I am in process migrating Angular 5 project to Angular 6.
While starting application by
npm start
getting the below error
Relative path ../
used to go back one directory. So, first check the file path, if its not contain your project root folder you are searching that jquery file somewhere else that even not exist.
If node_modules file and angular.json both in same directory you donot need to use relative path.
In Angular 6, you donot need to use relative path to go inside node_modules from angular.json(../
or even like ./
).
