没有cygXmu-6.dll，Cygwin xclip将失败

试图安装以管理员身份运行的xclip，但出现以下问题：

$ apt-cyg install xclip Installing xclip xclip-0.12-2.tar.xz: OK Unpacking... Package xclip requires the following packages, installing: bash coreutils cygwin gzip libX11_6 libXmu6 tar Package bash is already installed, skipping Package coreutils is already installed, skipping Package cygwin is already installed, skipping Package gzip is already installed, skipping Package libX11_6 is already installed, skipping Package libXmu6 is already installed, skipping Package tar is already installed, skipping Package xclip installed Tommy@Tommy-PC ~ $ xclip C:/opt/cygwin64/bin/xclip.exe: error while loading shared libraries: cygXmu-6.dll: cannot open shared object file: No such file or directory 因此，我删除了所有X11库并尝试重新安装。但这就产生了一个更没有帮助的错误：

也许我可以尝试从源代码处编译或使用Cygwin安装程序？

安装软件包的标准方法是使用Cygwin安装程序。 apt cyg可能很方便，但它不是一个官方软件包

验证软件包安装的标准方法是使用cygcheck

$ cygcheck -c libX11_6
Cygwin Package Information
Package              Version        Status
libX11_6             1.6.5-1        OK

如果我们模拟包装的损坏

$ mv /usr/bin/cygX11-6.dll /usr/bin/cygX11-6.dll.tmp

$ cygcheck -cv libX11_6
Cygwin Package Information
Last downloaded files to: e:\downloads\cygwin_cache
Last downloaded files from: http://mirrors.kernel.org/sourceware/cygwin/

Package              Version        Status
Missing file: /usr/bin/cygX11-6.dll from package libX11_6
libX11_6             1.6.5-1        Incomplete

您还可以使用cygcheck dep包来查询依赖项，例如：

$ cygcheck-dep -r xwinclip
# /usr/bin/cygcheck-dep:
 xwinclip: requires ( cygwin libX11_6 libXfixes3 )

使用canonical来表示正确的用法很有趣。但是停止使用apt cyg的真正原因是开发者之间的争吵导致其开发停止。我使用它是因为apt cyg不是官方的cygwin包，所以cygwin项目的相关人员不支持它。你是对的。它比setup.exe更容易使用，但生活往往因其他人的大小战争而变得复杂。
