Express API using babel, express app won't start due to wrong version of Babel

Error message:

Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of #babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "#babel/core" or "babel-core" to see what is calling Babel.

What is also important to say is that I do not host the Database on my PC, I have rented a server for it. Hope that someone can help

I am not getting what type of these errors are and why I am getting them.

In the terminal you should do node tut64.js
And check the path of tut64.txt or post your code.

Cannot find module 'discord.js'

When I start my discord bot I get an error on the console:
internal/modules/cjs/loader.js:834
throw err;
^
Error: Cannot find module 'discord.js'

But if there is an "index.js"

You need to install discord.js, in your console type npm install discord.js
