Puppy Linux Discussion Forum

Hey there, my first question and first puppy!

I'm trying to install python3 to my laptop with bionicpup32.

I downloaded python3.x.x package through ppm, but after the installation, I can't find python3 executable.

What can be the problem? Maybe there's no 32-bit version of python3?

Type which python3 in terminal and it should tell you where the python3 executable is. Normally /usr/bin/python3 but that will probably be a symlink to an executable with python3xxx (some more numbers on the end). If the symlink is missing you can create it. There is a 32bit version and PPM should have told you if the installation was successful or not.

EDIT:- I just booted into a fresh BionicPup32 and installed python3-3.6.7-1 via PPM to test. The executable symlink for python3 is missing, but python3.6 is there in /usr/bin so just right click on that and select "Link" and name the created link as python3

Well, which python3 gives nothing..
And I searched in /usr/bin/ and there's no python3.8 there.

If I ```ls | grep py``` in /usr/lib gives only those: dh_python2, pydoc, pydoc3.8 pygettext2.7 pygettext3.8 python python2.7 etc.

No actual interpreter there.

I installed it via ppm, package python3.8_3.8.0-3, installation went successful as was said by ppm.

Ah OK, so you installed the later version of python3 in which case the executable will be /usr/bin/python3.8 so just create the python3 symlink as a link to that. If it is not there that is strange, maybe try uninstalling and install the 3.6 package instead.

It works!

Thank you!

Installed python3.6 from its package and it works fine.

Although this is really strange, that python3.8 comes with everything but the interpreter....

Should I report it somewhere?

Well I uninstalled the 3.6 and installed the 3.8_3.8.0-3 package instead and /usr/bin/python3.8 is there.
You can use which python3.8 or which python3.6 or whatever of course
Then in terminal with cd /usr/bin followed by ln -s python3.8 python3 to create the symlink or you can do it in ROX-Filer of course.

You could download the source, from, for example, https://www.python.org/ftp/python/3.9.5/
Python-3.9.5.tar.xz is about 18MB

First, backup the save file or save folder.
Load the devx sfs file.

Unzip the tar.xz file in, for example, /tmp/

cd /tmp/Python-3.9.5/
./configure
make
make altinstall

Or make install but that will overwrite the Python 2.7 that is already installed.

It does not make a symlink python3 to /usr/local/bin/python3.9 You can do that manually.
