遇到问题：xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at

执行：xcode-select --install（保证xcode是最新版本）
出现对话框点击安装就好了，然后重新执行xcode-select --install就可以了

cmake …
make -j4

按照官网，此刻已经可以和lightgbm愉快的玩耍了，但是import lightgmb会提示找不到模块
cd …/python-package
sudo python setup.py install --precompile
pip install lightgbm
这样就可以了
