python中安裝第三方模組

標籤：

Python有兩個封裝了setuptools的包管理工具：easy_install和pip。目前官方推薦使用pip。

現在，讓我們來安裝一個第三方庫——Python Imaging Library，這是Python下非常強大的處理映像的工具庫。一般來說，第三方庫都會在Python官方的pypi.python.org網站註冊，要安裝一個第三方庫，必須Crowdsourced Security Testing道該庫的名稱，可以在官網或者pypi上搜尋，比如Python Imaging Library的名稱叫PIL，因此，安裝Python Imaging Library的命令就是：

pip install PIL

出現如下問題：

Traceback (most recent call last): File “/usr/bin/pip-python”, line 5, in <module> from pkg_resources import load_entry_point File “build/bdist.linux-x86_64/egg/pkg_resources.py”, line 2749, in <module> File “build/bdist.linux-x86_64/egg/pkg_resources.py”, line 444, in _build_master File “build/bdist.linux-x86_64/egg/pkg_resources.py”, line 725, in require File “build/bdist.linux-x86_64/egg/pkg_resources.py”, line 628, in resolve pkg_resources.DistributionNotFound: pip==0.8

出現上述錯誤主要是由於python的版本太過老了，需要下載最新版本的setuptools

 無奈之下，只好去安裝easy_install並安裝。

easy_install PIL
