But I still can't find out the specific > configuration which caused the problem. I found the reason: it is caused by the following configuration: ``` (straight-use-package `(swiper :type git :host github :repo "abo-abo/swiper" :pre-build ( ;("bash" "-c" "cd ~/.emacs.d/straight/repos/swiper") ;https://github.com/abo-abo/swiper/issues/2886#issuecomment-860605327 ("make" "deps") ("make" "compile") ))) (require 'ivy) (ivy-mode 1) (setq ivy-use-virtual-buffers t) (setq ivy-count-format "(%d/%d) ") ``` But I still can't figure out why this configuration will trigger the above problem.
