031. Raspberry Pi 라즈베리 파이 - PhantomJS, CasperJS 설치

Headless기술에 관심이 생겨 PhantomJS, CasperJS를 설치했습니다

기본적으로 NPM을 사용해서 설치가 가능하지만

 

• NPM 으로 PhantomJS 설치 시 에러..

근데 NodeJS (v7.9.0)를 언제 설치한거지..?

PhantomJS는 NPM설치시 에러가 발생하니 github에 올라와있는걸 사용했습니다

 

NPM이나 NodeJS를 모른다면 이야기가 달라지겠지만..

Raspbian Jessie에는 nodejs v0.10.29 이 이미 설치되있습니다

근데 NPM은 설치가 안되있으니 설치해야...

 

NPM만 설치하려면(nodejs는 재 설치 해봐야 v0.10.29)

sudo apt-get update && sudo apt-get install npm -y

하시면 됩니다 v1.4.21 이 설치되구요

 

nodejs나 npm을 좀더 최신으로 설치하려면

친절하게도 PhantomJS를 PI로 build한걸 배포하는걸 이용했습니다

build 환경 맞추는것도 그렇고.. 번거로운걸 안해도 되니 편합니다

 

• PhantomJS

• 실행환경 구성

pi@rasp2-dev:~/utils $ sudo mv phantomjs-raspberrypi /usr/local/ pi@rasp2-dev:~/utils $ sudo ln -s /usr/local/phantomjs-raspberrypi/bin/phantomjs /usr/bin/ pi@rasp2-dev:~/utils $ ph phantomjs   phar5       php5        php5enmod    phar        php         php5dismod  php5query pi@rasp2-dev:~/utils $ phantomjs -v 1.9.8

웬만한건 전부 /usr/local/ 에 옮겨놓고 쓰고있으니..

역시나 /usr/local/ 로 옮겨줍니다

 

path 변경하는건 귀찮으니 시스템 path에 링크를 걸어줍니다

/usr/bin/ 에 링크걸어주면 됩니다

ph만 쓰고 탭(Tab)키를 눌러주면 phantomjs 가 리스트로 보이네요

버전은 1.9.8로 최신(2.1.1)은 아닙니다

 

최신으로 설치하고 싶으시면 Phantomjs build 페이지(http://phantomjs.org/build.html)를

참고하시면 됩니다만.. 추천해 드리진 않습니다..  삽질만 할테니까요

하드웨어 요구사항만 봐도 RAM 4G, CPU 1.8GHz 등등

 

• CasperJS

NPM으로 설치해도 됩니다

pi@rasp2-dev:~/utils $ npm install casperjs -g /usr/local/node-v7.9.0/bin/casperjs -> /usr/local/node-v7.9.0/lib/node_modules/casperjs/bin/casperjs /usr/local/node-v7.9.0/lib └── casperjs@1.1.4

CasperJS 는 깔끔하게 끝
