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.

三、其他用法
指定版本号安装：
pip install Django==1.6.0
卸载：
pip install Django
从文本文件中安装指定的包：
pip install -r requirements.txt
pip freeze >requirements.txt
四、版本问题
1、在windows下安装 ovirt-engine-sdk-python 时遇到异常：
# pip install ovirt-engine-sdk-python
Please specify --curl-dir=/path/to/built/libcurl
pycurl异常，，官网是win32的版本，安装后，后续使用可能会报错：
pycurl DLL load failed: %1 不是有效的 Win32 应用程序。
可以在这里找到amd64的版本，然后用pip手动安装：
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pycurl
假设下载后，路径为：D:/pycurl-7.19.5.1-cp27-none-win_amd64.whl
安装：
C:\Users\admin>pip install D:/pycurl-7.19.5.1-cp27-none-win_amd64.whl
Processing d:\pycurl-7.19.5.1-cp27-none-win_amd64.whl
Installing collected packages: pycurl
Successfully installed pycurl-7.19.5.1
2、升级
pip install --upgrade ovirt-engine-sdk-python
如果又遇到pycurl异常的提示，，
C:\Users\admin>pip install D:/pycurl-7.19.5.1-cp27-none-win_amd64.whl
Processing d:\pycurl-7.19.5.1-cp27-none-win_amd64.whl

则尝试 uninstall ovirt-engine-sdk-python 再重新install
C:\Users\admin>pip install ovirt-engine-sdk-python
Collecting ovirt-engine-sdk-python
