无法在 Windows 64（Py3.6）上从源代码构建 matplotlib - png 错误

Question

从网上的大量研究来看，在 Windows 上从源代码安装 matplotlib 似乎并不简单，而且很多都有问题。虽然许多 SO 帖子已经解决了问题，但我仍然遇到一个我似乎无法解决的问题。

从 GitHub 克隆 matplotlib 存储库后，我按照 matplotlib 网站的说明进行安装，并在尝试运行 python setup.py develop 时得到以下输出日志：

============================================================================
                        * The following required packages can not be built:
                        * png * Please check http://gnuwin32.sourceforge.net
                        * /packages/libpng.htm for instructions to install
                        * png

问题似乎是 libpng。

我尝试使用推荐的适用于 Windows 的 scipt (https://github.com/jbmohler/matplotlib-winbuild)，但出现 VS2010 not found 错误。当我尝试安装它时，Microsoft Python Tools 网站提示 Py3.6 64-bit 不支持早于 VS2015 的版本。

我还尝试使用来自 http://gnuwin32.sourceforge.net/packages/libpng.htm 的二进制文件手动安装 libpng 但即使安装成功，我也会遇到同样的错误。

请问有解决办法吗？或者对于如何为 Windows 安装 matplotlib 有什么很好的参考 - 似乎这里的权威和全面的指南对社区非常有用，因为用户有很多问题在这方面苦苦挣扎！

任何帮助欢迎感谢！

Answer 1

我设法使用 these instructions 从 Visual Studio 2017 的源代码构建 matplotlib 3.1.1。

其中一个技巧是某些库需要重命名，例如 libpng.lib -> png.lib 和 zlib.lib -> z.lib。
