這篇文章主要介紹了Python下的常用下載安裝工具pip的安裝方法,注意在Python2.7.9和3.4以上默認已經(jīng)集成了pip,需要的朋友可以參考下

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# pip list --outdated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# pip list --outdated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)官方源總是會間歇性的連接不上,其實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
32
Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
