我无法使用 scheme repl 执行它的示例.我试图运行给定的部分示例，出现如下错误

I'm not able to execute it's example with scheme repl. I tried to run given example of section, I got an error as given below

1 ]=> (define wave2 (beside wave (flip-vert wave)))

;Unbound variable: wave

即使在书中，painter 也作为原始程序给出.当我运行它时，它也抛出了一个错误

Even In book, painter is given as primitive procedure. when I ran it, it thrown an error too

1 ]=> painter

;Unbound variable: painter

我不知道，我哪里做错了?我可以使用 scheme repl 运行这些示例吗?

推荐答案

使用DrRacket安装sicp包如下:

Use DrRacket to install the sicp package like this:

打开包管理器:在 DrRacket 中选择菜单文件"，然后选择包管理器...".

Open the Package Manager: in DrRacket choose the menu "File" then choose "Package Manager...".

在Do What I Mean"选项卡中找到文本字段并输入:sicp"

In the tab "Do What I Mean" find the text field and enter: "sicp"

最后点击安装"按钮.

测试一下.确保 DrRacket 在左下角有Determine language from source".编写以下程序并点击运行:

Test it. Make sure DrRacket has "Determine language from source" in the bottom left corner. Write the following program and click run:

#lang scp

(inc 42)

预期输出为 43.
