Hi,
I wanted to install python, numpy and matplotlib on Linux Ubuntu.
I installed python with the following commands
./configure --enable-unicode=ucs4
make
make install
and then I installed numpy running
python setup.py install
Finally I came to matplotlib, that for the installation requires the
commands
python setup.py build
python setup.py install
but when I run the first (python setup.py build) I got the following
output that I copied partially below. What am I doing wrong? Can anyone
help?
I had previously another version of python located in usr/bin while the
current is in usr/local/bin. I guess I could remove the previous by the
deleting the relative folder and now if I run the command 'which
python' it actually says 'usr/local/bin/python' so I hope I done it
correctly. If not, how can I uninstall any previous version of python?
Do you think that somehow the error I get is caused by an unclean
removal of that previous version?
Thanks and regards
Francesco
