Question

我正在尝试在Cygwin上安装matplotlib，但在安装时我收到错误：

0 [main] python2.7 2968 child_info_fork::abort: address space needed by 'cygEGL-1.dll' (0x420000) is already occupied

我已经尝试杀死所有进程，重新启动我的电脑和rebaseall。它没有帮助。

这是完整的日志：

接下来我该怎么办？

您的问题可能来自后端配置。我建议您禁用setup.py但windowing的每个后端，允许您使用Wx后端进行绘图。这些库可以在Cygwin上找到。你不应该需要Gtk或Tk。

cygEGL-1.dll已被占用
