NPM Install Discogs extension on Heroku deploy does not work

With the latest fixes to update packages I am able to deploy successfully to Heroku now, thank you. However, I wish to use the Discogs extension.

The installation details state to just run `npm install graphbrainz-extension-discogs` but doing so on the Heroku console results in a lot of console logs stating `Integrity checksum failed when using sha1....` and listing Discogs as an extension in the config vars does not work, probably because it cannot find it if it was installed.

How could I go about installing and using this extension? I would create a discussion on this topic and not an issue but I do not see this option for the repo. Thank you in advance!
