Hi ,

I just reproduced the same issue :

• MacOs Mojave (version 10.14.6)
• Chrome Version 80.0.3987.163

I thins it’s a compatibility issue with Rxjs and angular see https://stackoverflow.com/questions/50316141/ng-select-in-angular5-issue-error-typeerror-object-is-not-a-function-at

The given solution worked for me : npm i -s @ng-select/ng-select@latest rxjs-compat

closing as it seems to be a dependency issue, please contact @kacperknapik if it persists
