用M-x helm-bibtex获取到entries，但是想要获取action的时候提示:“No Available actions”
也有试过用最小配置，还是一样的，最小配置如下：
(require 'package)
(setq package-archives '(("melpa" . "https://melpa.org/packages/")
("org" . "https://orgmode.org/elpa/")
("elpa" . "https://elpa.gnu.org/packages/")))
(package-initialize)
(unless package-archive-contents
(package-refresh-contents))
;; Initialize use-package on non-Linux platforms
(unless (package-installed-p 'use-package)
(package-install 'use-package))
(require 'use-package)
(setq use-package-always-ensure t)
(setq bibtex-completion-bibliography "/Users/hoo/Bib/hello.bib")
(use-package helm-bibtex
:config
(setq bibtex-completion-bibliography bib-files-directory
bibtex-completion-library-path pdf-files-directory
bibtex-completion-pdf-field "File"
bibtex-completion-notes-path org-directory
bibtex-completion-additional-search-fields '(keywords))
:bind
(("C-c n B" . helm-bibtex)))
网上搜了很久没有解决办法，能提供思路也很感谢
