Numba和llvmlite不会安装在Sage Cygwin上

问题描述

即使在SageMath 9.1 Shell的管理员下,我也无法安装numba (buildchain可能已损坏,是否有解决方法-conda install?)。 Numba将有助于重塑矩阵和内容

所以这基本上是一个错误

$ sage --pip install numba

解决方法

我认为这里的问题很清楚:llvmlite是numba的依赖项,不支持Cygwin。

似乎在llvmlite构建脚本中,有an explicit check个受支持的平台,该平台当前不包括cygwin。但是,最近有些pull request添加了cygwin支持,但尚未进行审核。

P.S。 conda不支持cygwin
