libiconv is missing.

你能帮我吗？

Answer 1

我安装了Yosemite OSX 10.10和XCode 6.1.

我得到了安装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 

然后我做了:

$ 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. 

所以我必须这样做:

$ brew tap homebrew/dupes

然后我做了:

$ 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 

当我尝试安装tiny_tds时,这让我超越了原来的错误"libiconv is missing".我现在得到了一个不同的错误:"freetds缺失"

$ brew install freetds 

最后:

$ gem install tiny_tds
