尝试在 win10 上安装 gpg2。按照此线程底部的答案操作；如何在 cygwin 上安装 gpg？目前缺失
但是在尝试软链接它们时遇到了问题；
当我检查新的下载时，我有“正确”的版本；
$ /c/Program\ Files\ \(x86\)/GnuPG/bin/gpg.exe --version
gpg (GnuPG) 2.1.21
libgcrypt 1.7.6

两者都喜欢；
$ ln -s /c/Program\ Files\ \(x86\)/GnuPG/bin/gpg.exe /usr/bin/gpg2
ln: failed to create symbolic link '/usr/bin/gpg2': File exists
$ ln -s /c/Program\ Files\ \(x64\)/GnuPG/bin/gpg-agent.exe /usr/bin/gpg-agent
ln: failed to create symbolic link '/usr/bin/gpg-agent': File exists
我不明白为什么我会收到此消息；
$ gpg2
C:/msys64/usr/bin/gpg2: error while loading shared libraries: ?: cannot open
shared object file: No such file or directory
我这样做的原因是；
$ \curl -sSL https://get.rvm.io | bash -s stable
ERROR: Could not find GNU compatible version of 'tar' command, make sure it's available first before continuing installation.
如果有其他方法可以安装 RVM，我会很高兴知道
答案1
我正在尝试在 win10 上安装 gpg2
无需使用您提供的链接中的复杂说明来安装 gpg2。
这gpg2软件包可通过常规 Cygwin 安装程序获得。如果您使用此安装程序安装，它将被正确配置。
运行安装程序
继续，直到到达“选择套餐”屏幕
将“视图”设置为“完整”
将“搜索”设置为“gnupg2”
点击第一个“Skip”（会变成版本号2.1.21-1）
点击“下一步”进行安装
答案2
据 David 报道，GNU Privacy Guard 版本 2 可在Cygwin
https://www.cygwin.com/ml/cygwin-announce/2017-06/msg00080.html
作为 1 的最新版本
https://sourceware.org/ml/cygwin-announce/2016-08/msg00109.html
两个版本并行共存。
