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(dāng)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 pipHomebrew PRovides pip via: *brew install python*. However you will thenhave two Pythons installed on your Mac, so alternatively you can: sudo easy_install pipsudo easy_install pip1.2 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(yīng)該是明智之舉.系統(tǒng)自帶2.x,我們安裝3.x.怎么區(qū)分這兩個版本呢?想調(diào)用python 2.x,用python,調(diào)用pip用pip,而調(diào)用python 3.x,用python3,pip則用pip3,以此區(qū)分.
備注：python setup.py install 執(zhí)行的時候，有時候需要管理員權(quán)限，如果安裝失敗，嘗試執(zhí)行sudo +命令
