I have also faced the same issue,
- This issue is specific to typescript version
- Perform below steps to remove it ( It worked for me)
- In your project, inside package.json file - verify that you have typescript under the dependencies
devDependencies{
"typescript": "^2.5.2"
}
- check the installed version of the typescript on your system by typing tsc -version command in terminal
- this will show the installed version of typescript at global level
- o/p version - 2.9.1
- Change version number insider package.json file with the version installed on your system.
devDependencies{
"typescript": "^2.9.1"
}
Hope this will work!!!!!!!!!!!!
