pip安装使用详解
1. pip下载安装
1.1 pip下载
wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate
我当时用的easy_install,因为我一开始想用 homebrew, homebrew 提醒我可以用 easy_install
brew info pip
Homebrew provides pip via: *brew install python*. However you will then
have two Pythons installed on your Mac, so alternatively you can:
sudo easy_install pip
sudo easy_install pip
1.2 pip 安装
tar -xzvf pip-1.5.4.tar.gz
cd pip-1.5.4
python setup.py install
注:Python分为2.x和3.x,这两个版本目前都有人用,所以,Mac上两个版本共存应该是明智之举.系统自带2.x,我们安装3.x.怎么区分这两个版本呢?想调用python 2.x,用python,调用pip用pip,而调用python 3.x,用python3,pip则用pip3,以此区分.
