read_minimed_next24.py: No module named 'hid' error

[jrussell88]

I'm running Ubuntu 17.04; I installed hidapi, but read_minimed_next24 is failing with the error:
ImportError: No module named 'hid'

/git$ python3 -m decoding-contour-next-link.read_minimed_next24
Traceback (most recent call last):
File "/media/john/Home/john/git/decoding-contour-next-link/read_minimed_next24.py", line 8, in
import hid # pip install hidapi - Platform independant
ImportError: No module named 'hid'
During handling of the above exception, another exception occurred:

File "/media/john/Home/john/git/decoding-contour-next-link/read_minimed_next24.py", line 9, in
except WindowsError:

Can anyone suggest what might be causing this?

# pip3 install hidapi

[jrussell88]

I reinstalled the dependencies for pip3;

$ sudo -H pip3 install cython
$ sudo -H pip3 install hidapi
$ sudo -H pip3 install requests astm PyCrypto crc16 python-dateutil
$ sudo -H pip3 install python-lzo

Then:

/git$ pip3 install -r requirements.txt

As I was still getting file errors:

/git$ python3 -m decoding-contour-next-link.read_minimed_next24
Traceback (most recent call last):
File "/usr/lib/python3.5/runpy.py", line 193, in _run_module_as_main

I ran the commands as root:

/git$ sudo python -m decoding-contour-next-link.read_minimed_next24
/git$ sudo python3 -m decoding-contour-next-link.read_minimed_next24

which worked.

@jrussell88 I am currently fighting this problem with opening the HID as ordinary user. I am fixing the permissions with UDev rules, which looks like they work. I am out of my depth here, since on some PCs I still get errors when opening the device, even though the permissions seems to be allowing me.
