我是 brew 新手，直到现在一直在使用它，效果很好。我正在尝试安装 pygame，但它并没有让我通过其中一个依赖项，sdl_ttf. 我正在运行 OS X 10.9（小牛）。最重要的是，我现在已经自己下载并成功安装了该软件包，但 brew 仍然不断要求它并失败。

从我的角度来看，我已经安装了依赖项，所以 brew 应该让我首先继续。一种选择是“说服” brew 我有依赖关系。另一种选择是帮助 brew 再次安装它，所以它很高兴。我对 make 不太了解，但 brew 在该libtool: link: clang部分似乎失败了。如果我可以将 -lpng15 覆盖为 -lpng16，我的预感是它会继续进行（但我可能是错的）。

尝试安装 pygame（和 sdl_ttf 依赖项）：

lpng15 的问题一直留在我的记忆中，因为我以前的安装问题是缺少名为 libpng15 与 libpng16 的库。我认为我的预感是正确的——当我下载 SDL2_ttf-2.0.12 源并运行 ./configure、make、make install 时，它使用的是 lpng16，而不是上面的 lpng15：

SDL2_ttf-2.0.12 的成功（非 brew）输出：

看看最后一部分 - 它使用了 lpng16，可能基于运行的配置：

libtool：链接：gcc -g -O2 -I/opt/local/include/freetype2 -I/usr/local/include/SDL2 -D_THREAD_SAFE -DHAVE_OPENGL -o .libs/glfont glfont.o -Wl,-framework -Wl, OpenGL ./.libs/libSDL2_ttf.dylib -L/opt/local/lib -L/usr/local/lib -lfreetype -lz -lbz2 -lpng16 -lSDL2

记得当 brew 运行这个段时，它试图使用 lpng15 并且找不到它：

ld: library not found for -lpng15

在这种情况下，安装继续顺利进行（但在 brew 之后仍然不知道并希望sdl_ttf从帖子开头开始依赖）：

制作安装输出：

  make install

     /bin/sh ./libtool   --mode=install /usr/bin/install -c   libSDL2_ttf.la '/usr/local/lib'

    If you ever happen to want to link against installed libraries

    specify the full pathname of the library, or use the `-LLIBDIR'
    flag during linking and do at least one of the following:
       - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
         during execution

我认为问题在于您在安装 freetype 后升级了 libpng，所以freetype-config --libs给出了一个错误的答案。brew update; brew upgrade; brew reinstall freetype应该以“正确的方式”解决这个问题。

似乎libpng15可能已被替换为libpng16. 我会尝试从libpng16to创建一个符号链接libpng15（它应该是向后兼容的）。

所以假设 libpng 在/usr/local/lib

#create a link so any requests for lpng15 use lpng16 instead
sudo ln -s /usr/local/lib/lpng16.so /usr/local/lib/lpng15.so

确保您确认这是您机器上库的实际位置（我没有要测试的 OS X 机器）

编辑 根据您的输出/usr/local/lib，尝试以下操作 - 它链接任何丢失的 libpng15 文件以使用 libpng16。

sudo ln -s /usr/local/lib/libpng16.a /usr/local/lib/libpng15.a
sudo ln -s /usr/local/lib/libpng16.dylib /usr/local/lib/libpng15.dylib
