我不明白vollib有什么问题。

有人能帮我安装这个软件包吗？

首先，

black\u scholes

不包括在软件包中，因此您不能只导入vollib。第二个

black_scholes

是一个不可调用的模块。正确用法：

import vollib.black_scholes
c = vollib.black_scholes.black_scholes('c',100,90,.5,.01,.2)

在安装和导入时，它表示找不到模块。即使是@Philip的解决方案也不起作用。是否有其他解决方案？在安装和导入时，它表示找不到模块。即使是@Philip的解决方案也不起作用。还有其他解决办法吗？
