To manage packages conveniently, I set new load-path by (add-to-list 'load-path "c:/emacs/.emacs.d/lisp")
After that I checked load-path lists through C-h v load-path, which confirms "c:/emacs/.emacs.d/lisp" had been added into load-path lists successfully. Then I run (use-pakage xxx) inside my custom init.el, but a warning occurred said
Error (use-package): Cannot load xxx
I rechecked load-path lists and move packages to another one directory mentioned in load-path lists, which is loacted in Emacs installtion directory named site-lisp. THEN (use-pakage xxx) returned to normal and didn't rose a warning.
It's so weird, and I just want to set a custom packages load-path. Does anyone know what goes wrong?
Thanks a lot, but it's not the reason. I have located the point to solve the problem, which is I didn't set org-agenda-files in original init.el (I have another extral init.el for convenience)
