从clsql-20110829版的quicklisp加载clsql-mysql时出现SBCL加载错误

Question

对于SBCL 1.0.45，使用quicklisp加载clsql-mysql时，我得到一个关于"no symbol“的错误，这似乎会导致接口加载失败。具体地说，错误是：

clsql-mysql包

文件: /home/blake/quicklisp/dists/quicklisp/software/clsql-20110829-git/db-mysql/mysql-sql.lisp

在: DEFPACKAGE #:CLSQL-MYSQL

 (DEFPACKAGE #:CLSQL-MYSQL

   (:USE #:COMMON-LISP #:CLSQL-SYS #:MYSQL #:CLSQL-UFFI)

   (:EXPORT #:MYSQL-DATABASE)

还有没有人遇到过这个问题？

Answer 1

看起来您正在从Quicklisp外部使用clsql。你在过去的某个时候下载过吗？(asdf:system-source-directory "clsql")显示了什么？

可通过Quicklisp加载的clsql-sys确实有一个名为ESCAPED的符号。
