Thanks, the problem is solved.
## Possible cause
Initially, I have emacs installed and ~/.guix-profile/etc/profile sourced.
but when I type "guix package -I | grep emacs". I don't see emacs package
(strange).
So I reinstall emacs : guix install emacs. Then I can see 2 emacs-27.1
installation
```
$ which -a emacs
/home/dev_1/.guix-profile/bin/emacs
/home/dev_1/.guix-profile/bin/emacs
/run/current-system/profile/bin/emacs
$ ls -l /home/dev_1/.guix-profile/bin/emacs
lrwxrwxrwx 8 root root 64 Jan 1 1970 /home/dev_1/.guix-profile/bin/emacs
-> /gnu/store/6mw831p6pccqwr3k3qanr6pmhcq0qym6-emacs-27.1/bin/emacs
$ ls -l /run/current-system/profile/bin/emacs
lrwxrwxrwx 2 root root 64 Jan 1 1970
/run/current-system/profile/bin/emacs ->
/gnu/store/yy66pbp3h5mw5sv7hrl1778skapszq7k-emacs-27.1/bin/emacs
```
Now $EMACSLOADPATH contains 6 paths with
"$GUIX_PROFILE/share/emacs/site-lisp" in it:
```
$ echo $EMACSLOADPATH
/home/dev_1/.guix-profile/share/emacs/site-lisp:/home/dev_1/.guix-profile/share/emacs/27.1/lisp:/home/dev_1/.guix-profile/share/emacs/site-lisp:/home/dev_1/.guix-profile/share/emacs/27.1/lisp:/run/current-system/profile/share/emacs/site-lisp:/run/current-system/profile/share/emacs/27.1/lisp
```
Before $EMACSLOADPATH contains only 2 paths without
"$GUIX_PROFILE/share/emacs/site-lisp" in it.
I think my first emacs installation should has something break,so
$EMACSLOADPATH isn't correctly set.
Thanks again
