Details on https://github.com/dart-lang/custom-element-apigen/issues/43.作为解决方法，我创建 process_elements.bat code> process_elements.sh ）具有以下内容：As a workaround I create process_elements.bat (instead process_elements.sh) with following content: 节点packages\custom_element_apigen\src\\ \\ js \analyze.js％1 我编辑 generate_dart_api.dart 已将通话 .bat 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，我得到了一个工作环境！Then, I got a workarround! 第二个错误，我没有解决！现在，当命令 c：\ dart-sdk \bin \pub run custom_element_apigen：update apigen.yaml 被执行：D:\Users\Administrador\WebstormProjects\Facilis>c:\dart-sdk\bin\pub run custom_element_apigen:update apigen.yaml←[32m1 of 1: lib\src\paper-datatable\paper-datatable.html←[0mUnhandled exception:Failed to parse element files!exit code: 0stderr:stdout:D:\Users\Administrador\WebstormProjects\Facilis>node packages\custom_element_apigen\src\js\analyze.js lib\src\paper-datatable\paper-datatable.html{"imports":["lib/src/polymer/polymer.html","lib/src/paper-datatable/paper-datatable-column.html","lib/src/paper-datatable/paper-datatable-edit-dialog.html","lib/src/paper-datatable/datatable-icons.html","lib/src/paper-checkbox/paper-checkbox.html","lib/src/paper-tooltip/paper-tooltip.html"],"elements":{"PaperDatatable":{"name":"paper-datatable","properties":{"data":{"hasGetter":true,"hasSetter":true,"name":"data","type":"Array","description":"\nArray of objects containing the data to be shown in the table.\n\n"},"multiSelection":{"hasGetter":true,"hasSetter":true,"name":"multiSelection","type":"Boolean","description":"\nWhether to allow selection of more than one row.\n\n"},"progress":{"hasGetter":true,"hasSetter":true,"name":"progress","type":"Boolean","description":"\nWhether to show the progress bar.
