B2 not loading because of a missing "midas" -> "b2" rename

[brianhempel]

After I ran...

pip3 install b2-ext

Somehow the nb extension config still produced a file with the name "midas" in it.

$ cat /Library/Frameworks/Python.framework/Versions/3.10/etc/jupyter/nbconfig/notebook.d/b2.json
{
  "load_extensions": {
    "midas/index": true
  }
}

B2 wouldn't load. But when I manually changed "midas" to "b2" in the file above, it worked.

I'd make a PR to fix this, but, despite searching for "midas" in the B2 source, I don't know where it went wrong!

Hi Brian, thanks for trying to do the PR! What may have happened is that you had installed b2 at some point in the past, and when you installed the new version, it didn't get updated since the old file was already there. Could verify this by deleting the b2.json file and trying a clean install.

The b2.json file in the published package says "midas".

$ pip3 uninstall b2-ext
$ cat /Library/Frameworks/Python.framework/Versions/3.10/etc/jupyter/nbconfig/notebook.d/b2.json
cat: No such file or directory
$ pip3 cache purge
$ pip3 install b2-ext -vvv
