Upon a fresh install under Ubuntu 20 using npm install -g verdaccio-bitbucket and the default auth config, once launching verdaccio it fails with the following error:

 error--- error loading a plugin bitbucket: { Error: Cannot find module '/usr/local/lib/node_modules/verdaccio-bitbucket/node_modules/bcrypt/lib/binding/bcrypt_lib.node'

This is resolved by:

$ sudo su -
$ cd /usr/local/lib/node_modules/verdaccio-bitbucket/node_modules
$ npm rebuild bcrypt

Then verdaccio successfully launches:

$ verdaccio
 warn --- config file  - /home/ubuntu/verdaccio/config.yaml
 warn --- Verdaccio started
 warn --- Plugin successfully loaded: verdaccio-bitbucket
 warn --- Plugin successfully loaded: verdaccio-audit
