I'm trying to install the MicroWebSrv2 https://github.com/jczic/MicroWebSrv2 after having tried successfully the first version
on a M5atom lite https://docs.m5stack.com/#/en/core/atom_lite

If anyone has done this before, I'd be glad for every hint. Here's what I have done so far:

I copied the file structure (Solution 3 in the instructions) and added the setup.py to the main,py

The web server starts, but runs into a traceback claiming missing MicroWebSrv2/mods/WebSockets.py which is there:

Code: Select all

Connection successful
('192.168.1.46', '255.255.255.0', '192.168.1.1', '192.168.1.1')
running on M5atom lite

   - Python pkg MicroWebSrv2 -
   -      version 2.0.6      -
   -     by JC`zic & HC2     -

Traceback (most recent call last):

MicroWebSrv2Exception: Cannot load module "WebSockets".

this is raised by this code in MicroWebSrv2/microWebSrv2.py:

Code: Select all

# ------------------------------------------------------------------------

@staticmethod
def LoadModule(modName) :
    if not isinstance(modName, str) or len(modName) == 0 :
        raise ValueError('"modName" must be a not empty string.')
    if modName in MicroWebSrv2._modules :
        raise MicroWebSrv2Exception('Module "%s" is already loaded.' % modName)
    try :
        modPath  = MicroWebSrv2.__module__.split('microWebSrv2')[0] \
                 + ('mods.%s' % modName)
        module   = getattr(__import__(modPath).mods, modName)
        modClass = getattr(module, modName)
        if type(modClass) is not type :
            raise Exception
        modInstance = modClass()
        MicroWebSrv2._modules[modName] = modInstance
        return modInstance
    except :
        raise MicroWebSrv2Exception('Cannot load module "%s".' % modName)

Here is the file structure on the M5atom lite, I had to copy

Code: Select all

XAsyncSockets.py

twice,.
Funny that it shows two times when made this listing with

Code: Select all

ampy --port /dev/ttyUSB0 ls -r

However, a first exeption concerning

Code: Select all

XAsyncSockets.py

has dissappeared since.

I had to compile it in as a frozen module to get it to work. Not sure that will address your exact issue. Sorry I can't help further, I didn't use it beyond a bit of exploring. Ended up going the asyncio route.
