node_modules/rxjs/internal/types.d.ts(81,44): error TS1005: ';' expected error after installation of Angular 6

 If you I got an error node_modules/rxjs/internal/types.d.ts(81,44): error TS1005: ';' expected solution is as below 

You need to do some changes in package.json.

Go to package.json and modify "rxjs": "^6.0.0" to "rxjs": "6.0.0"Then run npm update in your project.

Thank you ,
