Discord Bot Help (First Timer)

Hi! I am trying to make a discord bot following this tutorial. All is good until step 10. It tells me to run this command:

node bot.js

It gives me this in response:

C:\Users\JesseR\Desktop\DiscordBot\node_modules\discord.i\lib\index.js:1906
old = copy(client.servers[_data.guild_id].members[_data.user.id]);
^

TypeError: Cannot read property ‘775799584165068810’ of undefined

I assumed it means it works, but when I type !intro, nothing happens. This is my only problem. Any help would be appreciated! Thanks!

EDIT: There are also a couple “discord.i o” (no space in there." I simply removed their O’s in this post as they count as links, they do have the O’s in the code.
