Visual stdio에서 Workloads가 제대로 설치되지 않았을 때 발생하는 에러입니다.

Solution

언리얼 엔진은 Visual Studio와 통합되어 설계되었기에 visual studio의 환경이 적절히 구성되어야 합니다.

VS를 사용한 언리얼 엔진 개발 시 다음의 Visual Studio Workloads 옵션을 설치해야 합니다.

• .NET desktop development
• Desktop development with C++
• Universal Windows Platform development
• Game development with C++
  
  • 추가로 우측의 Unreal Engine 관련 요소를 설치해주어야 원활한 개발 환경을 구성할 수 있습니다.
