如何在 Windows 中使用 pip+mingw 安装 PIL？

Question

我正在尝试使用 pip 和 mingw 安装 PIL。但是失败如下。

我该如何解决这个问题？

Answer 1

INT8、INT16、UINT8、UINT16 定义为 int PIL 源

您可以在 c:\mingw\include\basetsd.h 中添加#ifndef..#endif：

+#ifndef INT8
 typedef signed char INT8;
+#endif

适用于每种类型。 （其中“+”表示添加的行）

它有效。

Answer 2

我建议使用预构建的安装程序。请参阅PIL Unofficial Windows Binary，尽管我强烈推荐Pillow（也可作为安装程序从同一链接获得）。
