如何安装Python下的常用下载工具pip？
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
1.2 pip安装
# 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# pip list --outdated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# pip list --outdated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
[...] 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卸载包
$ 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
