OSError,image not found appears in lightGBM reference

A rookie. After installing lightGBM with pip, there is a problem with the reference (the system is High Sierra)

In [3]: import lightgbm

  Reason: image not found

reinstallation will not solve the problem, and then try another installation method, but cmake installation failed. For more information, please see

. To put it simply, the function of Homebrew can hardly be used, and there is always a permission problem. Also ask the gods to give advice, even if there is no specific plan can also be a simple analysis of the reasons, every bit of your knowledge can give me a lot of help, I hope you do not hesitate to give advice!
