这个错误可能是因为在创建外键时，引用的表没有被完全定义。请确保在此之前已经定义了course表，并且其中的每个列都已经被定义为主键或唯一键。此外，外键约束应该在列定义的末尾添加，而不是在列之后。你可以尝试将外键约束移到列定义的末尾，例如：

create table student_course (
    scNumber varchar(10) Primary Key,
    cNumber varchar(10),
    cName varchar(10),
    cClass varchar(10),
    cTeacher varchar(10),
    cTerm varchar(20),
    Foreign Key (cNumber) references course(cNumber),
    Foreign Key (cName) references course(cName),
    Foreign Key (cClass) references course(cClass),
    Foreign Key (cTeacher) references course(cTeacher),
    Foreign Key (cTerm) references course(cTerm)
);

这样应该可以解决你的问题。
