Answer 1

The MODULE_NOT_FOUND error means it can't find either a package or a file, in this case a package.

Ensure you have the package discord-api-types by doing

npm install discord-api-types

Answer 2

This might be due to npm version.

In old versions, you need to write a flag in command to add the module to dependencies.

npm install <module> --save

Check version, but first check whether that module has been added to dependencies after executing npm install command without flag in package.json file
