AttributeError: module 'PyCmdMessenger' has no attribute 'ArduinoBoard'

Hi,

Thanks for creating PyCmdMessenger, it's been working great for me and really makes my product possible.

I've just setup a new Ubuntu VM running inside of VMware Workstation 15 Player. I installed python 3.6.9 I installed tkinter, pip3, and then PyCmdMessenger. When I run my program I get AttributeError: module 'PyCmdMessenger' has no attribute 'ArduinoBoard'. I'm relatively new to Linux and python programming, so it's likely I'm doing something that's obviously wrong to others.

dmurphy@ubuntu~$ python3 -V
Python 3.6.9
dmurphy@ubuntu~$ sudo apt install python3-pip
dmurphy@ubuntu~$ sudo apt-get install python3-tk
dmurphy@ubuntu~$ pip3 install PyCmdMessenger
dmurphy@ubuntu~$ find / -name PyCmdMessenger 2>/dev/null
/home/dmurphy/.local/lib/python3.6/site-packages/PyCmdMessenger
dmurphy@ubuntu~/dev/python/PasswordPump$ python3 PassPumpGUI_v0_7.py
/dev/ttyS0: ttyS0
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python3.6/tkinter/init.py", line 1705, in call

arduino = PyCmdMessenger.ArduinoBoard(port, baud_rate=115200, timeout=5.0, settle_time=2.0, enable_dtr=False,
AttributeError: module 'PyCmdMessenger' has no attribute 'ArduinoBoard'

Also:
dmurphy@ubuntu~$ find / -name site-packages 2>/dev/null
/snap/python38/22/lib/python3.8/site-packages
/home/dmurphy/.local/lib/python3.6/site-packages

I read another similar thread here and it seemed to indicate that I need to install PyCmdMessenger under /snap/python38/22/lib/python3.8/site-packages, however when I try to copy the PyCmdMessenger directory to /snap/python38/22/lib/python3.8/site-packages, it fails and claims that it's a read only directory. I really have no idea if it's the right fix.

I also tried copying PyCmdMessenger-0.2.4.dist-info and PyCmdMessenger from /home/dmurphy/.local/lib/python3.6/site-packages to /usr/local/lib/python3.6/dist-packages, and that didn't work.

Thanks for the help and the tool!!
