Cannot build (No module named 'cStringIO') #24

Closed desertspider closed 5 years ago

desertspider commented 5 years ago

Hi,

Since an autoupdate of something within PlatformIO, i can no longer build ESP32 Command Station. No matter what version.

The building stops with this error; ModuleNotFoundError: No module named 'cStringIO':

Downgrading python, c++, platformio or platformio core does not solve the issue.

atanisoft commented 5 years ago

What version are you using and which branch?

desertspider commented 5 years ago

I tried 1.2.3, latest stable (1.3.0) and latest Dev. All same problem.

Maybe this has something to do with it?

1.9.0 (2019-10-11) Python 3 has the highest priority over the Python 2 Use Python 3.7 as a default installer for Windows

atanisoft commented 5 years ago

Ok that would be it, python 3 removed cStringIO. I'll need to find a solution of some sort for it.

In the meantime, it may be easier to uninstall PIO, install python 2.7 (configure it as default in system path), reinstall PIO and hopefully it will use the 2.7 version. This could be a temp solution until I update the script to support both 2.x and 3.x python versions

atanisoft commented 5 years ago

This should now be working .... The latest PIO VSCode update has moved up to Python3 by default as you noted and required a bit of rework on the resource embedding script as Python3 has removed cStringIO as a standalone module and instead moved it into the io.StringIO package but this really shouldn't be used for binary data which instead should use io.BytesIO which has also been incorporated in the above commits.

Test builds have completed from master and also on the development branch. I do not guarantee that the latest master code is 100% stable as I ran into a few issues which have been resolved more recently on the development branch only. I'm working on some remaining issues before merging development down to master for v1.5.0 release, but you should be able to use the development branch in the meantime with it being mostly stable.

Thanks for the quick update. Flashing 1.5 without a problem. Only when starting the ESP32, i get this; Not sure if i should make a new issue. Bootloop:

@desertspider Start with erase flash from PIO and reupload the code, it looks like there is a corruption in the SPIFFS partition that is not being handled correctly. If that fails please decode the backtrace line using this decoder with a commandline similar to:

decoder.py -p ESP32 -e .pio\build\esp32\firmware.elf stack.txt -t $HOMEDRIVE$HOMEPATH\.platformio\packages\toolchain-xtensa32

with the backtrace in stack.txt

desertspider commented 5 years ago

Erase flash did fix it.

On an side note. The reason i re-flashed the latest version was because i didn't get 1.3 to work. I did manage to get the same shield to work with dcc++ on a mega. Problem is, ESP32CommandStation turns the track off when i send a command to the train. Tried with 2 trains. Both has a different decoder brand. How can i debug this?

Great, I'll setup a v1.2.3 build and "upgrade" to the v1.5 version and see what is causing it to go awry.

Sounds like the CS is crashing and restarting. Check the console output for the cause, it should have a backtrace like you posted above and you should be able to decode it using the py file above. Open a new issue to track that failure and include the config modules that you have enabled etc. I'll take a look at it more closely and see what might be causing it.
