Pip: IOError: [Errno 13] 권한 거부: '/usr/local/bin/pip'

• 핍 버전: 1.5.4
• 파이썬 버전: 2.7.6
• 운영 체제: 우분투 14.04

설명:

다음 문제를 어떻게 해결할 수 있습니까?

pip 명령을 통해 autograd 및 scikit-learn 을 설치하려고 했습니다. 그러나 오류와 함께 두 설치 모두 실패했습니다.
OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pip'

따라서 이러한 오류는 pip로 인해 발생할 수 있으므로 업데이트 명령 'pip install -U pip'로 pip를 테스트하고 응답했습니다.
IOError: [Errno 13] Permission denied: '/usr/local/bin/pip'

내 기계의 핍이 고장난 것 같습니까? 어떤 조언이든 감사합니다. 감사합니다.
