Take a look at #178 (same issue). A downgrade will resolve the issue if you aren't using anything specific to the newer versions. I downgraded from 0.2.9 -> 0.2.6 and it fixed my build issues.

naveenksamala commented 4 years ago

Yes, downgrading to version 0.2.3 worked for me. 0.2.6 and 0.2.10 both did not work with angular 7.3.9.

ottokruse commented 4 years ago

Same issue here. 0.2.3 works

neuronraptor commented 4 years ago

Same issue here. 0.2.3 works

I successfully got rid of this issue by excluding all test dependencies and now it works as am intended even under angular 9.0.3. Finally, I took the latest version 0.2.10 and cut off all test dependencies. That's it! :)

How did you remove the test dependencies?

naveenksamala commented 4 years ago

@jltrevizon, @anshumandikshit, give this a try, delete node_modules and package-lock.json, do a npm install and build the project. npm install will do a clean install of all packages and also creates a new package-lock.json. See if this fixes the issue you are facing.

Nitin-Daddikar commented 4 years ago

To solve this remove the caret ^ symbol ie "ng-multiselect-dropdown": "^0.2.3" to "ng-multiselect-dropdown": "0.2.3" OR "ng-multiselect-dropdown": "^0.2.4" to "ng-multiselect-dropdown": "0.2.4"
