windows下安装llama-cpp-python失败的处理

想尝试python使用llama-cpp的功能,在windows下安装llama-cpp-python时,会报错。

PS C:\Users\xxxx> pip install llama-cpp-python

错误信息提示是找不到nmake。网上查找了一下,nmake是VisualStudio自带的开发工具,但是为了避免安装庞大的VS,我们只需要安装Vs build tools,记得要选中“使用C++的桌面开发”。

安装成功后,可以看到系统里已经有nmake.exe了,路径也无需配置。

再次使用pip安装llama-cpp-python,成功编译。
