我想下载LightGbm，因此我关注了该网站。但是突然因错误而停止了。请发布解决方案。

谢谢https://lightgbm.readthedocs.io/en/latest/Installation-Guide.html#macos

错误：

cmake ..
CMake Error at /usr/local/Cellar/cmake/3.13.0/share/cmake/Modules/CMakeDetermineCCompiler.cmake:48 (message):
  Could not find compiler set in environment variable CC:

  gcc-7.
Call Stack (most recent call first):

Answer 1

您的环境变量CC设置为gcc-7，但是无法使用$ PATH变量访问此编译器。

尝试在终端上写入gcc-7，会出现Command not found错误。
