Can I just upload files using FTP, I can't really access the command line on my website.
Refer to the documentation, it'll likely be in there. Link to Documentation
You probably could FTP the files to a location, but you'll need SSH to run the installer and start the app.
Someone at another forum suggested I edit registry entry to change the default path from that invalid path. I did, and it worked.
I think this question does not belong in this forum. Try a general google first.
@Justin-Kamerman-0 sudo service mongod start
@roy.miller how much memory does your DO droplet have? It could be that the npm install is running out of memory, but that's unlikely.
Try running npm ls after running npm install --production. Those npm warnings are not errors. You can ignore them.
Tomorrow i can test it at school, at home it says it works.
