I am currently working on an Angular 6 project and encountering an issue when trying to execute the command npm run build. The error message I am facing is displayed below:
ERROR in node_modules/rxjs/internal/symbol/observable.d.ts(4,9): error TS2687: All declarations of 'observable' must have identical modifiers.
node_modules/@types/node/index.d.ts(167,14): error TS2687: All declarations of 'observable' must have identical modifiers.
