Expected behavior Success npm install on build server

Actual behavior

I keep getting the below error on my build step when trying npm install

[npm install] npm ERR! enoent Error while executing:

[npm install] npm ERR! enoent undefined ls-remote -h -t https://oauth2:myaccesstoken@git.mdbootstrap.com/mdb/angular/ng-uikit-pro-standard.git

even though in my package.json my dependency is defined as

"ng-uikit-pro-standard": "git+https://oauth2:myaccesstoken@git.mdbootstrap.com/mdb/angular/ng-uikit-pro-standard.git",

NB: I have removed the access token here

Please kindly assist what i am missing here. Because the npm install works on my local computer however when i take it to build server i get the above error.
