使用pip来管理python包
2015/12/8
一、安装pip 【Linux】 yum install python-pip 【Win】 安装python时，默认已经安装pip 二、使用pip安装包 【Linux】 [root@tvm-test ~]# pip install Django==1.6.0 Collecting Django==1.6.0 /usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning. InsecurePlatformWarning Downloading Django-1.6-py2.py3-none-any.whl (6.7MB) 100% |████████████████████████████████| 6.7MB 74kB/s Installing collected packages: Django Successfully installed Django-1.6 [root@tvm-test ~]# python -c "import django;print(django.get_version())" 1.6 【Win】 D:\apps\Python34\Scripts>pip install Django You are using pip version 6.0.8, however version 7.1.0 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
