I need to find a "simple" non-destructive way to install and update a separate version of Python for software development purposes on Centos 6.5.
I followed two tutorials:
The latter having worked for me fine once before but doesn't now with 3.4.* and seems not to install at all. I tried anaconda and had the same issue with pycharm not even being able to recognise Python. I was able to combine the two and install Python 3.4 manually as a shared library and had to manually install the numpy for Python 3.4. env but when I tried to install Scipy I get a number of errors ending with:
Command "/usr/local/bin/python3.4 -c "import setuptools, tokenize;__file__='/tmp/pi
ze, 'open', open)(__file__).read().rep
', '\n'), __file__, 'exec'))" install --record /tmp/pip-lpfletex-record/i
y-managed --compile" failed with error code 1 in /tmp/pip-build-058c4cky/sc
Which I am unsure as to it's meaning but suspect it may related to errors that I received when trying to setup the virtualenv as per the second link.
Any advice? - I also have to unfortunately do the same thing for windows but don't want to look at that until I get it sorted on Linux.
