I'm trying to install python's module aioserial (https://pypi.org/project/aioserial/) and I'm getting the following error:

This is not the first time pip has failed to install a package on the omega. This happens often and depending on the situation I usually switch between using opkg and pip to install python modules, but this time I don't have aioserial available in the openwrt package feed that has python packages to download.

I tried this on an omega running openwrt 18.06 and another one running openwrt 22.03 I even used a freshly flashed one running 18.06. I got the same results in all of my attempts. I would really appreciate some help,

Thanks!

Is there a way to get pip to be more verbose with the error message? That way we'll know what we're dealing with.

This are the full logs that I get after running pip3 install --verbose --verbose aioserial 2>&1 | tee installation.log:

I left it running for about 20 minutes but it seems like execution freezes at the last log.

Our next step should be to determine what's going on with the setuptools installation. Did the Omega2 maybe run out of space? You can check by running df -h

Here's sample output:

If the /dev/mtdblock6 partition is full or close to full that's the issue. You'll need to boot from external storage to have more storage space.

If not, then there's something wonky with pip's installation of setuptools. For both the Onion v0.3.4 firmware and openwrt 22.03, there's a python3-setuptools package that can be installed with opkg.
Try opkg update; opkg install python3-setuptools and then running your pip command again.

Also, when I tried to install python3-setuptools package, it appears that is already installed

Maybe pip just runs out of memory? Try making a swap file to extend the Omega's available memory: http://docs.onion.io/omega2-docs/extending-omega-memory.html

And then trying to use pip to install only setuptools

I can clearly see that I get OSError: [Errno 28] No space left on device which seems weird as I have plenty of memory left in the overlay storage:
