非特权用户 dyld 的 OSX curl 错误：库未加载

Question

我的 MAC 操作系统是 Yosemite 10.10，它有一个旧版本的 curl。我已经安装了 Xcode 和 Xcode 命令行工具。

I run cURL with the "sudo" command as  “sudo curl”:
    sudo curl
    Password:
    curl: try 'curl --help' or 'curl --manual' for more information

However, when I run curl under the common user in the the terminal, it failed as follows:

  dyld: Library not loaded: /usr/lib/libcurl.4.dylib
  Referenced from: /usr/bin/curl
  Reason: Incompatible library version: curl requires version 7.0.0 or later, but libcurl.4.dylib provides version 5.0.0
  Trace/BPT trap: 5


  I also downloaded the curl version of 7.43, and installed in /usr/local/bin.

  —  "which curl”  shows “/usr/local/bin/curl” 
  —  otool shows:
     otool -L /usr/local/bin/curl
     /usr/local/bin/curl:
     /usr/local/lib/libcurl.4.dylib (compatibility version 8.0.0, current version 8.0.0)
     /usr/lib/libssl.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
     /usr/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
     /System/Library/Frameworks/LDAP.framework/Versions/A/LDAP (compatibility version 1.0.0, current version 2.4.0)
     /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
      /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

   otool -L /usr/local/lib/libcurl.4.dylib 
    /usr/local/lib/libcurl.4.dylib:
    /usr/local/lib/libcurl.4.dylib (compatibility version 8.0.0, current version 8.0.0)
    /usr/lib/libssl.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
    /usr/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
     /System/Library/Frameworks/LDAP.framework/Versions/A/LDAP (compatibility version 1.0.0, current version 2.4.0)
     /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
     /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

但是，curl 仍然可以使用“sudo”，但对于普通用户却失败了，即，

  dyld: Library not loaded: /usr/local/lib/libcurl.4.dylib
  Referenced from: /usr/local/bin/curl
  Reason: Incompatible library version: curl requires version 8.0.0 or later, but libcurl.4.dylib provides version 5.0.0
  Trace/BPT trap: 5

同时，之前的解决方案（尝试使用自制软件安装 curl，为 libcurl.4.dylib 获取“不兼容的库版本”）对我的情况不起作用。

实际上，似乎调用 libcurl 的命令无法使用相同的信息运行，例如：

--MacPorts：

  [user @MBK ~]$port

  dlopen(/opt/local/libexec/macports/lib/pextlib1.0/Pextlib.dylib, 6): Library not   loaded: /usr/lib/libcurl.4.dylib
   Referenced from: /opt/local/libexec/macports/lib/pextlib1.0/Pextlib.dylib
   Reason: Incompatible library version: Pextlib.dylib requires version 7.0.0 or later, but libcurl.4.dylib provides version 5.0.0
    while executing "load /opt/local/libexec/macports/lib/pextlib1.0/Pextlib.dylib"
    ("package ifneeded Pextlib 1.0" script)
    invoked from within "package require Pextlib 1.0"
    (file "/opt/local/bin/port" line 47)

- 网卡：

 [user@MBK ~]$ncdump 

  dyld: Library not loaded: /opt/local/lib/libcurl.4.dylib
   Referenced from: /opt/local/bin/ncdump
   Reason: Incompatible library version: ncdump requires version 8.0.0 or later, but libcurl.4.dylib provides version 5.0.0
  Trace/BPT trap: 5

同样，带有“sudo”的命令有效。

要么你有两个问题，要么一个讨厌的问题，要找出哪一个类型的命令，sudo sh -c 'type curl';type curl如果两种类型的命令显示相同的文件，你会遇到困难，但可能你有两个更简单的问题：curl安装了两次，并且你的动态链接器配置错误。
