaml上
dependencies:
custom_element_apigen: ^0.2.1+1
-
pub run custom_element_apigen:update apigen.yaml命令已执行。
此命令中的错误
第一个错误：在 Windows 上不起作用。有关 https://github.com/dart-lang/custom-element-apigen/issues/43 的详细信息。
作为解决方法，我创建了包含以下内容的process_elements.bat（而不是process_elements.sh）：
node packagescustom_element_apigensrcjsanalyze.js %1
我编辑了generate_dart_api.dart并将呼叫.bat更改为.sh：
'D:/Users/Administrador/AppData/Roaming/Pub/Cache/hosted/pub.dartlang.org/custom_element_apigen-0.2.1+1/lib/src/js/process_elements.bat', [inputPath]);
然后，我得到了一个工作轮！
第二个错误，我没有解决！
现在，执行命令c:dart-sdkbinpub run custom_element_apigen:update apigen.yaml时出现以下问题：

lement_apigen:update apigen.yaml

我做错了什么吗？还是这是一个错误？
谢谢！
这是一个错误，该软件包未经在Windows上测试，因为它主要由聚合物飞镖团队使用。
看起来总的来说，修复程序只需要像您已经做的那样加载.bat文件，然后调整路径以使用正确的目录分隔符。
