请问可以在ubuntu18.04运行吗？我其他的环境都和说明中一致了，但是最后运行就是报错，怀疑是系统的问题，我用的18.04的。

I am fairly sure the code can run on ubuntu 18.04. Can you be more specific about the error message?

The above error appeared when I run 'make' after cd $COCOAPI/PythonAPI, and my server is Ubuntu 18.04.Could u help me and give any advice? Thx a lot!
