我正在尝试在 Windows 上的 SBCL 下使用 ASDF 加载第一个程序：(asdf:load-system "dependencies")。 ASDF 能够找到目录和 .asd 文件，但会产生警告和错误：
* (asdf:load-system "dependencies")
WARNING: System definition file #P"C:/Users/davyp/AppData/Local/lxss/root/quicklisp/dists/quicklisp/software/cl-ppcre-20190521-git/cl-ppcre.asd" contains definition for system "cl-ppcre-test". Please only define "cl-ppcre" and secondary systems with a name starting with "cl-ppcre/" (e.g. "cl-ppcre/test") in that file.

我的 .conf 文件包含单个条目：(:directory #P"D:/Users Data/Dave/SW Library/AI/Dependencies/");这是 .asd 文件中的 defsystem：
(defsystem "dependencies"
:description "dependencies: A Common Lisp system for detecting ~
inter-dependencies between a project's files."
:version "1"
:author "David Brown <davypough@gmail.com>"
:licence "Public Domain"
:depends-on ("alexandria" "cl-ppcre")
:components ((:file "dependencies"))) ;ie, dependencies.lisp
对于警告，看起来 ASDF 正在查找与另一个程序相关联的 cl-ppcre，即使首先使用 (asdf:clear-source-registry) 清除了注册表。该错误似乎与某种循环有关。感谢您帮助解决问题。
