uPyEasy unix port on Raspberry Pi

[AndrewJ]

Encouraged by @Edu.Uy's success, I decided to give it a go myself, as I have a Raspi3 available (running my Home Assistant system) and it should give me a way of combining easy development of the OpenHAB MQTT protocol with available "live" data.

All has gone well up to the point of starting upyeasy (using ./micropython -m upyeasy as before). It creates the file structure ok, but then hits a series of errors which look to me like a problem with the db. My log is below...

Code: Select all

It looks like the database has already created the tables (on earlier attempts when I was hitting other errors with missing modules). How to get back to a clean start?

Hello,
there you are already further than me.
I get:


root @ pi160:/opt/micropython/ports/unix # ./micropython -m upyeasy
Traceback (most recent call last):
   File "upyeasy / __ init__.py", line 14, in <module>
   File "upyeasy / core.py", line 30, in <module>
ImportError: no module named 'os'

Hello, @micropet,
I got that error, and a number of others, at an earlier stage before I sent my message. I was advised by another forum member, @Edu.Uy, of the solution, which is to exit from micropython/upyeasy back to ~/micropython/ports/linux $, and type

Code: Select all

./micropython -m upip install micropython-<module_name>

(You may get it saying upip is not found when you do it the first time, in which case apt-get install upip,)

Then try again

Code: Select all

./micropython -m upyeasy

and you may get a different error.

I had a series of about 8-10 missing modules, it's a matter of working through them until it has all it needs.
One which was a bit peculiar was a module named "re" (regular expression). I tried the same approach as above, and it appeared to install, but micropython still complained that the module was not found. Edu advised using re-pcre instead, and that worked.

Hope this works for you!
And, if you don't get the error I'm having, please let me know how to avoid it!!

Many Thanks. Again a little further.
Lisa makes it very difficult for us.

I'm stuck with onewire:


  ./micropython -m upip install micropython-onewire
Installing to: /root/.micropython/lib/
Warning: pypi.python.org SSL certificate is not validated
Error installing 'micropython-onewire': package not found, packages may be partially installed

For _onewire, please refer to this message which has a zip file attached...
