json.decoder.JSONDecodeError

Closed this issue · 2 comments

As in the README, I created a jupyter_config.json file in the jupyter --config-dir, and as a test, I added:

{
  "CondaKernelSpecManager": {
    "env_filter": "regex"
}

... which produced the following error:

    Traceback (most recent call last):

    json.decoder.JSONDecodeError: Expecting ',' delimiter: line 5 column 1 (char 59)

If the JSON file must include more than what is listed above, it would help to have that info in the README

Could you have a second look at your config file?

Your snippet is missing a }:

{
  "CondaKernelSpecManager": {
    "env_filter": "regex"
  // Missing closing curly brace here
}

You can check if your config file is correct JSON by running:

python -c "import json; import pathlib; print(json.loads(pathlib.Path('jupyter_config.json').read_text()))"

Yeah, that's it. I should have paid more attention to the syntax of the example in your README.
