【问题描述】:
这是我第一次使用 ubuntu 和 SML/NJ。当我使用表达式CM.make()时,我想到了这个问题:
Standard ML of New Jersey v110.76 [built: Tue Oct 22 14:04:11 2013]
- CM.make() ;
[autoloading]
[library $smlnj/cm/cm.cm is stable]
[library $smlnj/internal/cm-sig-lib.cm is stable]
[library $/pgraph.cm is stable]
[library $smlnj/internal/srcpath-lib.cm is stable]
[library $SMLNJ-BASIS/basis.cm is stable]
[autoloading done]
stdIn:1.2-1.11 Error: operator and operand don't agree [tycon mismatch]
operator domain: string
operand: unit
in expression:
CM.make ()
我不知道为什么以及哪里错了。
有人可以帮助我吗?
