让SICP在球拍上运行: excercise 4.48，无法让load()工作

Question

我在试着解决SICP的4.48段节选。我试图让加载机制运行，即加载CH4-mcval.scm(期望所有定义都可用)，但我似乎没有正确的语法。

我试过了

#lang planet neil/sicp和#lang sicp，尝试了(load "ch4-mceval.scm")和(#%require "ch4-mceval.scm")，都没有成功。

我有一个简单的解决方案，我基本上把这两个文件合并成一个，但我发现这真的很难看。

任何帮助都将不胜感激。

启动ch4-ambeval.rkt，尝试加载CH4-mcval.rkt

#lang planet neil/sicp ; added 07 MAR 2022
;;;;AMB EVALUATOR FROM SECTION 4.3 OF
;;;; STRUCTURE AND INTERPRETATION OF COMPUTER PROGRAMS

;;;;Matches code in ch4.scm.
;;;; To run the sample programs and exercises, code below also includes
;;;; -- enlarged primitive-procedures list
;;;; -- support for Let (as noted in footnote 56, p.428)

;;;;This file can be loaded into Scheme as a whole.
;;;;**NOTE**This file loads the metacircular evaluator of
;;;;  sections 4.1.1-4.1.4, since it uses the expression representation,
;;;;  environment representation, etc.
;;;;  You may need to change the (load ...) expression to work in your
;;;;  version of Scheme.
;;;;**WARNING: Don't load mceval twice (or you'll lose the primitives
;;;;  interface, due to renamings of apply).

;;;;Then you can initialize and start the evaluator by evaluating
;;;; the two lines at the end of the file ch4-mceval.scm
;;;; (setting up the global environment and starting the driver loop).
;;;;In the driver loop, do
;(define (require p)
;  (if (not p) (amb)))


;;**implementation-dependent loading of evaluator file
;;Note: It is loaded first so that the section 4.2 definition
;; of eval overrides the definition from 4.1.1
(load "ch4-mceval.scm")

Answer 1

我试过mceval.scm in DrRacket，load似乎没什么问题。

我没有planet neil/sicp，因为球拍(>8.0)已经有一个内置的sicp语言。
