python安裝setuptools步驟詳解

Python中當需要安裝第三方python包時，可能會用到easy_install命令。easy_install是由PEAK(Python Enterprise Application Kit)開發的setuptools包裡帶的一個命令，所以使用easy_install實際上是在調用setuptools來完成安裝模組的工作。

為了方便後續安裝各種第三方python包，需要先安裝setuptools。

安裝setuptools的話，下面一條簡單的命令就可以搞定，指令碼會自動為你安裝適合你系統的對應版本。

代碼如下	複製代碼
# wget https://bootstrap.pypa.io/ez_setup.py -O - | python

大部分情況下，上面的命令都可以完成setuptools的安裝，不過我在CentOS系統中安裝setuptools的時候，貌似沒那麼順利呢，所以我的解決辦法如下：

自動安裝指令碼需要去下載一個檔案，可是下載不下來，卡在Downloading這裡了，只好改成手動方式下載了

代碼如下

下面把自動安裝指令碼也下載下來，讓這個指令碼替我們去安裝
