Question

我按照https://github.com/Microsoft/LightGBM/wiki/Installation-Guide上的安装指南安装LightGBM。在MinGW shell中，我可以下载git repo，然后cd进入build目录。当我尝试尝试以下命令时：

 cmake -G "MinGW Makefiles" ..

我收到以下错误：

CMake Error at C:/Program Files/CMake/share/cmake-
3.9/Modules/CMakeMinGWFindMake.cmake:12 (message):
sh.exe was found in your PATH, here:

 C:/Program Files/Git/usr/bin/sh.exe

 For MinGW make to work correctly sh.exe must NOT be in your path.

 Run cmake from a shell that does not have sh.exe in your PATH.

 If you want to use a UNIX shell, then use MSYS Makefiles.

 CMakeLists.txt:8 (PROJECT)


 CMake Error: CMake was unable to find a build program corresponding to 
 "MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to 
 select a different build tool.

 CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

我也尝试从我的路径中删除sh.exe。

有人能指出我可能的解决方案吗？我猜我安装的cmake不正确？

Answer 1

您可以尝试两次运行cmake -G "MinGW Makefiles" ..。

Answer 2

一个简单的解决方案：

pip install lightgbm

问题解决了

Answer 3

根据lightgbm中显示的要求在conda中创建一个新环境，然后在jupyter中创建一个环境列表并通过更改内核设置根据您的软件包使用它。

如何创建新的环境？ 康达创建--n py37_64 python = 3.7 还根据lightgbm的32位或64位下载64位用于： config --env --set subdir win--64

并激活特定的环境，这里是py37_64 所以命令将是：激活py37_64

并安装lightgbm 点安装lightgbm

conda安装nb_conda

要在笔记本中使用此内核，必须先停用env并再次将其激活
