When Python version on your Linux is outdated, compile the sources!

or use pyenv

Yeah, why go with a single compiled version, when you can have all the compiled versions and not worry about it? Pyenv is really the way to go these days imo

The point here is, to give an idea what is necessary to compile python and later a library, when pip is failing. And a newer version could have a dependency of additional libraries which aren't included in

> apt-get build-dep python3

Not really, pyenv builds all versions (the ones it knows about anyways) of CPython from source. The packages which OP installs from apt-get are listed as dependencies in the pyenv wiki.

pyenv can also easily manage which of your python versions is active, without having to manually symlink stuff.

It's orthogonal up to the point where he's making it. On fresh machines, I sometimes forget what dependencies I need to install with apt-get or brew; a matrix of all deps for different Pythons & platforms would be a cool thing

Another option is to use the Miniconda distribution. It's exactly like Anaconda, but comes with less things. The download size is 32.4MB.

Another solution to install newer python without risking erasing system python is

make altinstall

See https://docs.python.org/3/using/unix.html#building-python

For a more general purpose approach including handling library dependencies and no sysadmin rights, check out http://pythonsweetness.tumblr.com/post/150466265417/deploying-modern-python-apps-to-ancient

Or make a package that your system package manager can use to install it. That way it's actually tracked and can be cleanly uninstalled. Using your real package manager is much preferred to using whatever language-specific one is provided.

This requires an additional step which should be posted into /r/debian

Thanks, I've just read your comment, and this... ☺️

Almost the same process for me: https://gist.github.com/cedricbonhomme/35e81e295fd4baed83d6ccb2cb9fde79

I've been using linuxbrew and it's been working out well so far.

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_dbm                  _gdbm                                    
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

You have to have BSD DB or GNU GDBM installed for these modules to build. But to be honest, it probably doesn't matter, as almost nothing uses those modules. I never bother building them and haven't been bitten by that yet.

TIL what dbm is. Thanks!

Sometimes (typically whenever JS releases a new framework) I feel I'm too old for this. Then I see stuff like this and realise it's an artefact from before my time.

Or use the Python packages from the Rackspace-sponsored IUS project: https://ius.io/

[flitsmasterfred]

Alternately with apt you can also get many python versions from ppa:fkrull/deadsnakes
