Install aip on Mac High Sierra

[EddieCz]

Hello, i tried to install aip on Mac following https://wiki.seeedstudio.com/ArduPy/#install-aip-with-macos 1) homebrew 2) python3 3) pip3 install ardupy-aip
I had to manually create dir .config, then install went smooth, but if i tried to run aip i got this error :

File “/usr/local/bin/aip”, line 8, in
sys.exit(main())
File “/usr/local/lib/python3.9/site-packages/aip/main.py”, line 52, in main
from aip.command import commands_dict, parse_command
File “/usr/local/lib/python3.9/site-packages/aip/command.py”, line 46, in
from aip.build import buildCommand
File “/usr/local/lib/python3.9/site-packages/aip/build.py”, line 34, in
from pip._internal.operations.prepare import (
ImportError: cannot import name ‘_download_http_url’ from ‘pip._internal.operations.prepare’ (/usr/local/lib/python3.9/site-packages/pip/_internal/operations/prepare.py)

Many thanks for any help.

seems like your pip3 path is not in your $PATH? you may try echo $PATH and see

[EddieCz]

Hi, many thanks, looks like, it really isnt there. But it didnt help,
my echo $PATH looks like:
/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/bin/python3:/Applications/VMware Fusion.app/Contents/Public

Error message :

Do you have a complicated python env? Seems like the script not wokring properly. Can you run pip3 install request request

[EddieCz]

Output :
ERROR: Could not find a version that satisfies the requirement request (from versions: none)

ERROR: No matching distribution found for request

WARNING: You are using pip version 20.2.3; however, version 20.3 is available.

You should consider upgrading via the ‘/Library/Frameworks/Python.framework/Versions/3.9/bin/python3.9 -m pip install --upgrade pip’ command.

[ansonhe97]

Please could you try the installtion in a python virtual env such as this: https://docs.python.org/3/tutorial/venv.html

[EddieCz]

Hi, many thanks, now it works. But after all this effort i found that Python libraries exist only for few components, but not for EC sensor which i need.

Anyone with a fix for the original error ( ‘_download_http_url’ from ‘pip._internal.operations.prepare’ ) under Catalina? Looking at the source code on GITHUB for ‘prepare’ the function is not present…

Tried both python.org and brew versions of Python and virtual environment.

[ansonhe97]

I’m also under macOS Catalina and works fine, can you show us the full error msg?

[Andyroo]

The command I am issuing is the aip help from terminal as a normal user and I get back:

update local board json...
http://files.seeedstudio.com/ardupy/package_new_seeeduino_ardupy_index.json
done!

This is with Python 3.8.6 installed from python.org and the local version installed with brew removed.
Pip3 reports version 20.3.3 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)

[ansonhe97]

seems like an error from pip version 20:

Can you check the solution here for virtual env:

Unable to install anything using pip after upgrade to 20.0

[Andyroo]

Tried a couple of things based on that link but aip still references the base pip in the /Library/Frameworks rather than the virtual env.

Next is to try zapping Python and pip off the machine but get the feeling that a supplier of dev tools that is relying on old versions of packages (without forking the code) will be frowned on and that’s before we start development

[Andyroo]

Well that did not work. Mac has:

• Python 2.7.16
• Python 3.8.6
• Pip 18.1 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)

BUT as part of the install I get:

ardupy-aip 0.8.1 requires pip>=20.1, but you’ll have pip 18.1 which is incompatible.

So upgrading pip to 20.1 with sudo -H python3 get-pip.py pip==20.1 gives a different error:

ModuleNotFoundError: No module named ‘requests’

but a quick sudo -H pip install requests gives me an aip command that does not error on the help!

So it looks like the process is:

1. Install Python 3 on the Mac from python.org
2. Download get-pip.py
   curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
3. Run that to install version 20.1
   sudo -H python3 get-pip.py pip==20.1
4. Add the ‘requests’ module using pip sudo -H pip install requests

This MAY work in a virtual env but I’m not testing that til 2021.

FORGET IT - the next thing I try dies with

FileNotFoundError: [Errno 2] No such file or directory: '/Users/andrew/.config/aip/modules’

Going to ask for working instructions from the devs.
