Subject	Too many python installations. Should i remove them all and install the latest?
Message-ID	<063fc449-5582-4a84-9eea-35e04344dbe0@googlegroups.com>

I'am using CentOS v6.4 on my VPS and hence 'yum' install manager and i just tried:

Code:
root@nikos [~]# which python
/usr/bin/python
root@nikos [~]# which python3
/root/.local/lib/python2.7/bin/python3
root@nikos [~]# which python3.3
/root/.local/lib/python2.7/bin/python3.3
root@nikos [~]#

Why so many pythons in my system.
Now in the case of my Python3 installation, it looks like i have two parallel installations of Python3, but i don't. One is almost certainly a symlink to the other and not an actual installation.

I'm thinking of:

yum remove python
yum remove python3
yum remove python3.3

and 

yum install python3.3.2 from scratch.

I'm sceptic about uninstalling python 2.x though. Seems to me as a bad idea because most of the core system utilities are written in Python 2.6+. Yum, for example, is a collection of Python 2.6 programs. If i actually do "yum remove python" i will see most of my core system get listed in the uninstall dependency list -- which is a Bad Thing.

But then again i dont like the idea of having too many Python into my system.
What is you opinion?

Check if python3 and python3.3 aren't the same. Run them and look at the
"intro" lines.

So it looks like you have two Python installations, one for Python 2
and one for Python 3.  Why is that too many?

Well is it a symlink?

What a fantastic way to completely break your os!  Python 2 is is a deep
dependency of CentOS.  You cannot remove it.  Python3 and 3.3 can be
removed of course.

Oh, I see.  The python3 and python3.3 are probably the same binary, though.

In any case, since Python 2.7 and Python 3 are both installed under
/root/.local, it looks like you didn't install them using yum in the
first place.  You probably installed them from source.  If that's the
case, you can probably just rm -rf the python2.7 folder from each of
the /root/.local subfolders that has it.

I don't know, is that where you were keeping the data?

The website still appears to be working, as best I can tell from this
computer.  I've never actually been able to view it from here, because
I get a UnicodeDecodeError at this line:

host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]

But at least I'm still seeing that error, so the server is still
responding to requests.

Everything seem to be workign as expected, my webiste and the other 10 client websites just chhecked.

luckily i keep my stuff at /homw/nikos so there are untouched.
i hope i havent deleted anything though system need form /root/.local but i guess this is where root's user personal stuff and instalation of python from source where. i ddidnt know if it has soemhtign else.

Couldn't you check ten websites which are your responsibility, instead of
asking this list?

Good.

No. Wait. Why are you uninstalling python 2.6? Because you have too many
python installations?

If you're on a production server with client data, should you really have a
root shell?

Explained below, underneath each pertinent info you provided.

First, let's discuss Python 2.6:

This is the version of that CentOS 6 is using. It is Python 2.6 as
shown in the next paragraph. This version is essential to CentOS 6.
This cannot be changed or upgraded without so much work that no sane
person on the planet would bother. Stop worrying about it.

See above.

Apart from the bizarre trailing '*' characters which for which I have
no sane explanation, all of the above is standard for Python 2.6 which
is essential for Centos 6. Stop worrying about it.

Now let's talk about yum:

Your yum setup does not find python3 or python3.3 packages.
So you could not have used yum to install it.
Therefore, you cannot use yum to remove it.
And, you cannot use yum to install it.

Now let's talk about Python 2.7:

There's a python2.7 directory there under /root/.local. Maybe you
installed python2.7 from source using some kind of 'make install'
command (ie not using yum)? If so, and you wish to remove it, there
will probably be another 'make' command to remove it, which must be
run from the same directory that you ran 'make install'. Try 'make
help' in that directory. Maybe someone else can explain why there is a
python3 command under that directory, because I can't.

Now let's talk about Python 3:

There's a python3 directory there under /opt. Maybe you installed
python3 from source using some kind of 'make install' command (ie not
using yum)? If so, and you wish to remove it, there will probably be
another 'make' command to remove it, which must be run from the same

When trying something you don't fully understand, first experiment
somewhere you don't care if bad things happen.

No. Different versions do different things. Don't install or remove
them until you understand the different things they do.

cant remove it.

Why you say i cant just yum install python3.3.2

that way it would be installed correcttly automaticall by yum manager
and if later i want to remove ot to install 3.3.3 or a later version i
would have to do yum remove python3.3.2

but yum cant seem to find any python packages to install.

Still i feel my system is a bit messed p and i just want to leave the
2.6 installed and remove all the rest python and then yum install
the_latest_one.

It's not half as messed up as... uhh, scratch that. It's not half as
messed up as the testbox I have at work. (Yeah, we'll go with that.
More courteous.) You do not have a problem there that is worth
breaking your system for.

The Makefile would be located in the source directory where you built
Python, not in the installation directory.  But in any case, I don't
think the Python Makefile includes an uninstall option.  If you want
to uninstall Python that was built from source, you need to remove the
files by hand.

> Why you say i cant just yum install python3.3.2

Because CentOS 6 evidently does not provide a package for any version
of Python other than 2.6.  If you want to install another version, you
will need to do it from source.

Do you think that i should have my VPS copmany to install ubuntu for me and use apt-get install python3 ?

I think ubuntu is friendlier.

Probably friendlier than humans will be, considering that Ubuntu
doesn't complain about careless use of Google Groups.

Why not try making your own administrative decisions, rather than
expecting other people to validate you? Are you that short on
confidence that you need someone to say "Yes yes, you're doing the
right thing" and pat you on the back?

I believe that indicates that his 'ls' is aliased to 'ls --classify',
which puts * after executables (and / after directories, and @ after
symlinks, also a few others). Not a problem.
