在OSX 10.10上安装tiny_tds错误优胜美地

Question

互联网，我不知道该怎么做。升级到优胜美地后，我无法安装tiny_tds

$ gem install tiny_tds 
Building native extensions. This could take a while... 
ERROR: Error installing tiny_tds: 
ERROR: Failed to build gem native extension. 

/Users/jpolley/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb 
checking for iconv_open() in iconv.h... no

----- 
libiconv is missing.

你能帮忙吗？

Answer 1

我安装了优胜美地OSX 10.10和XCode 6.1。

我收到了安装xCode命令工具的建议，允许我安装libiconv。

然后brew安装libiconv。

然后brew链接libiconv。

$ xcode-select --install 
xcode-select: error: command line tools are already installed, 
use "Software Update" to install updates 

然后我做：

$ brew install libiconv 
Error: No available formula for libiconv Apple distributes libiconv with OS X, 
you can find it in /usr/lib. Some build scripts fail to detect it correctly, 
please check existing formulae for solutions. 

所以我不得不这样做：

$ brew tap homebrew/dupes 

然后我做：

$ brew link libiconv 
Warning: libiconv is keg-only and must be linked with --force 
Note that doing so can interfere with building software. 

$ brew link libiconv --force 
Linking /usr/local/Cellar/libiconv/1.14... 16 symlinks created 

这让我过去我原来的错误“ libiconv丢失“，当试图安装tiny_tds。我现在有一个不同的错误：“freetds的缺失”

$ brew install freetds 

最后：

$ gem install tiny_tds
