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.

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
Installing collected packages: pycurl
Successfully installed pycurl-7.19.5.1
C:\Users\admin>pip install --upgrade ovirt-engine-sdk-python
Collecting ovirt-engine-sdk-python
Using cached ovirt-engine-sdk-python-3.6.0.3.tar.gz
Collecting lxml>=2.2.3 (from ovirt-engine-sdk-python)

Collecting pycurl>=7.19.0 (from ovirt-engine-sdk-python)

Complete output from command python setup.py egg_info:

----------------------------------------

1.pen\appdata\local\temp\pip-build-owiy_9\pycurl
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
Using cached ovirt-engine-sdk-python-3.6.0.3.tar.gz
