trouble when installing

[parmentelat]

this is on macos
recently I got my python/jupyter install very mixed up and decided to restart from scratch

despite of that - or maybe because of that - what I'm seeing now is this

$ python -m metakernel_bash install
Installed kernelspec python3 in /usr/local/share/jupyter/kernels/python3
$ cat /usr/local/share/jupyter/kernels/python3/kernel.json
{
 "argv": [
  "/usr/local/opt/python/bin/python3.7",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3",
 "language": "python"
}

I can't seem to get metakernel_bash to appear in

$ jupyter kernelspec list
Available kernels:
  bash       /Users/tparment/Library/Jupyter/kernels/bash
  python3    /usr/local/share/jupyter/kernels/python3

where bash is the kernel that somes from the alternative bash_kernel

a couple weeks back I had had no problem having the 3 kernels coexisting in my jupyter environment

thanks for any hint that would let me troubleshoot that

Hi @parmentelat, had you installed metakernel_bash from a git checkout? If so, what command did you use to install it, and what does git describe give in that checkout?

[parmentelat]

hey @blink1073

no I did the initial installation with plain pip

$ pip install metakernel-bash
<snip>
$ pip freeze | grep metakernel
metakernel==0.23.0
metakernel-bash==0.11.3

Oh wow, I didn't realize we had released metakernel_bash. The last release was 4 years ago. I'm going to promote it to its own repo and give it a proper release.

[Steven Silvester]

The plot thickens. I forgot I had created calysto_bash as a separate repo already. Please try with pip install calysto_bash.

[parmentelat]

this works better:

$ pip install calysto_bash
Collecting calysto_bash
<snip>
Successfully installed calysto-bash-0.2.1
$ jupyter kernelspec list
Available kernels:
  bash            /Users/tparment/Library/Jupyter/kernels/bash
  calysto_bash    /usr/local/share/jupyter/kernels/calysto_bash
  python3         /usr/local/share/jupyter/kernels/python3

so; I guess I'm all good - provided that calysto_bash is a new name for the same thing ?

---

it's funny though because the way I did it earlier with metakernel_bash is working in another environment - at least it was working when I rebuilt a docker image based on top of jupyter/minimal-notebook something like 2 days ago
but, no big deal in any case ..

---

anyways, thanks for your help :)

[Steven Silvester]

Yeah I had the same weird issue with metakernel_bash installing as a python3 kernel as well. calysto_bash will henceforth be the supported version 😉. cf #186.
Note there is still a separate bash_kernel that does not include magics.

Cheers!
