Numba和llvmlite不会安装在sage cygwin上

Question

即使在SageMath 9.1 Shell的管理下，我也无法安装numba （构建链可能已断开，是否有解决方法--conda install？）。 Numba将帮助重塑矩阵和其他东西

这基本上是一个错误：

$ sage --pip install numba

Answer 1

我认为这里的问题相当清楚：llvmlite是numba的一个依赖项，不支持Cygwin

在llvmlite构建脚本中，似乎有an explicit check个受支持的平台，目前不包括cygwin。然而，最近有一个{a2}添加了cygwin支持，但尚未对其进行审查

p.S.康达不支持cygwin
