custom_element_apigen: выдает ошибку при импорте данных из бумаги в Dart

Следуя шагам, согласен с https://github.com/dart-lang/custom-element-apigen:

  1. узел /npm (v3.5.3) установлен
  2. Бауэр (v1.7.2) установлен
  3. гидролиз (v1.21.4) установлен
  4. .bowerrc создано со следующим содержанием

{ "directory": "lib/src" }

  1. bower install --save paper-datatable ( https://github.com/David-Mulder/paper-datatable) выполнено

  2. apigen.yaml создано со следующим содержанием

files_to_generate: - paper-datatable\paper-datatable.html

  1. библиотека custom_element_apigen добавить на pubspec.y aml

dependencies: custom_element_apigen: ^0.2.1+1

  1. pub run custom_element_apigen:update apigen.yaml Команда выполнена.

ОШИБКА В ЭТОЙ КОМАНДЕ

Первая ошибка: на Windows не работает. Подробности на https://github.com/dart-lang/custom-element-apigen/issues/43.

В качестве обходного пути я создаю process_elements.bat (вместо process_elements.sh) со следующим содержанием:

node packages\custom_element_apigen\src\js\analyze.js %1

Я редактирую generate_dart_api.dart и изменил вызов .bat вместо .sh чтобы:

'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]);

Затем я получил обходной путь!

Вторую ошибку я не разрешил!

Теперь возникает следующая проблема, когда команда c:\dart-sdk\bin\pub run custom_element_apigen:update apigen.yaml выполняется:

D:\Users\Administrador\WebstormProjects\Facilis>c:\dart-sdk\bin\pub run custom_e
lement_apigen:update apigen.yaml

Я делаю что-то неправильно? или это ошибка?

Спасибо!

Решение

Это ошибка, пакет не тестировался в Windows, поскольку он в основном использовался командой полимерных дротиков.

В целом это выглядит так, как будто исправление просто требует загрузки .bat файл, как вы уже сделали, а затем настройте пути, чтобы использовать правильный разделитель каталогов.

См. https://github.com/dart-lang/custom-element-apigen/issues/43.
