Hello I'm building first Angular Application . I'm creating a new angular application using this command ng new purchase-section. But when I executing the application using ng serve -o I got this error .

ERROR in node_modules/rxjs/internal/types.d.ts(81,44): error TS1005:
';' expected. node_modules/rxjs/internal/types.d.ts(81,74): error
TS1005: ';' expected. node_modules/rxjs/internal/types.d.ts(81,77):
error TS1109: Expression expected.

I have inspected types.d.ts as I know it is created by angular .
I'm not able to understand the error . Please note that after I got this error I deleted node_modules and I install using npm install wished i got away still I got this error . Your help will be highly appreciated.
Here is My package.JSON code

                "typescript": "~2.7.2"

                 }

               }

Just remove ^ from "rxjs": "^6.0.0" from package.json and make it "rxjs": "6.0.0" and it should work fine.

@Rifat Murtuza I had the same issue. I investigated that rxjs released a new version 6.4.0. And it brokes the build. According to review, the minimum supported version of TypeScript is 2.8. If you don't want to update TypeScript version, just change "rxjs": "^6.0.0", to "rxjs": "6.3.3" in package.json.

I was facing the same issue while developing an angular6 project. I spent more time finally it's working for me.
Here is the solution:

1. Open "package.json"2


2. 
   

   "rxjs" and "typescript" verstion like below screenshot

   
   
   

   

   
   



3. Change like below screenshot
   




4. Next go to your project folder and delete "node_modules" folder.



5. After delete next run "npm install" in your project folder


6. Finally run "ng serve". It should work (I tried 3 projects and confirmed)

Same issue here..
All i did is creating a new project and started it by typing in ng serve

*edit
just updated my typescript verision - everything works fine now.

Seems like your angular and/or rxjs version is not compatible with typescript. Remove the ~ sign in the typescript version, add ^ instead. Then install packages again.
Try running 'npm start' and 'ng build' prior to 'ng serve'.
