在Cygwin上安装freetype（matplotlib的先决条件）：不可能执行任务？

Question

我无法在freetype上安装matplotlib) {{1>}的{em>先决条件，尽管我按照freetype2.html上的说明操作了所有建议 - 在前几页的结果中 - Google search，尤其是此stack-overflow thread。

有人可以详细说明他们在Cygwin,上安装freetype/matplotlib的成功吗？

我的设置：

• Cygwin 1.7.35（0.287 / 5/3）i686
  
• 

我做了什么？

• 在Cygwin的设置（setup-x86.exe）中，我输入了Cygwin和freetype并安装了所有找到的包（及其依赖项）。
  

• 然后：
  

  pkg-config,

• 和

  $ apt-cyg search freetype Searching downloaded packages... cygwin64-freetype2 girepository-x11 libfontconfig-devel libfreetype-devel libfreetype-doc libfreetype6

  $ for i in cygwin64-freetype2 girepository-x11 libfontconfig-devel libfreetype-devel libfreetype-doc libfreetype6 ; do echo "$i" ; apt-cyg install $i ; done

  cygwin64-freetype2 Package cygwin64-freetype2 is already installed, skipping girepository-x11 Package girepository-x11 is already installed, skipping libfontconfig-devel Package libfontconfig-devel is already installed, skipping libfreetype-devel Package libfreetype-devel is already installed, skipping libfreetype-doc Package libfreetype-doc is already installed, skipping libfreetype6 Package libfreetype6 is already installed, skipping

• 验证

  $ apt-cyg install pkg-config Package pkg-config is already installed, skipping

• 所以，似乎我的Cygwin中安装了freetype。
  

• 唉：
