일부 패키지 설치시 오류가 발생할 수 있다. 패키지 내에 c/c++ 라이브러리를 설치하는 경우 권한에 따른 에러가 발생하게 된다.
sentry 역시 그렇다. 로컬에선 별 문제 없다가 aws에서 문제가 발생한다. 

설치 과정에서 추적하다보면 node scripts/install.js 라인에서 발생하고, 해당 디버그 메세지는 아래와 같다.

Here is my recipe how to speed up your lovely WebStorm:

Go to Preferences and do next:

Appearance & Behaviour > System Settings > Usage Statistics: Uncheck Allow sending data usage statistics to JetBrains
Editor > Live Templates: disable all, leave only what you are really use
Editor > Emmet: disable all emmets
Editor > Intentions: I leave only: CSS, Declaration, JavaScript and Language Injection
