Install

[Cronbo]

Trying to get this installed on my raspberry pi 4 but running into the following error after running this step in your instructions. Any ideas?

Command: pip install git+https://github.com/plottertools/taxi#egg=tax

Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

@Cronbo it looks like you need this too:

sudo apt-get install python3-dev

Note that your command should read as follows (but this is likely not the issue):

pip install git+https://github.com/plottertools/taxi#egg=taxi

(missing i at the end)

Also, the install procedure should be considerably simpler with vpype 1.7.0, if you don't require vpype viewer (taxi doesn't need it). I have yet to update the instructions.

[Cronbo]

I will try your suggestions in a bit. And yes, the “i” in taxi was missing when I copied and pasted the command to this message. When I ran it (multiple times) it was properly spelled. I’ll report back if I have any further issues. Thanks for the help!

[Cronbo]

Hello, I tried your suggestion and ran “ sudo pip install python3-dev ” but then got the following error:

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly. Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple ERROR: Could not find a version that satisfies the requirement python3-dev (from versions: none) ERROR: No matching distribution found for python3-dev

Any other tips? Thanks!

[abey79]

Sorry, the correct command is sudo apt-get install python3-dev

[Cronbo]

Ok, I ran the command and got this:

Also tried installing again using the latest instructions and ran into the following issues:

1. The $ sign at the beginning of each command listed should not be included as it generates an error, when this website’s “copy/clipboard” icon is used to copy the command
2. I get this error message after i run the command without the $

pi@raspberrypi:~ $ sudo apt-get install python3.9 python3-dev python3-shapely python3-pil python3-numpy python3-scipy python3-serial python3-pygame libsdl2-dev Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package python3.9 E: Couldn't find any package by glob 'python3.9' E: Couldn't find any package by regex 'python3.9'

[abey79]

Yeah I didn't realise that this would interfere with the copy/paste feature. The $ is there to signify that the command should be entered in a terminal.

This is probably because you are on raspbian stable (as opposed to testing). Apparently 3.9 is not available there. You may try by replacing with python3.7, it should work and should be supported.

Will it still work?

Try installing the axidraw python api manually, as per EMSL's instructions.
