Your error message indicates that the rust compiler is missing.

Install it with: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and try again?

[joeythecat4]

okay i will give that try now thanks

if neeed more let me know

[martinbrose]

You might need to restart your shell though. Have you logged out and in?

Or you might just need to add it to your PATH variable. The rust compiler should be in ~/.cargo/bin

[martinbrose]

If that doesn't help, then maybe try to install docker-compose this way: https://dev.to/elalemanyo/how-to-install-docker-and-docker-compose-on-raspberry-pi-1mo

You need to have some development libraries installed. As described in the link above.

[joeythecat4]

i get to 'sudo pip3 install docker-compose' and i get this

=============================DEBUG ASSISTANCE=============================

error: can't find Rust compiler

If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

To update pip, run:

  pip install --upgrade pip

and then retry package installation.

If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

This package requires Rust >=1.41.0.

so i don't what wrong

[martinbrose]

Right, in that case you need the rust compiler for all users. I think you might have installed it only for the user.

Best to deinstall the rust compiler for your user with: rustup self uninstall

And then install it with: sudo apt install rustc

That way it should be available when you do: sudo pip3 install docker-compose

[martinbrose]

Hang on, I think you can also just install docker-compose via apt: sudo apt install docker-compose

Maybe just try that.

[joeythecat4]

well at the moment im at Building wheel for cryptography (PEP 517) ... /

[joeythecat4]

okay this is what i get now i think we getting close and thank for your help so far

[martinbrose]

Great, looks like you breezed past your initial problem.

Now you only seem to need additional packages, like the docker sdk.

However, I haven't had these many problems when following the install instructions. Which Python version are you using? python3 --version

[joeythecat4]

python3 --version Python 3.10.0

python --version Python 3.7.3

[joeythecat4]

and what do you mean by docker sdk

[martinbrose]

If you're using Python 3.10 then your current problem is something else. You are too cutting edge with your version. They changed the collections API from collections.Mapping to be collections.abc.Mapping. Starting with Python 3.10. Hence you get the error: The error was: cannot import name 'Mapping' from 'collections'

I think the easiest for you is to just do the install steps within a virtual python environment, for example within the internet-pi folder: python3 -m virtualenv --python=[path to your python 3.7.3 bin] ansible and then activate that virtual environment with source ./ansible/bin/activate

Start with the pip3 install ansible step and work your way through.

[joeythecat4]

okay i will give it a try

[martinbrose]

Or try to upgrade your python 3.10 to a more recent version. Some people report that this problem doesn't exist with 3.10.2.

[joeythecat4]

okay i will give that a try becouse i just run python3 -m virtualenv --python=[/usr/lib/python3.7] ansible /usr/local/bin/python3: No module named virtualenv

but it was a pain to get python 3.10 on and working

[martinbrose]

Tbh, it's usually not worth the pain to be on the latest version. I think 3.8 or 3.9 should be absolutely fine for most use cases.

And in case you want to go down the line of the virtualenv in the future, you would need to remove the brackets around the python: python3 -m virtualenv --python=/usr/lib/python3.7 ansible Also, I would think it should be in /usr/bin and not in /usr/lib.

Good luck and have fun!

[joeythecat4]

i got python -V Python 3.8.12 installed but still get the same error as before and then i try virtualenv i get

python -m virtualenv --python=/usr/bin/python3.8 ansible /usr/local/bin/python3.8: No module named virtualenv

[martinbrose]

Pip3 install virtualenv

but before you go down that route make sure you understand what virtualenv is: https://docs.python-guide.org/dev/virtualenvs/

[joeythecat4]

okay but i just tryed agen and got this error and it looks difrent

and i just try to install virtualenv Pip3 install virtualenv bash: Pip3: command not found

[martinbrose]

Right, think my advice with virtualenv is not correct. Ansible will connect to your local host / host and probably use the system installed Python anyway.

And your problem is still your Python 3.10 install with it’s breaking change in the collections package. (See the collections.abc comment above) Probably best to use stackoverflow from here and search for a solution or you just need to wait until this has been addressed by Python updates. Your problem is with your system environment and not an issue with internet-pi.

The only two options I see as feasible for your level of Python knowledge is:

• Upgrade to 3.10.2 and see if that fixes it; or
• Downgrade your system wide Python install to 3.9

[martinbrose]

Or just follow what the error message tells you: install docker with pip install docker on your host 192.168.1.133 manually and see if that helped.

[joeythecat4]

well i already have docker install and running this second and im looking to change my Python3 becouse when i try sudo update-alternatives --config python3 update-alternatives: error: no alternatives for python3

bur for

sudo update-alternatives --config python There are 4 choices for the alternative python (providing /usr/bin/python).

Selection Path Priority Status

0 /usr/local/bin/python3.10 2 auto mode

• 1 /usr/bin/python3 1 manual mode 2 /usr/bin/python3.10 1 manual mode 3 /usr/bin/python3.8 1 manual mode 4 /usr/local/bin/python3.10 2 manual mode

Press to keep the current choice[*], or type selection number:

[martinbrose]

You mentioned above that you have installed python 3.8 already. I assume that you’re talking about your host 192.168.1.133?

As a work around you could just link your Python3 in /usr/bin to 3.8.

sudo rm /usr/bin/python3 and then sudo ln -s /usr/local/bin/python3.8 /usr/bin/python3

Try the internet-pi install then.

After successful doing this, change it back to 3.10, so you don’t break any other installs?

[joeythecat4]

i only put 3.10 for this and this is the new error after doing both commands

[martinbrose]

Well, I recommended the work around so you would use Python 3.8 instead of 3.10.

Just relink /use/bin/python3 to /usr/bin/python3.10 and google your error message.

Take it from there. Because at the moment your problem is using a Python version that is too new and therefore introducing some additional problems. It’s always the risk of being too fast on recent Python versions, because you will have some packages breaking due to hard API changes at major releases. You most likely would be all good with Python 3.8 or 3.9.

[martinbrose]

Very weird, I tested the install on a Debian 10 virtual machine with only Python 3.10.0 and I had absolutely no problem.

However, there might be another more simple way to help you out. In your inventory.ini, put the following behind your host declaration for 192.168.1.133: ansible_python_interpreter=/usr/bin/python3.7 For example, this line would look now like: 192.168.1.133 ansible_user=pi ansible_python_interpreter=/usr/bin/python3.7

Or if you replaced your Python 3.7 with 3.8 now, then this should be ansible_python_interpreter=/usr/bin/python3.8

I think that theoretically should avoid that ansible is using python3.10 on the host machine.

[joeythecat4]

i just try to relink 3.10 but sudo ln -s /usr/local/bin/python3.10 /usr/bin/python3 ln: failed to create symbolic link '/usr/bin/python3': File exists

and then i try to run that command sudo ln -s /usr/local/bin/python3.8 /usr/bin/python3 ln: failed to create symbolic link '/usr/bin/python3': File exists

and i run ansible_python_interpreter=/usr/bin/python3.8 or ansible_user=pi ansible_python_interpreter=/usr/bin/python3.7 or ansible_python_interpreter=/usr/bin/python3.7
