NPM install hangs on stage:loadCurrentTree - npm

Question

I have a package on npm that links to git+ssh://git#bitbucket.org/own-repository/coreee.git#release-2.0
It hangs very often. Occasionally it will install fast, but more often i must wait like idk, 15 minutes before it started. It was stuck on this line:
⸨░░░░░░░░░░░░░░░░░░⸩ ⠧ rollbackFailedOptional: verb npm-session 353d0cde074aa46d
npm config list give me this:
; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.9.0 node/v10.15.0 darwin x64"
; userconfig /Users/me/.npmrc

; node bin location = /Users/me/.nvm/versions/node/v10.15.0/bin/node
