Npm run deploy failing: permission denied(publickey)

Hello! I am trying to put my React projects on Github Pages with npm run deploy. Everything goes fine with the first stages of npm run build and react scripts build. But then when it gets to this part it fails:

> gh-pages -d build

Cloning into 'C:\Users\User\path\to\file\react-drum-pad\node_modules\.cache\gh-pages\!EdenSweden!react-drum-pad.git'... Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

When I try to debug my ssh key by entering ‘ssh -vT’, it prints this:

So clearly my SSH key is working. I even created a whole new SSH key and that one still isn’t allowing me to complete npm run deploy. What do I do from here? I have followed the troubleshooting steps in the Github documentation, but to no avail.
Could it be because it never asks for my passphrase when running gh-pages -d build?
The SSH folder on my computer has no config file, if that means anything. Just id_rsa,, and known_hosts.

Thank you sooo much for your help. I have been stuck for days. Most online explanations seem to assume I already know Git/Node and don’t explain things clearly at all.

Just in case, have you checked that you are able to pull down the git repository from GitHub? Try to clone into a new folder just to make sure things are hooked up correctly. If you’re able to clone the project then it should mean that your SSH credentials are set up correctly. If that’s the case then it’s possible that npm doesn’t have permission on your computer to read the files in .ssh/.

If you installed npm with sudo then it could cause issues with regards to file permissions.

Thank you for your response. I just tested git clone ‘ssh address’ and it worked. So that’s not the problem. I also never used sudo. Any idea how to check if npm has permission to read the files in /.ssh? I have been using other npm functions just fine (npm start, etc.). It just doesn’t like it when I run gh-pages -d build.

Solution! I did a couple things:

  • Updated to the latest versions of node.js and npm.

  • Navigated to the project I wanted to deploy on my computer, right clicked, selected Git Bash Here and typed ‘npm run deploy’ + enter. Then it actually prompted me for my passphrase, unlike in my code editor terminal.
    Thanks for the help in any case.

Edit: after some issues with installing github pages on npm version 7.23.0, I had to downgrade back to npm version 6.14.15.

Yay! Glad it worked out.
