安装python的easy_install和pip

一 安装介绍：

安装地址： https://pypi.python.org/pypi/setuptools#id9

Installation Instructions

The recommended way to bootstrap setuptools on any system is to download ez_setup.py and run it using the target Python environment. Different operating systems have different recommended techniques to accomplish this basic routine, so below are some examples to get you started.Setuptools requires Python 2.6 or later. To install setuptools on Python 2.4 or Python 2.5, use thebootstrap script for Setuptools 1.x.The link provided to ez_setup.py is a bookmark to bootstrap script for the latest known stable release.

window安装：

Windows (Powershell 3 or later)For best results, uninstall previous versions FIRST (see Uninstalling).Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows with PowerShell 3 installed, it’s possible to install with one simple Powershell command. Start up Powershell and paste this command:

> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -

You must start the Powershell with Administrative privileges or you may choose to install a user-local installation:

> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user

If you have Python 3.3 or later, you can use the py command to install to different Python versions. For example, to install to Python 3.3 if you have Python 2.7 installed:

> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -

The recommended way to install setuptools on Windows is to download ez_setup.py and run it. The script will download the appropriate distribution file and install it for you.Once installation is complete, you will find an easy_install program in your Python Scriptssubdirectory. For simple invocation and best results, add this directory to your PATH environment variable, if it is not already present. If you did a user-local install, the Scripts subdirectory is$env:APPDATA\Python\Scripts.Windows (simplified)For Windows without PowerShell 3 or for installation without a command-line, download ez_setup.pyusing your preferred web browser or other technique and “run” that file.

linux安装：

Unix (wget)Most Linux distributions come with wget.Download ez_setup.py and run it using the target Python version. The script will download the appropriate version and install it for you:

> wget https://bootstrap.pypa.io/ez_setup.py -O - | python

Note that you will may need to invoke the command with superuser privileges to install to the system Python:

> wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

Alternatively, Setuptools may be installed to a user-local path:

> wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user

Note that on some older systems (noted on Debian 6 and CentOS 5 installations),wgetmay refuse to downloadez_setup.py, complaining that the certificate common name*.c.ssl.fastly.netdoes not match the host namebootstrap.pypa.io. In addition, theez_setup.pyscript may then encounter similar problems usingwgetinternally to downloadsetuptools-x.y.zip, complaining that the certificate common name ofwww.python.orgdoes not match the host namepypi.python.org. Those are known issues, related to a bug in the older versions ofwget(see Issue 59). If you happen to encounter them, install Setuptools as follows:

> wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py > python ez_setup.py --insecure

mac安装:

Unix including Mac OS X (curl)If your system has curl installed, follow the wget instructions but replace wget with curl and -O with-o. For example:

> curl https://bootstrap.pypa.io/ez_setup.py -o - | python

自定义安装：

Advanced InstallationFor more advanced installation options, such as installing to custom locations or prefixes, download and extract the source tarball from Setuptools on PyPIand run setup.py with any supported distutils and Setuptools options. For example:

setuptools-x.x$ python setup.py install --prefix=/opt/setuptools

Use --help to get a full options list, but we recommend consulting the EasyInstall manual for detailed instructions, especially the section on custom installation locations.
