pinentry start report error ‘/tmp/emacs1000’ is not a safe directory

["numbchild@gmail.com" <numbchild@gmail.com>]

I configure pinentry:

#+begin_src emacs-lisp
(use-package pinentry
  :ensure t
  :init (pinentry-start))
#+end_src


But Emacs raise error:

#+begin_example
Debugger entered--Lisp error: (error "‘/tmp/emacs1000’ is not a safe
directory because i...")
  signal(error ("‘/tmp/emacs1000’ is not a safe directory because i..."))
  error("`%s' is not a safe directory because %s" "/tmp/emacs1000" "it is a
symlink")
