Conda recipe is broken

Hopefully someone can have a look.

The first problem was that the conda-forge julia package was missing a dependency. I fixed that in conda-forge/staged-recipes#16113 and conda-forge/julia-feedstock#126

Now we are hitting another error in the test phase that I don't yet understand:

I built a local version without the tests and uploaded it to https://anaconda.org/izahn/sos-julia . When I try to run it I get this error:

Thanks for your report. I am working on vatlab/sos-notebook#328 which is caused by a newer version of jupyter_client. I will have a look at this once that issue is fixed.

[izahn]

OK great, thank you for the note! I tried one additional thing in case it helps later when you get back to this.

I noticed that the error above was about not finding packages, so I

1. made a symbolic link from ~/.jula to /home/conda/.jula
2. installed IJulia, Feather, DataFrames, and NamedArray from the julia command line.
3. restarted jupyter lab and created an sos julia kernel and tried print("Hello World").

Here is what I saw:

ok. I fixed sos-notebook, and installed julia and the Ijulia kernel, and sos-julia, it all seems to be working alright.

I will test the sos-notebook (async branch) a bit more and make a release, then I will release sos-notebook on conda-forge, and we will see if the sos-julia conda recipe will work correctly.
