Question

我正在尝试在我的Mac上安装webrat，但是我遇到了错误，即iconv.h缺失了。这是日志：

    Building native extensions.  This could take a while...
ERROR:  Error installing webrat:

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.1 for inspection.

奇怪的是，iconv.h已经在/ opt / local / include /目录中。

有人可以推荐一个解决方案吗？

Answer 1

好的，我自己解决了。经过几天的研究和尝试，我发现，我的g ++和gcc的安装被打破了。我已经通过macports安装了g ++的更新，并且在我当前用户的.profile文件中，来自macports的PATH var中有一个值。我删除它，现在它可以工作。

PATH var应如下所示：

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

Nokogiri网站提供更多帮助，使用 macports 或自制安装Mac OS X：
