0.12: Requirements for pyscript not found: ['zmq==0.0.0']

[brianhanifin]

I just updated and pyscript fails to load with the following error.

2020-08-24 10:18:54 ERROR (MainThread) [homeassistant.config] Package pyscript setup failed. ->
  Integration pyscript Requirements for pyscript not found: ['zmq==0.0.0']. (See /config/integrations/pyscript.yaml:2). 

[brianhanifin]

Yikes! I just realized all of this is above that line.

FYI, I'm running Home Assistant Supervised.

  Warning: Couldn't find an acceptable libzmq on the system.
  
  If you expected pyzmq to link against an installed libzmq, please check to make sure:
  
      * You have a C compiler installed
      * A development version of Python is installed (including headers)
      * A development version of ZMQ >= 3.2 is installed (including headers)
      * If ZMQ is not in a default location, supply the argument --zmq=<path>
      * If you did recently install ZMQ to a default location,
        try rebuilding the ld cache with `sudo ldconfig`
        or specify zmq's location with `--zmq=/usr/local`
  
  You can skip all this detection/waiting nonsense if you know
  you want pyzmq to bundle libzmq as an extension by passing:
  
      `--zmq=bundled`
  
  I will now try to build libzmq as a Python extension

        * If you did recently install ZMQ to a default location,
          try rebuilding the ld cache with `sudo ldconfig`
          or specify zmq's location with `--zmq=/usr/local`
    
    You can skip all this detection/waiting nonsense if you know
    you want pyzmq to bundle libzmq as an extension by passing:
    
        `--zmq=bundled`
    
    I will now try to build libzmq as a Python extension
    unless you interrupt me (^C) in the next 10 seconds...

Oh no. Zmq is used as the message transport by Jupyter, so it's now needed by pyscript to provide the kernel interface to Jupyter. I'm not familiar with how it is bundled and installed, but I'm looking into it. It did install cleanly on my system, but obviously not on yours.

[dlashua]

@craigbarratt I just upgraded to 0.12 and am having the same issue. I run the Home Assistant Docker container. The issues seems to be that "g++" is not included in that image (?) so compiling zmq fails. I believe the "Home Assistant Supervised" installation method uses the same docker image. I think perhaps even regular "Hass.io" or whatever that is called these days uses it as well. So this will likely break for many users.

[brianhanifin]

That's alright. I'll downgrade to 0.11 for now. Let us know when we can test a beta fix.

[craigbarratt]

Yes, I didn't realize the dependency wouldn't install cleanly, since it's extensively used by Jupyter. I don't know enough about zmq, HASS and pip to know how to do it reliably.

Two questions:

• Do you have Jupyter installed (eg, pip install juptyer)? If not, can you install it, and then see if pyscript 0.12 installs cleanly.
• What is the output from pip list | egrep zmq

Also, I wonder if I should just delete the release until I figure it out, since it clearly is broken, and that creates a bad user experience. Any advice is welcome.

[craigbarratt]

I went ahead and deleted the release until we can figure out the right way to handle the zmq dependency.

[brianhanifin]

I have Jupyter Lite installed as a Supervisor Add-on.

At the "Supervisor" command line, pip does not appear to be installed. I did notice that python3 was installed at /usr/bin/python3 not /usr/local/bin/python3. So I ran the suggested command from the error message with the correct python3 path /usr/bin/python3 -m pip install --upgrade pip. Now running pip list | egrep zmq yields an empty result (running pip list by iteself does provide a list of packages though, just no zmq).

[brianhanifin]

After I installed pip I tried reinstalling the newer version. Now I get ModuleNotFoundError: No module named 'zmq'.

@brianhanifin and @dlashua - I just pushed an update 279c134 that eliminates the need for zmq altogether. Could you try installing the master version using HACS and seeing if it installs and runs cleanly? This version has Jupyter support (console, notebook and lab), and some bug fixes. Thanks.

[dlashua]

It installed for me without issue. Thanks!

[brianhanifin]

I just installed the master "version" from the HACS Reinstall menu. Pyscript is loading again.
