Question

我的代码需要帮助。我正在构建不和谐的机器人。我不知道我的代码有什么问题，但是它给出了

TypeError：无法读取未定义的属性“发送”

if(receivedMessage.content.startsWith("!")) {
    processCommand(receivedMessage)
}

function processCommand(receivedMessage) {
    let fullCommand = receivedMessage.content.substr(1)
    let splitCommand = fullCommand.split(" ")
    let primaryCommand = splitCommand[0]
    let arguments = splitCommand.slice(1)

    if (primaryCommand == "help") {
        helpCommand(arguments, receivedMessage)
    }
}


function helpCommand(arguments, receivedMessage){
    if (arguments.length == 0) {
        receivedMessage.channnel.send("Im not sure what are you looking for.Try 
using `!help [topic]`")
    } else {
        receivedMessage.channel.send("It looks like you need help with " + arguments)
    }
}

Answer 1

TypeError: Cannot read property 'send' of undefined告诉您receivedMessage.channnel是未定义的，当您在行中仔细查看时：

  receivedMessage.channnel.send("Im not sure what are you looking for.Try using `!help [topic]`")

您应注意，您所做的是cha nnn el而不是channel
