Python: утилита pip для установки пакетов из PyPI

Автор: | 04/29/2014

PythonУ Python имеется собственный «репозиторий» различных пакетов — PyPI (Python Package Index).

Для работы  с ним имеется замечательная утилита — pip.


Для FreeBSD:

# make search key="Python packages"
Port:   py27-pip-1.5.2
Path:   /usr/ports/devel/py-pip
Info:   Tool for installing and managing Python packages
B-deps: gettext- libiconv-1.14_3 py27-setuptools27-2.0.1 python27-2.7.6_4 readline-6.3.3_1
R-deps: gettext- libiconv-1.14_3 py27-setuptools27-2.0.1 python27-2.7.6_4 readline-6.3.3_1
# cd /usr/ports/devel/py-pip && make install clean

Для CentOS:

# yum -y install python-pip

После установки опцией -h можно вывести справку по утилите:

# pip -h
