Wrong type argument: hash-table-p, nil

[hongyi-zhao]

On Ubuntu 20.04.2 LTS, I installed historian.el with use-package as follows:

(use-package historian)
(use-package ivy-historian)


(use-package ivy
  :diminish ivy-mode
  :init
  (ivy-mode +1)
  (historian-mode +1)

  :config
  (ivy-historian-mode +1)
  (setq ivy-historian-recent-boost most-positive-fixnum)
  )

But the above configuration will cause so many errors like the following:

Wrong type argument: hash-table-p, nil

Any hints for this problem?

This typically means your historian-save-file is malformed. What does it contain?

I can't find the file at all:

werner@X10DAi-00:~/.emacs.d$ find . -type f -name '*historian-save-file*'
werner@X10DAi-00:~/.emacs.d$

Just chiming in that this solved the issue for me.

I did C-h v and inspected the historian-save-file variable, which pointed to ~/.emacs.d/.historian. That file contained a single line with nil. Removing the file fixed the error (but seems to have borked my history—a small price to pay 🙂)

Thanks!

Thank you for pointing this out. Obviously, in the case of Emacs, the find command by me is out of place.

Would you please describe the phenomenon in detail? Does this often happen, or just once?
