Build fails at Angular Tree component with message "no exported member 'Cancelable'"


I use Angular Tree Component in my project and for the past couple of days, I get the following error while building the Angular application. The issue was resolved after quiet a struggle. I am posting my answer below for the community.

Solution

  • The latest version of loadash (4.14.161) has a breaking change. Stick to versions below 161 and things will work. The Angular-tree-component uses lodash internally. I was having a cap on my lodash version which updated the component automatically making it more difficult to find.

    Changed "@types/lodash": "^4.14.119",

    to "@types/lodash": "4.14.119",
