Python库管理工具pip在Mac上安装卸载

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.

备注:python setup.py install 执行的时候,有时候需要管理员权限,如果安装失败,尝试执行sudo +命令
