python - 无法为 Python 3.6 重新编译 webbot

Question

我尝试重新编译webots python API对于 Python 3.6 64 位，因为我需要该版本的 TensorFlow。我按照步骤尝试使用 MSYS2 和 Windows PowerShell 进行编译。编译提示文件没有找到，尽管它们存在于该位置。

这是 makefile 脚本。 (我不太擅长正则表达式，但我猜它正在将路径设置为我在上图中显示的路径)

MSYS2 和 PowerShell 上的结果:

我认为脚本有问题，但我希望您能指导我用您的双手修复它。谢谢并祝您度过愉快的一天。

P.S:我也希望有人可以帮助我在编译时强制使用特定版本的python。

我相信这个问题已在此 PR 中得到解决:https://github.com/omichel/webots/pull/108

问题是在 Makefile 中错误使用了空格转义变量，应删除 $(WEBOTS_HOME_PATH) 路径周围的引号。
