Question

运行cordova requirements browser命令时，出现错误说明：错误：无法读取属性＆＃39; forEach＆＃39;未定义的。它没有告诉我错误源自何处，也没有--debug属性的要求。就我而言，这个错误可能来自我项目中的任何文件...

Answer 1

您可以安装cordova 8.1.2，它将显示带有-d的堆栈跟踪，例如：

$ cordova requirements -d
PlatformApi successfully found for platform browser
PlatformApi successfully found for platform ios

Requirements check results for browser:
Cannot read property 'forEach' of undefined
TypeError: Cannot read property 'forEach' of undefined
