将 chezschme 运行 设置为 geiser-default-implementation
Set chezschme run as geiser-default-implementation
我安装了 chezscheme
$ chezscheme
Chez Scheme Version 9.5

> (define a (list 4 5 6 ))

(9 5 6)
并将其配置为 geiser-default-implementation
(require 'geiser)
(setq geiser-active-implementations '(chez guile racket chicken mit chibi gambit))
(add-hook 'scheme-mode-hook 'geiser-mode)
(setq geiser-default-implementation 'chez)
尽管如此，当使用 org src 发出 C-c C-c 时
#+begin_src scheme :session sicp :lexical t
(define a (list 2 3 4))
(set-car! a 9)
a
#+end_src
#+RESULTS:
缓冲了很久提示在minibuffer中'chez go and up'
但 运行 MIT 方案。
错误：

;Warning: Invalid keyword: "/home/me/.emacs.d/.local/straight/build/geiser/scheme/chez/geiser/geiser.ss"
;Warning: Unhandled command line options: ("/home/me/.emacs.d/.local/straight/build/geiser/scheme/chez/geiser/geiser.ss")
附加：
添加geiser-chez-binary
(setq geiser-active-implementations '(chez guile))
(setq geiser-chez-binary "chez")
(add-hook 'scheme-mode-hook 'geiser-mode)
(setq geiser-default-implementation 'chez)
和运行
#+begin_src scheme :session sicp :lexical t :results output
(define b (list 3 4))
#+end_src
它报告
apply: Searching for program: No such file or directory, chez
然后我将 chez 附加到 org-babel-do-load-languages 并将关键字方案更改为 chez
#+begin_src chez :session sicp :lexical t :results output
(define b (list 3 4))
#+end_src
它报告：
No org-babel-execute function for chez!
删除了 mit-scheme 包并且它有效
默认情况下，Geiser 认为 Chez Scheme 的可执行文件是 scheme，但事实并非如此，Chez Scheme 使用 chez 而 Mit Scheme 使用 scheme 和 mit-scheme。您需要将以下内容放入您的 Emacs 初始化文件中：
(setq geiser-chez-binary "chez")
这里是geiser-chez-binary的文档字符串（我已经把它改成了chez）：
geiser-chez-binary is a variable defined in `geiser-chez.el'.
Its value is "chez"
Original value was "scheme"
Documentation:
Name to use to call the Chez Scheme executable when starting a REPL.
You can customize this variable.
我安装了 chezscheme
