Installing Python 3 (from netlabs exp) does not work

[Lars]

I had nothing better to do so I attempted to install python 3 via ANPM.
I get this error:

python-pycurl-7.19.5.1-2.oc00.pentium4 benötigt python27.dll

However, I do have a file "python27.dll" in \usr\lib and I have no probs at all with the currently installed python 2.7.

I then tried:

yum install python3 and get this:

Code: [Select]

 Sie können versuchen mit --skip-broken das Problem zu umgehen.
 You could try running: rpm -Va --nofiles --nodigest
This gives me the impression that there is a conflict with the already installed python 2.7

Unfortunately I cannot catch all screen output of "yum install python3" but I also get this:

Code: [Select]

Fehler: Paket: yum-3.4.3-13.oc00.pentium4 (installed)
            Benötigt: python(abi) = 2.7
            Entfernen: python-2.7.6-25.oc00.pentium4 (installed)
                python(abi) = 2.7
            Überholt durch: python-unversioned-command-3.9.5-5.oc00.pentium4 (netlabs-exp)
                Nicht gefunden

However, attempting to install "python-unversioned-command-3.9.5-5.oc00.pentium4" again gets me to this error:

python-pycurl-7.19.5.1-2.oc00.pentium4 benötigt python27.dll

Needless to say, running with "--skip-broken" or "rpm -Va --nofiles --nodigest" does not make a difference.

What further confuses me is that I have "python" (and various related packages) installed but I now see that there also exists a "python2.7" in netlabs-exp with various related packages. So how would I be able to replace "python" with "python2.7" ?

 Hey Lars,

 I struggled with this too, and reported  here: https://github.com/bitwiseworks/python-os2/issues/6

 Long story short: you need to use 'yum update python'. This installs both the new python2 and python3. But it doesn't seem to work if you are using the pentium4 platform, only works with i686, at least not for me.

One problem is that yum itself uses Python.

[Dave Yeo]

IIRC, you need to update to the latest Python 2.7 to get the new python27.dll, reboot, then update Python (and yum) and to be safe, reboot.
Well written scripts should find the correct Python version, with python pointing at python.exe which is Python3 and python2.7 which points to python2.7.exe. Sometimes it helps to have %PYTHON% = python2.7.exe to run python2.
Anyways the reboots are important to replace the locked DLL.

Anyone know how to get python3 installed? Log attached is what I'm getting on two different AOS installs

This is part of anpm install

 Paul,

  The only way I was able to install python3 was by disabling all repositories in ANPM except netlabs-exp, closing ANPM, then on a command line typing 'yum update python' (no '3'). This updated both python 2 and added python3. YMMV.

Hi David,

Thanks for your explanation how to install Python 3. It was working here quite well.

Greetings, Mike

Thanks - this worked for me on the 1st machine I tried it on.

Cheers,
