我正在尝试安装旧版本的 nokogiri，但我无法指定格式：

我在用着 

gem install nokogiri -v 1.5.2 -- --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

但这不是正确的语法。你知道怎么做吗？

错误

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

您只指定了lib要使用的目录，请尝试指定include目录：

gem install nokogiri -v 1.5.2 -- \
                 --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib \
                 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include

您可以同时指定两者：

gem install nokogiri -v 1.5.2 -- \
                 --with-iconv-dir=/usr/local/Cellar/libiconv/1.13.1

看起来Nokogiriiconv在 1.5.2 和 1.5.5 版本之间的查找方式发生了一些变化，这可以解释为什么您能够安装最新版本但不能安装 1.5.2。

我只是安装了自制软件，并使用它brew link inconv来创建必要的符号链接来编译 gem。

$brew link libiconv
Linking /usr/local/Cellar/libiconv/1.13.1... 18 symlinks created
$gem install nokogiri -v 1.5.2
