What have you tried? What issue are you having? There's too little information to go off of– Canadian LukeJun 27, 2014 at 1:21
Hi Canadian Luke! Thanks for your comment! The question is that! Very objective and specific! I can not imagine what more I can add... Below I answer what I ask! I hope that I have been helpful to this community that I so appreciate! =D– Eduardo LucioJun 27, 2014 at 2:35
Install Python 3.2.2 (CentOS 6.5 AMD64):
In order to compile Python you must first install the development tools and a few extra libs. The extra libs are not strictly needed to compile Python but without them your new Python interpreter will be quite useless
sudo yum groupinstall "Development tools" sudo yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
Here are the commands to download, compile and install Python
cd /usr/local/src sudo wget http://python.org/ftp/python/3.2.2/Python-3.2.2.tar.xz --no-check-certificate sudo tar xf Python-3.2.2.tar.xz cd Python-3.2.2 sudo ./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" sudo make && sudo make altinstall
After running the commands above your newly installed Python interpreter will be available as /usr/local/bin/python3.2
Download and install Setuptools + pip
cd /usr/local/src sudo wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py sudo /usr/local/bin/python3.2 ez_setup.py sudo /usr/local/bin/easy_install-3.2 pip
Create your isolated Python 3.2 environment
sudo /usr/local/bin/pip3.2 install virtualenv sudo /usr/local/bin/virtualenv /usr/local/virtenv3.2 cd /usr/local/virtenv3.2 source bin/activate python --version # (To check version)
It worked perfectly with Python 3.4 by replacing "3.2" with "3.4" and the Python-3.2.2.tar.xz URL with the 3.4 URL :)– sromeroJul 22, 2015 at 13:28
