Question

我刚刚删除了Macports所以现在我使用Homebrew。现在我正在尝试使用typhoeus ruby gem，它依赖于multicurl。

当我尝试执行我的rubyscript时，我收到以下错误消息：

/Users/myusername/.rvm/gems/ruby-1.9.3-p125/gems/ffi-1.0.11/lib/ffi/library.rb:121:in `block in ffi_lib': Could not open library 'libcurl': dlopen(libcurl, 10): image not found.

显然有些文件丢失了。

当我执行$ otool -L /usr/local/bin/curl时，我得到：

/usr/local/lib/libcurl.4.dylib (compatibility version 7.0.0, current version 7.0.0)
/opt/local/lib/libidn.11.dylib (compatibility version 18.0.0, current version 18.5.0)
/opt/local/lib/libintl.8.dylib (compatibility version 10.0.0, current version 10.1.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)
/opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.1.0)
/System/Library/Frameworks/LDAP.framework/Versions/A/LDAP (compatibility version 1.0.0, current version 2.2.0)
/opt/local/lib/libssl.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/opt/local/lib/libcrypto.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)

这里的问题是我的文件夹/opt/local/甚至不存在。

如何修复丢失的链接？
我在哪里可以找到丢失的文件？（libidn.11.dylib，libintl.8.dylib，libssl.1.0.0.dylib，libcrypto.1.0.0.dylib和libz.1.dylib）？

其他信息：

我使用的是ruby 1.9.3和Mac OSX 10.8

听起来您还没有完全删除MacPorts及其curl。

如果您还没有，请按照http://guide.macports.org/chunked/installing.macports.uninstalling.html上的指南进行操作，具体如下：

$ sudo rm -rf \
    /opt/local \
    /Applications/DarwinPorts \
    /Applications/MacPorts \
    /Library/LaunchDaemons/org.macports.* \
    /Library/Receipts/DarwinPorts*.pkg \
    /Library/Receipts/MacPorts*.pkg \
    /Library/StartupItems/DarwinPortsStartup \
    /Library/Tcl/darwinports1.0 \
    /Library/Tcl/macports1.0 \
    ~/.macports

之后，您需要使用sudo rm /usr/local/bin/curl删除curl。

操作系统X中已包含

curl和libcurl，但/usr/local/bin之前/usr/bin位于您的路径中。因此，在某些时候，您可能已安装了一个新版本的curl，其中包含MacPorts，现在已经遗留下来。

因此，您需要完全清除curl中的/usr/local内容。这可能最终有点棘手，如果你没有安装Homebrew，那么在重新安装Homebrew之前完全清除Homebrew并手动清理/usr/local可能是个好主意。

最后，一旦curl消失，您将需要删除依赖于libcurl的gem并重新安装。

如果在卸载MacPorts之前使用MacPorts卸载curl，可能已经避免了所有这些，但我自己从未使用过MacPorts，因此不是100％使用MacPorts。

从MacPorts切换到Homebrew后，libcurl缺少库
