emacs + scheme用C-x C-e好像没什么用

[nesteiner]

用C-x C-e会出现下面那个提示，到geiser那里不能调用
这是我的配置

;; scheme
(setenv "MITSCHEME_LIBRARY_PATH"
        "/usr/bin/chezscheme9.5")
(add-to-list'exec-path "/usr/bin/chezscheme9.5")
(setq scheme-program-name "chezscheme9.5")
(setq geiser-chez-binary "chezscheme9.5")
(setq geiser-active-implementations '(chez))
