Spacemacs的scheme layer和racket layer分别在scheme-mode和racket-mode下无法自动补全代码，该如何处理

(auto-completion :variables
                 auto-completion-enable-sort-by-usage t
                 auto-completion-enable-snippets-in-popup t)

自动补全只在REPL下有效，scheme layer和racket layer分别在scheme-mode和racket-mode下无法自动补全代码

问题已解决，在spacemacs:Issue找到解决方法

scheme layer company not work #10561

(defun scheme/post-init-company ()
  ;; Geiser provides completion as long as company mode is loaded.
  (spacemacs|add-company-backends :backends geiser-company-backend :modes scheme-mode))

进入scheme-mode同时开启REPL，在scheme-mode中company自动补全就可以用了。

spacemacs默认的scheme layer进入scheme-mode同时开启REPL，需要补全要使用TAB key，在mini buffer会有提示，但这效率也太低了些。
