Compiling Ipython with Python27
/usr/local/python27/bin/python2.7 setup.py Build
Compilation successfully performed installation
/usr/local/python27/bin/python2.7 setup.py Install


If the installation succeeds, there is a Ipython file under the/usr/local/python27/bin directory
ls/usr/local/python27/bin/

installation of centos6.5 environment python3.5

To install dependent dependencies:

Yum-y install XZ wget gcc make gdbm-devel openssl-devel sqlite-devel zlib-devel bzip2-devel

Install Python3:

wget HTTP://MIRRORS.SOHU.COM/PYTHON/3.5.2/PYTHON-3.5.2.TAR.XZ

TAR-XF PYTHON-3.5.2.TAR.XZ

CD Python-3.5.2

./configure--enable-shared--enable-loadable-sqlite-extensions--with-zlib

Make && make install

Add Python3 command:

Ln-sv/usr/local/bin/python3.5/usr/bin/python3

Vim/etc/ld.so.conf

/usr/local/lib # New Library file path
Include ld.so.conf.d/*.conf

# Make the Configuration library effective
/sbin/ldconfig

Version detection
# python3-v
Python 3.5.2


Run Python3 directly in the future and you can execute the command via the python3.5.2 version.
