Read timed out
다운로드 시간이 초과되었습니다. 중국 네트워크가 그렇습니다. 프로그래머가 되는 것은 정말 쉽지 않습니다.
pip 소스만 수정하세요.
임시 사용: pip install pythonModuleName -i https://pypi.douban.com/simple
기본 소프트웨어 소스 수정:
/etc/pip.conf 파일을 수정하여 모든 사용자에 대해 구성합니다.
~/.pip/pip.conf을 현재 사용자 구성으로 수정합니다.
windows 아래의 pip 구성 파일은 C:Usersxxpippip.ini입니다. 그렇지 않은 경우 새로 만드세요.

현재 일반적으로 사용되는 소스는 다음과 같습니다.

• 청화대학교 http://pypi.tuna.tsinghua.edu...

• 중국과학기술대학교 https://pypi.mirrors.ustc.edu...
