我遵循这些步骤，符合https://github.com/dart-lang/custom-element-apigen：
.bowerrc使用以下内容创建 {
"directory": "lib/src"
}
bower install --save paper-datatable（https://github.com/David-Mulder/paper-datatable）已执行
apigen.yaml使用以下内容创建
files_to_generate:
- paper-datatable\paper-datatable.html
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上无效。有关https://github.com/dart-lang/custom-element-apigen/issues/43的详细信息。
作为一种解决方法，我使用以下内容创建process_elements.bat（而不是process_elements.sh）：
node packages\custom_element_apigen\src\js\analyze.js %1
我修改了generate_dart_api.dart并将来电.bat改为.sh改为：
'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，我得到了一个工作场所！
第二次错误，我没有解决！
现在，执行命令c:\dart-sdk\bin\pub run custom_element_apigen:update apigen.yaml时会出现以下问题：
D:\Users\Administrador\WebstormProjects\Facilis>c:\dart-sdk\bin\pub run custom_e
lement_apigen:update apigen.yaml

我做错了吗？或者这是一个错误吗？
谢谢！
答案 0 :(得分：2)
这是一个错误，包装在Windows上未经测试，因为它主要是由聚合物飞镖队使用。
一般来说，修复程序只需要像现在一样加载.bat文件，然后调整路径以使用正确的目录分隔符。
