I followed the steps, but something is not in order with the jupyter_notebook_config.json file?
I get the following output when trying to start $ jupyter notebook:
[E 20:54:30.273 NotebookApp] Exception while loading config file /home/rainer/.jupyter/jupyter_notebook_config.json
...
json.decoder.JSONDecodeError: Expecting ',' delimiter: line 5 column 5 (char 107)
I’ve edited the title. You’ve already installed Jupyter successfully. Now you’re just trying to run it. You don’t actually need any special configurations: you can run jupyter-notebok in any directory and it’ll start the jupyter server there. If you intend to use Jupyter from the same machine (i.e. locally), you don’t need any configuration.
