问题：

dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.8.dylib
  Referenced from: /usr/local/bin/gpg
  Reason: image not found
Abort trap: 6

解决：

不知什么原因 /usr/local/opt 内的readline 没有了
将 readline 重新指向 /usr/local/opt 目录

ln -s /usr/local/Cellar/readline/8.0.4/ /usr/local/opt/readline

详细步骤：

1. 检查文件链接信息

$ otool -L /usr/local/bin/gpg

/usr/local/bin/gpg:
    /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.11)
    /usr/lib/libbz2.1.0.dylib (compatibility version 1.0.0, current version 1.0.5)
    /usr/local/opt/gettext/lib/libintl.8.dylib (compatibility version 11.0.0, current version 11.0.0)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1675.129.0)
    /usr/lib/libsqlite3.dylib (compatibility version 9.0.0, current version 308.4.0)
    /usr/local/opt/libgcrypt/lib/libgcrypt.20.dylib (compatibility version 23.0.0, current version 23.6.0)
    /usr/local/opt/libgpg-error/lib/libgpg-error.0.dylib (compatibility version 31.0.0, current version 31.0.0)
    /usr/local/opt/readline/lib/libreadline.8.dylib (compatibility version 8.0.0, current version 8.0.0)
    /usr/local/opt/libassuan/lib/libassuan.0.dylib (compatibility version 9.0.0, current version 9.3.0)
    /usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1281.100.1)

/usr/local/opt/readline/lib/libreadline.8.dylib (compatibility version 8.0.0, current version 8.0.0)

2. 检查路径目录内是否存在这个库（这里没有返回结果，也就是不存在）

$ ll /usr/local/opt/ | grep -i "readline"

3. 去 Cellar 找找 libreadline.8.dylib 的真实位置

$ ls /usr/local/Cellar | grep -i "readline"
readline


$ /usr/local/Cellar/readline/8.0.4/lib

-r--r--r--  1 ruiliang  staff   44512  2 22  2020 libhistory.8.0.dylib

drwxr-xr-x  3 ruiliang  staff      96  2 22  2020 pkgconfig

4. 建立软连接

$ ln -s /usr/local/Cellar/readline/8.0.4/ /usr/local/opt/readline
