Discord.MessageEmbed 不是构造函数

Question

所以最近我尝试在我的不和谐机器人中添加一个命令处理程序。所有具有 Embeds 的命令都会出现错误“Discord.MessageEmbed 不是构造函数”。

\n

仅当我添加命令处理程序时才会发生这种情况，但如果没有它，命令也可以正常工作。

更新：如果您使用的是 v14 并收到上述错误，那是因为MessageEmbedis now EmbedBuilder。有关更多信息，您可以查看此答案：Discord.js v13 code Breaks when Upgrade to v14。

看来您（没有）将Discord变量传递给您的execute方法并混合new Discord.MessageEmbed()and （您正在使用的new MessageEmbed()变量）。尝试全部替换为，它应该可以工作。requirediscord-jsnew Discord.MessageEmbed()newMessageEmbed()

其他选项是检查如何调用execute主文件中的方法。如果您Discord作为第三个参数传递，则不需要const { MessageEmbed } = require(\'discord.js\');在顶部使用，而只需new Discord.MessageEmbed()在各处使用 s 。
