Check list

• Read the "Avoiding Common Emacs Traps" section in
  https://github.com/millejoh/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
• Does IPython works from the web browser?
• Confirm the problem was not due to badly compiled
  files by removing all the *.elc files from source directory of EIN and
  its dependencies.
• Confirm that the libraries are loaded as expected and are at the required version.

Description of the problem you have

After I called ein:notebooklist-new-notebook-with-name, it gave the message that

ein: [warn] No recorded kernelspecs for 8888
helm-M-x: Wrong type argument: ein:$notebooklist, nil

So I opened the debugger and the *BackTrace* buffer shown that

Debugger entered--Lisp error: (wrong-type-argument ein:$notebooklist nil)
  signal(wrong-type-argument (ein:$notebooklist nil))
  ein:notebooklist-new-notebook-with-name("test" "default" 8888)
  funcall-interactively(ein:notebooklist-new-notebook-with-name "test" "default" 8888)
  call-interactively(ein:notebooklist-new-notebook-with-name record nil)
  command-execute(ein:notebooklist-new-notebook-with-name record)
  helm-M-x(nil #("ein:notebooklist-new-notebook-with-name" 0 39 (match-part "ein:notebooklist-new-notebook-with-name")))
  funcall-interactively(helm-M-x nil #("ein:notebooklist-new-notebook-with-name" 0 39 (match-part "ein:notebooklist-new-notebook-with-name")))
  call-interactively(helm-M-x nil nil)
  command-execute(helm-M-x)

Steps to reproduce the problem

1. M-x ein:jupyter-server-start
2. M-x ein:notebooklist-new-notebook-with-name

Expected output

Your EIN configuration (in .emacs.d/init.el or somewhere else)

I use default config from Spacemacs.

Your IPython configuration

1. What is your IPython version? (run ipython --version):
   6.2.1

2. How do you start IPython? (e.g., ipython notebook --port 9999):
   M-x ein:jupyter-server-start

3. What is your IPython notebook port number or URL?:
   http://127.0.0.1:8888

Additional information (if any)

I have looked at #464, but I did not set up any proxy.

[dickmao]

Sorry about this. Thanks for reporting a real bug.

[kenkangxgwe]

It seems the problem continues. I am still getting the same message

ein: [warn] No recorded kernelspecs for 8888
helm-M-x: Wrong type argument: ein:$notebooklist, nil

Of course, I have reinstalled the package and deleted all the compiled byte code.

[dickmao]

Please go into directory M-: (ein:source-dir), and ensure the change made in #486 is there.

[kenkangxgwe]

There's no such a function or variable called (ein:source-dir)

Sorry, M-: ein:source-dir

[kenkangxgwe]

Ok, I checked my the file under the ein:source-dir, which is ~/.emacs.d/elpa/develop/ein-20190315.1546/ein-notebooklist.el:434. It had already been the latest version:

(list url-or-port kernelspec name)))

[dickmao]

I get a similar error when I didn't first ein:run or ein:login.

This command should not return nil

M-: (ein:notebooklist-list-get (ein:url 8888))

Otherwise, I'm afraid I cannot diagnose your problem.
