1、pip下載安裝
1.1 pip下載

# 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

1.2 pip安裝

# 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使用詳解
2.1 pip安裝包

# pip install SomePackage

 [...] Successfully installed SomePackage

# pip install SomePackage

 [...] Successfully installed SomePackage

2.2 pip查看已安裝的包

# 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檢查哪些包需要更新

# pip list --outdated

 SomePackage (Current: 1.0 Latest: 2.0)

# pip list --outdated

 SomePackage (Current: 1.0 Latest: 2.0)

2.4 pip升級(jí)包

# pip install --upgrade SomePackage

 [...] Found existing installation: SomePackage 1.0 Uninstalling SomePackage: Successfully uninstalled SomePackage Running setup.py install for SomePackage Successfully installed SomePackage

# pip install --upgrade SomePackage

 [...] Found existing installation: SomePackage 1.0 Uninstalling SomePackage: Successfully uninstalled SomePackage Running setup.py install for SomePackage Successfully installed SomePackage

2.5 pip卸載包

$ pip uninstall SomePackage

 Uninstalling SomePackage: /my/env/lib/pythonx.x/site-packages/somepackage Proceed (y/n)? y Successfully uninstalled 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國內(nèi)源
python使用pip安裝模塊很方便,可是在國內(nèi)官方源總是會(huì)間歇性的連接不上,其實(shí)python在國內(nèi)也是有安裝源的,比如豆瓣,下面是使用方法.
文件路徑

linux

~/.pip/pip.conf

文件內(nèi)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 安裝：

1.下載get-pip.py 并運(yùn)行

https://bootstrap.pypa.io/get-pip.py

切換到get-pip.py 所在目錄下：python get-pip.py

2.添加環(huán)境變量： 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>添加環(huán)境變量 C:/Python27;C:/Python27/Scripts;
'添加環(huán)境變量' 不是內(nèi)部或外部命令，也不是可運(yùn)行的程序
或批處理文件。

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

Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
