common-lisp - 从 Lispworks 加载 `rutils` 时出错

Question

我可以发誓这以前有用。

CL-USER 7 > (ql:quickload 'rutils)
To load "rutils":
  Load 1 ASDF system:
    rutils
; Loading "rutils"
[package editor-hints.named-readtables]..

[package rutils.core].............................
[package rutils.misc].............................

.

Error: Redefining macro := visible from package KEYWORD { *handle-warn-on-redefinition* is :ERROR }
   1 (continue) Redefine it anyway.
   2 Try loading /Users/agam/.cache/common-lisp/lw-7.1.0-macosx-x64/Users/agam/quicklisp/dists/quicklisp/software/rutils-20180228-git/core/abbr.64xfasl again.

   4 Try loading another file instead of /Users/agam/.cache/common-lisp/lw-7.1.0-macosx-x64/Users/agam/quicklisp/dists/quicklisp/software/rutils-20180228-git/core/abbr.64xfasl.
   5 Recompile abbr and try loading it again
   6 Retry loading FASL for
   #.
   7 Continue, treating loading FASL for
   #
     as having been successful.
   8 Retry ASDF operation.
   9 Retry ASDF operation after resetting the configuration.
  10 Retry ASDF operation.
  11 Retry ASDF operation after resetting the configuration.
  12 (abort) Give up on "rutils"
  13 Return to top loop level 0.

Type :b for backtrace or :c  to proceed.
Type :bug-form "" for a bug report template or :? for other options.

有什么线索吗？

Answer 1

I can make it go away by running CL-USER 10 > (setf *handle-warn-on-redefinition* :warn) but is that the right way?

是的，这是解决这个问题的一种方法。例如，您可以在主目录中的文件 .lispworks 中进行设置。默认情况下，LispWorks 会尝试保护关键字包(以及其他一些包)免受用户更改。

另请注意，您可以使用第一次重新启动来重新定义它并继续。
