先贴上我的安装过程代码 我是通过homebrew&gcc安装的 如果不是通过gcc安装的可以参考文末最后一行网址 在terminal中输入如下代码:
brew install cmake
brew install gcc
git clone --recursive https://github.com/microsoft/LightGBM ; cd LightGBM
export CXX=g++-9 CC=gcc-9 # replace "9" with version of gcc installed on your machine
mkdir build ; cd build
cmake ..
make -j4
然后输入
cd ../python-package
sudo python setup.py install --precompile
pip install lightgbm
如果还遇到其它问题可以参考 https://blog.csdn.net/wgc7998/article/details/80302174 还有 https://lightgbm.readthedocs.io/en/latest/index.html
