First, install python2.6 executable. see previous post if you have issues when compiling (gcc not found).
Make sure you have installed python-dev with apt-get or yum.
Then, following the instructions on the same topic but for Python 3 in a virtualenv,
virtualenv --python=/home/<user>/Software/Python2.6/mybuild/bin/python2.6 virtualenv2.6 --no-setuptools cd virtualenv2.6
Note the usage of –no-setuptools option. I had error related to pip and setuptools that could not be installed.
So, now we need to install them manually, but before, let us activate the newly created virtualenv:
cd virtualenv2.6 source bin/activate
and now, let us download and install setuptools:
wget https://bootstrap.pypa.io/ez_setup.py -O - | python unzip setuptools-5.6.zip cd setuptools-5.6/ python setup.py install
and finally, let us install pip
that’s it we are ready to use python2.6
