在 Windows 下的 Conda 环境中pip install一些需要现场编译的库时经常会报错;
Building wheel for pyopenjtalk (pyproject.toml) ... error

上图为安装pyopenjtalk时的报错信息。
我之前遇到这种问题的解决方法是直接下载已经在Windows上编译好的whl文件;然后;
pip install xxx.whl
然而该网站并没有编译好的pyopenjtalk包;因此这次必须解决该错误。
根据微软官方问答平台中的说法;应该是Conda环境下pip的构建工具选择错误。
在pip install之前执行;
SET DISTUTILS_USE_SDK=1 & ;C:Program Files (x86)Microsoft Visual Studio2019BuildToolsVCAuxiliaryBuildvcvarsall.bat; x64
注意vcvarsall.bat的路径因人而异。
至于为什么要这么做;可以参考下sklearn的高级安装文档。
