不久前我删除了 Macports，所以现在我使用 Homebrew。现在我正在尝试使用依赖于 multicurl 的 typhoeus ruby​​ gem。

当我尝试执行我的 ruby​​script 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。

当我执行时，$ otool -L /usr/local/bin/curl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）？

附加信息：

  • 我正在使用 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，您将需要遵循http://guide.macports.org/chunked/installing.macports.uninstalling.html上的指南，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，您将需要使用sudo rm /usr/local/bin/curl.

curl并且libcurl已经包含在 OS X 中，但/usr/local/bin在/usr/bin. 因此，在某些时候，您可能安装了一个新版本的curlMacPorts，而现在还剩下。

因此，您将需要完全curl清除/usr/local. 这最终可能会有点棘手，如果您没有安装很多 Homebrew，那么/usr/local在重新安装 Homebrew 之前完全清除 Homebrew 并手动清理可能是个好主意。

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

curl如果在卸载 MacPorts 之前使用 MacPorts 卸载所有这些可能都可以避免，但我自己从未使用过 MacPorts，所以不是 100%。
