我正在尝试执行我在github上找到的脚本，该脚本可以解析电子邮件并将其从gmail帐户追加到Google工作表中。
https://github.com/jimi985/RSVP-Google-App-Script
我运行AddRSVPToSpreadsheet的错误是
TypeError：无法调用未定义的方法“ toArray”。 （第154行，文件“代码”）
我正在逐步运行这些功能，并且已经通过电子邮件发送了示例文本，添加了gsheets字符串，并允许脚本访问电子邮件帐户。
电子邮件标签也是；婚礼回复副总裁
是我运行这些功能的顺序吗？
RSVP 初始化电子表格 处理器vps addrsvpstospreadsheet
有特殊命令吗？ 当我选择运行功能时，此顺序会在应用脚本界面中列出。
有人能指出我正确的方向吗？或解释为什么我会收到此错误？

答案 0 :(得分：0)
您无法从编辑器的运行菜单中运行功能addRSVPToSpreadsheet，因为它需要参数rsvp。您收到的错误是因为运行菜单尝试运行addRSVPToSpreadsheet()，即没有rsvp参数。为rsvp分配了值undefined，因此undefined.toArray()会导致您看到错误。
运行菜单中的顺序仅是功能在当前脚本文件中出现的顺序。这并不意味着您应该按此顺序运行它们。
脚本的入口点似乎是最后一行
processRSVPs(RSVP_LABEL);
如果要在运行菜单中调用该行，则需要添加驱动程序功能，例如
function startProcess() {
processRSVPs(RSVP_LABEL);
}
