Making python 3.3 default python 3 interpreter instead of 3.2
Solution 1
You can custom your python3
alias. For this, you can modify your .bashrc
file by appending "alias python3='python3.3'
" at the end of it. This shell script can do it for you :
#!/bin/bash
cd ~
# Create the ~/.bashrc file if it does not exist
if [ ! -f ./.bashrc ]; then
touch .bashrc
chmod 755 .bashrc
echo "#!/bin/bash" >> .bashrc
fi
# Append the customed alias
echo " " >> .bashrc
echo "alias python3='python3.3'" >> .bashrc
echo " " >> .bashrc
# Reload settings in the .bashrc script
source .bashrc
Solution 2
You may run different python versions on the same system by setting up the appropriate environment variables. This would allow you to locally install a later version of Python than the synaptic package manager might offer. e.g. in a file (mysetup) have:
TK_LIBRARY=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TKPATH=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TCL_LIBRARY=/usr/lib
export TCL_LIBRARY TK_LIBRARY TKKPATH
export PYTHONPATH=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/lib-stdwin:/usr/lib/python2.7/lib-dynload:/usr/lib:.
and put them into your environment with . mysetup

So, to keep it simple. Ubuntu 12.10 has python 3.2 pre installed and it is linked to "python3". I downloaded python 3.3 and it's command is "python3.3". However, I downloaded pySide for python3 from synaptic. Using "from PySide.QtCore import *" fails on python3.3. BUT, when I ran just "python3" (aka 3.2) everything works fine. Synaptic just installed lib for python3.2 which is default for python3 in ubuntu. How can I force synaptic to install modules for python3.3?
Thanks

user1873947 over 11 yearsThanks. This will make installing modules from synaptic to python3.3 dir, yes?

user1873947 over 11 yearsWell, this indeed makes "python3" run "python3.3", but after installing python3 module from synaptic, it still installs only to python 3.2... There must be some magic with symlinks to 3.3 location.
