installing python 3 on ubuntu 10.4

casperdaghost · 03-02-2012, 01:18 AM

so i wanted to run a script that requires python 3.

i am running ubuntu 10.4

so i install it via synaptic

but when i check the version --

Code:

casper@casper-SX280:~/public_html$ python -V
Python 2.6.6
casper@casper-SX280:~/public_html$

so i manually download Python-3.2.2.tar.bz2 and copy it to the desktop.

untar the file using:
tar -xvjpf Python-3.2.2.tar.bz2

type in :
./configue

then type:
make

then type:

sudo make install

i dont see any errors - but
again when i check the version --

Code:

casper@casper-SX280:~/public_html$ python -V
Python 2.6.6
casper@casper-SX280:~/public_html$

do i have to uninstall python 2 to install version 3?

The command to run python 3 will be something along the lines of python3.2, not just python.
Run

Code:

ls /usr/bin/python3*

to see the version you have.

Code:

casper@casper-SX280:~/public_html$ ls -tlr /usr/bin/python3*
-rwxr-xr-x 1 root root 2547004 2011-12-09 16:50 /usr/bin/python3.1
lrwxrwxrwx 1 root root       9 2012-03-02 00:39 /usr/bin/python3 -> python3.1
casper@casper-SX280:~/public_html$

OK so I guess when i run my scripts i will just use the invocation:
#!/usr/bin/python3

thanks - that makes sense
