1、pip下载安装
1.1 pip下载
# wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate # wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate

# tar -xzvf pip-1.5.4.tar.gz # cd pip-1.5.4 # python setup.py install # tar -xzvf pip-1.5.4.tar.gz # cd pip-1.5.4 # python setup.py install
2. pip使用详解
2.1 pip安装包
# pip install SomePackage
[...] Successfully installed SomePackage
# pip install SomePackage
[...] Successfully installed SomePackage
2.2 pip查看已安装的包
# pip show --files SomePackage
Name: SomePackage Version: 1.0 Location: /my/env/lib/pythonx.x/site-packages Files: ../somepackage/__init__.py [...]
# pip show --files SomePackage
Name: SomePackage Version: 1.0 Location: /my/env/lib/pythonx.x/site-packages Files: ../somepackage/__init__.py [...]
2.3 pip检查哪些包需要更新
# pip list --outdated
SomePackage (Current: 1.0 Latest: 2.0)
# pip list --outdated
SomePackage (Current: 1.0 Latest: 2.0)
2.4 pip升级包
# pip install --upgrade SomePackage

$ pip uninstall SomePackage
Uninstalling SomePackage: /my/env/lib/pythonx.x/site-packages/somepackage Proceed (y/n)? y Successfully uninstalled SomePackage
3.使用pip国内源
python使用pip安装模块很方便,可是在国内官方源总是会间歇性的连接不上,其实python在国内也是有安装源的,比如豆瓣,下面是使用方法.
文件路径
linux
~/.pip/pip.conf
文件内容
[global] index-url = http://pypi.douban.com/simple trusted-host = pypi.douban.com
或者使用-i指令:
easy_install -i http://pypi.douban.com/simple/ saltTesting pip install -i http://pypi.douban.com/simple/ saltTesting
pip 安装：
1.下载get-pip.py 并运行
https://bootstrap.pypa.io/get-pip.py
切换到get-pip.py 所在目录下 ：python get-pip.py
2.添加环境变量： C:\Python27\Scripts;
C:\Users\Administrator>python --version
Python 2.7.8
C:\Users\Administrator>pip --version
pip 1.5.6 from C:\Python27\lib\site-packages (python 2.7)
C:\Users\Administrator>添加环境变量 C:\Python27;C:\Python27\Scripts;
'添加环境变量' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
C:\Users\Administrator>pip install selenium
Requirement already satisfied (use --upgrade to upgrade): selenium in c:\python2
7\lib\site-packages
Cleaning up...
C:\Users\Administrator>python
Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win
32
Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
