我一直在尝试在我的可执行脚本中使用 Quicklisp 包。一个(微不足道的)工作示例是:
#!/usr/bin/sbcl --script
(eval-when (:compile-toplevel :load-toplevel :execute)
(ql:quickload "lisp-unit")) ;as explained by another question
(defpackage :test
(:use :cl :lisp-unit))
(format t "This is a test.")
在chmod
包含此代码的文件(称为test.lisp
)之后,我尝试执行它。但是,然后我收到以下错误消息:

我不确定这里发生了什么——如果我尝试从顶层做类似的事情(即启动 SBCL、加载lisp-unit
usingql:quickload
等),我不会得到这样的东西。
