在Dart I中我尝试使用custom_element_apigen导入为Polymer编写的元素（特别是paper-typeahead-input和paper-typeahead）。
运行apigen脚本时出现此错误：
pub run custom_element_apigen：update configfile.yaml
[32m1 of 1: lib\src\paper-typeahead-input/paper_typeahead_input.html[0mUnhandled exception:
Uncaught Error: ProcessException: %1 non è un'applicazione di Win32 valida.
Command: packages/custom_element_apigen/src/js/process_elements.sh lib\src\paper-typeahead-input/paper_typeahead_input.html

有人可以告诉我什么是相关的吗？因为我不明白.....非常感谢！
