【问题描述】：

我整个晚上都在我的 mac 终端窗口上尝试解决这个问题。我在我的 Mac 上使用“brew install optipng”安装 optipng 时遇到困难。

这是 'brew install optipng' 后来自终端的日志

==> Downloading https://downloads.sourceforge.net/project/optipng/OptiPNG/optipn
Already downloaded: /Library/Caches/Homebrew/optipng-0.7.5.tar.gz
==> ./configure --with-system-zlib --prefix=/usr/local/Cellar/optipng/0.7.5 --ma

make[1]: *** [optipng] Error 1
make: *** [install] Error 2

当然，我按照 github 的链接，尝试使用 brew doctor、brew doctor 建议的说明，甚至是 brew update 去某个地方。

我将在此处包含来自 brew doctor 的一些警告，并在需要时跟进整个日志（我不想用不必要的信息堵塞帖子）。

Warning: gettext files detected at a system prefix
These files can cause compilation and link failures, especially if they
are compiled with improper architectures. Consider removing these files:

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

任何帮助将不胜感激。

谢谢

【解决方案1】：

这对我来说真的很令人沮丧，但我设法解决了自制医生问题，方法如下：

警告：Python 安装在 /Library/Frameworks/Python.framework

我安装了多个版本的 Python，所以我继续删除了这个：

sudo rm -rf /Library/Frameworks/Python.framework

警告：您已安装 MacPorts 或 Fink：

这个比较难，我的 Macports 有 PATH 问题，所以我不得不用终端添加它所在的路径，然后从那里删除它。

警告：在 /usr/local/lib 中发现了未编译的 dylib。

我在终端上用 rm 删除了这些。

警告：在 /usr/local/lib 中发现未编译的 .la 文件。

已删除。

在 /usr/local/lib 中找到未编译的静态库。

如果我没记错的话，我在这里做了 brew prune。

我的所有 PATH 文件中的权限也从 root 更改为我。

执行此操作后 optipng 安装正常。
