Exit status 1 on npm run build

I followed the instructions in this video https://www.youtube.com/watch?v=cVyA2v-UwSQ. Even using the older npm nvm install 14.16.1 && node -v > .nvmrc command as was shown in the video.

And everything was going fine until I got to npm run build.

Here is the error that displayed in terminal, and I'll paste the npm log as well.
