Python detailed installation pip tutorial

First install Python

I have installed two versions:

Python-2.7.10.tgz

Python-3.5.1.tgz

First look at the Python version that comes with the system:

1 [email protected] src]# python-v 2 Python 2.6.6

To install the Python2.7 version:

[Email protected] src]# tar zxvf python-2.7.10.tgz [[email protected] src]# CD Python-2.7.10[[email protected] Python-2.7 .10]#./configure--prefix=/usr/local/python27[[email protected] python-2.7.10]# make && make install

Back up the original Python version:

[Email protected] python-2.7.10]# Mv/usr/bin/python/usr/bin/python_old

To establish a Python2.7 soft connection:

1 [email protected] python-2.7.10]# ln-s/usr/local/python27/bin/python/usr/bin/python 2 [email protected] python-2.7.10]# python-v 3 Python 2.7.10

To install the Python3.5 version:

12[[email protected] src]# CD Python-3.5.13[[email protected] python-3.5.1]#./configure--prefix=/usr/local/python34[[email protected] python-3.5.1]# make && make install5[[email protected] python-3.5.1]# ln-s/usr/local/python3/bin/python3/usr/ Bin/python36[[email protected] python-3.5.1]# python3-v7 Python 3.5.1

Start installing PIP

First download PIP:

1 [[email protected] src]# wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5= 834B2904F92D46AAA333267FB1C922BB "--no-check-certificate

Unzip the installation:

12[[email protected] src]# CD pip-1.5.43[[email protected] pip-1.5.4]# Python setup.py install4Traceback (most recent):5   <  Module>6from    setuptools Import setup, find_packages7 Importerror:no module named Setuptools

See "Importerror:no module named Setuptools", missing Setuptools module

Download and install the Setuptools module:

[Email protected] src]# wget--no-check-certificate https://pypi.python.org/packages/source/s/setuptools/ setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65 [[email protected] src]# tar zxvf setuptools-12.0.3.tar.gz [[email protected] setuptools-12.0.3]# python setup.py build[[email protected] setuptools-12.0.3]# python setup.py install***z = ZipFile. ZipFile (zip_filename, Mode, compression=compression)  File "/usr/local/python27/lib/python2.7/zipfile.py", line  736, in __init__    "Compression requires the (missing) zlib module" Runtimeerror:compression requires the (missing) zlib Module

See the missing zlib module, workaround:

[email protected] setuptools-12.0.3]# Yum install zlib zlib-devel

Python2.7 and 3.5 will need to be recompiled after the installation is complete:

[Email protected] setuptools-12.0.3]# CD. /python-2.7.10[[email protected] python-2.7.10]#./configure--prefix=/usr/local/python27/[[email Protected] python-2.7.10]# make && make Install[[email protected] python-2.7.10]# Rm-rf/usr/bin/python[[email protected] P ython-2.7.10]# Rm-rf/usr/bin/python3[[email protected] python-2.7.10]# ln-s/usr/local/python27/bin/python/usr/bin/ Python[[email protected] python-2.7.10]# CD. /setuptools-12.0.3[[email protected] setuptools-12.0.3]# python setup.py buildrunning buildrunning build_py[[email Protected] setuptools-12.0.3]# python setup.py install***processing dependencies for setuptools==12.0.3finished Processing dependencies for setuptools==12.0.3

After the reinstallation, it succeeded! But now just put the setuptools installed, in the re-install PIP:

[[email protected] pip-1.5.4]# python setup.py install

Installed/usr/local/python27/lib/python2.7/site-packages/pip-1.5.4-py2.7.egg
Processing dependencies for pip==1.5.4
Finished processing dependencies for pip==1.5.4

[[email protected] pip-1.5.4]# python-m pip Install a

/usr/bin/python:cannot Import name Httpshandler; ' Pip ' is a package and cannot be directly executed

According to the above prompt is also missing Httpshandler module, installation:

[email protected] ~]# Yum install OpenSSL openssl-devel-y

Then reinstall the Python and install the PIP when the installation is complete:

[ [email protected] ~]# Pythonpython 2.7.10 (default, APR, 11:43:29) [GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on  Linux2type "Help", "copyright", "credits" or "license" for more information.>>> import virtualenvtraceback (most Recent call last): File "<stdin>", line 1, in<Module>Importerror:no module named Virtualenv>>> exit () [[email protected] ~]# python-m pip install virtualenvdownl oading/unpacking virtualenv downloading VIRTUALENV-15.0.1-PY2.PY3-NONE-ANY.WHL (1.8MB): 1.8MB downloadedInstalling Collected packages:virtualenvsuccessfully installed virtualenvcleaning up ...

~ok, it's been a success!

If the installation is not a problem is the best, so when installing the software, you must first install the dependency package!
