2. 해결을 위해 설치한 패키지

  • 설치되어 있던 패키지도 삭제 후 재설치 시도
$ yum -y install gcc gcc-c++ kernel-devel
$ yum -y install python-devel libxslt-devel libffi-devel openssl-devel
  • EPEL 패키지 repository
  • https://fedoraproject.org/wiki/EPEL
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
  • python34-devel 패키지 설치
yum install python34-devel
