struggle tweets to install python 3.10.2 with pyenv on Ubuntu 20.04 (WSL)

If you want to watch me struggle, continue below. Otherwise just go here: https://computingforgeeks.com/how-to-install-python-on-ubuntu-linux-system/

I just bought a new laptop and figured, setting up my WSL Ubuntu environment should be pretty straightforward right? All I need to do is git clone a few repos and setup my $PATH.

I was very wrong.

I’m not an expert in setting up Linux environments and it just so happened that Stackoverflow was going through some things (https://twitter.com/StackStatus/status/1502788125285879817).

Anyway, some of the things I needed to get my pyenv v2.2.4 to even install python v3.10.2

At this point I’ve already apt install the following:

gcc
make
build-essential
gcc
make
build-essential


gcc
make
build-essential

but I’m still getting the following error:

okay, what is zlib? https://packages.ubuntu.com/source/focal/zlib

Not too helpful, as there are a bunch of different packages here that I can install, but which one?

The internet seems to say zlib1g-dev.

So I suppose I’ll need to get the dev versions of all these C library packages:

zlib1g-dev
libbz2-dev
libsqlite3-dev
libgdbm-dev
libssl-dev
libncurses5-dev
libreadline-dev
liblzma-dev
zlib1g-dev
libbz2-dev
libsqlite3-dev
libgdbm-dev
libssl-dev
libncurses5-dev
libreadline-dev
liblzma-dev


zlib1g-dev
libbz2-dev
libsqlite3-dev
libgdbm-dev
libssl-dev
libncurses5-dev
libreadline-dev
liblzma-dev

Enter fullscreen mode Exit fullscreen mode

Anyway, since I know nothing and am just meandering through this on my own even though I can copy paste the list of dependencies someone else has posted on the internet, I decide to only install zlib1g-dev since the other ones are required for optional modules (which I’ll probably need later and regret not installing now).

Okay so what happens when I try to pyenv install 3.10.2 now?

Okay that seems like a more positive step. The only error that I see now is that ssl extensions was not compiled. Seems important. Let’s install libssl-dev
