Using pyenv with Orange Pi
Orange Pi Zero 2 is a great product which I use a lot for a side projects. It's pretty cheap, has a tiny size and also easy to setup and run. Those it's good alternative to cloud environments if you need some not very beefy server to run your experiments. I'm running a few web crawlers on Orange PI and very happy with that.
I use Armbian Debian as an OS for orange pi. It's pretty straightforward how to setup it:
- download the image compatible with your device
- flash it to reliable microSD card with Etcher
- Insert the microSD card into the memory slot of the Orange Pi Zero, connect an Ethernet cable and plug in a micro USB cable to power the board.
- Find new host on your local network and connect via ssh ssh root@192.168.1.144 with default password 1234
That simple
By default python 3.7.3 is installed on Armbian (on 2021-12-03). But my codebase uses a different versions of python, and if I'd not to mess up all the environment at the start I need to setup some python version management which allows to switch python versions based on project's need. I preffer to use
It's not to hard to install it, all the needed instructions are in its repo
First you need to install build dependencies
sudo apt-get update; sudo apt-get install make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
Then run installation via the following command, which I find very convenient (although you could clone repo and build it yourself)
curl https://pyenv.run | bash
Then you need to run a set of commands to setup your environment variables
sed -Ei -e '/^([^#]|$)/ {a \
export PYENV_ROOT="$HOME/.pyenv"
a \
export PATH="$PYENV_ROOT/bin:$PATH"
a \
' -e ':a' -e '$!{n;ba};}' ~/.profile
echo 'eval "$(pyenv init --path)"' >>~/.profile
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
Now you have pyenv installed and ready to use.
pyenv install 3.10.0
I tried it and got the following result (which you probably got too if reading it)
pyenv install 3.10.0

You can check the logs and though the reading it you will notice something like /tmp no space left on device what's pretty weird as there's a lot of space on newly spinned server.

You might notice that /tmp /dev/zram1 468M 752K 433M 1% /tmp isn't a big enough , but pyenv is used it to unpack and operate during installation. So you need to fix it somehow. There's a few solutions, including increasing /tmp size, but the simplest one is to add TMPDIR environment variable which allows pyenv to use all the disk space on device where you pointed it. Run in terminal or add it to .bashrc if you want to make it permanent (as pip will also use TMPDIR).
export TMPDDIR=/var/tmp
This will fix the problem and a next pyenv run will be completed succefully.
PS / You might get the following error
pyenv install -v 3.10.0
python-build: TMPDIR=/var/tmp is set to a non-accessible location
That's the result of running systemctl mask tmp.mount which is another option to fix /tmp space issue. To fix it you need to remount sudo mount -o remount,rw /
