Hi @Tamirlan Alibekov ,
It seems the typescript is an out-of-date version. Please check the version of the TypeScript by tsc -v . You can try to update to the latest TypeScript by following cmdlet to resolve the issue.

npm uninstall -g typescript  
npm install typescript --save-dev  
Check your package.json to ensure you're using a current version of the typescript package

Thank you so much @Yasser Dabhoiwala  . I have successfully solved my problem. I can't get out from error.     

But when came to your comment and apply it to my project my error is gone.

Hi @Akshay koul   ,    
As I've mentioned in my reply above, react-router-dom won't work with the latest version, but you'll need to target version 5.3.0:    
npm i react-router-dom@5.3.0    

npm i @types/react-router-dom    
In your case you'll need to first uninstall your installed version of react-router-dom.    
Let me know how you go?
