python - 在 cygwin 中安装 matplotlib 时出错

Question

我已经尝试将 matplotlib 安装到我的 cygwin 环境中。这是我桌面上安装的错误消息。但是，此安装在我的笔记本电脑上非常成功。两者都使用相同版本的所有内容。有人知道如何解决它吗？

我让 matplotlib 在 Cygwin 下工作，如下所示。 1:从源代码安装 libpng(使用通常的 configure、make、make install)； 2:使用 pip install matplotlib 安装 matplotlib(我确实必须更改 ._tri 中的变量名称，如下所述:https://github.com/matplotlib/matplotlib/issues/2463 - 然后一切正常)。
