问题描述
在1.0上添加并构建KNITRO.jl似乎可行，但是在运行using时出现错误.
Adding and building KNITRO.jl on 1.0 seems to work, but when running using I get an error.

推荐答案
假设您正在 github 并读取您的错误消息，它在KNITRO.jl的第37行失败:
Assuming you're grabbing the copy on github and reading your error message, it fails at line 37 of KNITRO.jl:
type KnitroProblem
type已过时.它是[mutable] struct.当前版本显然是用于v0.6的.如果尝试使用v0.7，它应该会抛出多个弃用警告.
type is deprecated. It is [mutable] struct.The current version is for v0.6 apparently. If you try with v0.7 it should toss several deprecation warnings.
