MbedCLI requirements.txt throws error for hidapi

Mbed CLI
1

I’ve been trying to utilize mbedcli tools for a project. However everytime I use the command
mbed test
The command runs but I get the following warning:

The Mbed OS tools in this program require the following Python modules: hidapi, cmsis_pack_manager, psutil, cryptography, click, cbor
       You can install all missing modules by running "pip install -r requirements.txt" in "${Workspace-folder}/mbed-os"
       On Mac you might have to install packages as your user by adding the "--user" flag

Doing exactly as it asks, I run:

pip3.7 install -r requirements.txt --user

Resulting in:

error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Could not build wheels for hidapi, which is required to install pyproject.toml-based projects

Any assistance on this would be greatly appreciated.

Hi,

I could reproduce the error on macOS 14.5, python 3.12.3.

To fix this, I installed the latest hidapi module as below with venv.

$ python3 -m venv my_venv
$ source ./my_venv/bin/activate
$ pip3 install --upgrade pip

# edit the requirements.txt to remove restricted version (remove "<0.8.0")
-hidapi>=0.7.99,<0.8.0;platform_system!="Linux"
+hidapi>=0.7.99;platform_system!="Linux"

$ pip3 install -r requirements.txt
