如何在cygwin上安装gpg2？

试图在win10上安装gpg2。在这个帖子上跟着底部回答; 如何在cygwin上安装gpg？目前它不见了

但在尝试软链接时遇到了问题;

检查新下载时，我有“正确”的版本;

$ /c/Program\ Files\ \(x86\)/GnuPG/bin/gpg.exe --version

喜欢两个;

$ 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

我不明白为什么我得到这个消息;

$ gpg2
C:/msys64/usr/bin/gpg2: error while loading shared libraries: ?: cannot open 
shared object file: No such file or directory

我这样做是因为;

$ \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.

如果有任何其他方法来安装RVM，我会很高兴知道

你为什么不通过Cygwin安装它？ gnupg2-2.1.21-1 - gnupg2：用于安全通信和数据存储的GNU工具可从Cygwin获得

— DavidPostill

我做到了，但他们的设置只有gpg 1.4; imagebin.ca/v/3SfnlmLOcfp9

现在研究如何安装单个软件包，在Cygwin上不熟悉它。

— Eirik Kvalheim

我找到了apt-cyg，但后来我必须安装 wget的 ，柏油，呆子和 bzip2的 ，然后它更容易解决问题，不是吗？

— Eirik Kvalheim

不，他们没有。看我的回答。

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安装gpg2。

该 gpg2 包可以通过正常的Cygwin安装程序获得。如果使用它安装它将正确配置。

运行安装程序
继续，直到进入“选择包”屏幕
将“查看”设置为“完整”
将“搜索”设置为“gnupg2”
单击第一个“跳过”（它将更改为版本号2.1.21-1）
单击“下一步”进行安装
