[Vue.js] URIError: Failed to decode param ‘/%3C%=BASE_URL%20%%3Efavicon.ico’ 오류가 발생한다.

아니 왜, 갑자기 favicon.ico 관련 URI오류가 발생하는 것일까??

URIError: Failed to decode param '/%3C%=BASE_URL%20%%3Efavicon.ico'

나와 같은 이슈가 발생한 개발자들…..

https://github.com/vuejs/vue-cli/issues/2357

https://github.com/vuejs/vue-cli/issues/1451

아직 해결책을 찾지 못했다. 

또 다른 오류 이슈!!

Proxy error: Could not proxy request /selectUserModel.do from localhost:8080 to http://localhost:3000/.

오류도 발생한다. 뭐냐 이거!!

[해결방법]

비주얼스튜디오 코드에서 vue 파일을 수정하면  다시 컴파일되면서 Apll running at: URL주소가 노출되면서 정상으로 복구되었다. 복구가 되지 않는다면 package.json 파일에서 proxy설정을 추가해주면 되는 것 같다. 자세한 내용은 스택오버플로어사이트링크를 참고!!
