1. pip下載安裝

1.1 pip下載

wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate

我當時用的easy_install,因為我一開始想用 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 安裝

tar -xzvf pip-1.5.4.tar.gz
 cd pip-1.5.4
 python setup.py install

注:Python分為2.x和3.x,這兩個版本目前都有人用,所以,Mac上兩個版本共存應該是明智之舉.系統自帶2.x,我們安裝3.x.怎麼區分這兩個版本呢?想呼叫python 2.x,用python,呼叫pip用pip,而呼叫python 3.x,用python3,pip則用pip3

備註：python setup.py install 執行的時候，有時候需要管理員許可權，如果安裝失敗，嘗試執行sudo +命令
