[Ionic] Failed to restore plugin "cordova-plugin-statusbar" 오류 발생 시

ionic serve를 이용해 웹서버 및 페이지를 확인하고, android 에뮬레이터에 올려보려고 했는데, 아래와 같은 에러가 발생하였다.

Failed to restore plugin "cordova-plugin-statusbar" from config.xml. You might need to try adding it again. 
Error: Failed to fetch plugin https://github.com/apache/cordova-plugin-statusbar.git via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

대충 해석을 해보면, cordova-plugin-statusbar라는 플러그인이 뭔가 문제가 있는 것 같다. 

이런 경우 아래 명령어를 통해 해당 플러그인을 추가해주면 된다.

$ cordova plugin add https://github.com/apache/cordova-plugin-statusbar.git
