ruby - 在 OSX 10.10 Yosemite 上安装 tiny_tds 时出错

Question

互联网，我不知道该做什么。升级到 Yosemite 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
checking for iconv_open() in -liconv... no
-----
libiconv is missing.

你能帮忙吗？

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，以允许我安装 libiconv。

然后brew install libiconv。

然后brew link 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 

这让我在尝试安装 tiny_tds 时克服了最初的错误“libiconv is missing”。我现在遇到了一个不同的错误:“freetds is missing”

$ brew install freetds 

最后:

$ gem install tiny_tds
