本文主要是介绍【ocean】报错*Error* quotient: can‘t handle (nil / nil)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
- 这个情况比较复杂，有很多种情况，一般nil代表没有值，ciw中会具体提示哪一行错误，但如果是一个procedure，他不会提示得那么仔细
Error* quotient: can’t handle (nil / nil)
Error load: error while loading file - “xxx.ocn” at line 183 - 网上看还有error，提示值晶体管值不对，原来读文件时候多读了一个数，本来是w,l,mul，我还继续用fscanf读了一个其他的配置，导致后面W和L被冲掉了，debug没有经验可以将fscanf读出来的W和L再printf到CIW上看看具体是多少
- 补充一下，fscanf(file …)，file不存在也可能报这个错误，首次检查一下文件是否存在，路径对不对
