Unknown issue with npm packages

Not sure if this is a Glitch or Discord.js problem, but it’s only happening on afk-elevator so I think it might be Glitch.

I’m getting this error:

throw err;

Error: Cannot find module 'snekfetch'

When I try to add snekfetch to package.json, I get this:

node v8.15.1, with pnpm
Installing...
 WARN  deprecated snekfetch@4.0.4: use node-fetch instead

Try pnpm install snekfetch -u
