这个命令解决了我的问题：

ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib

要么

ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

我在这里写了关于这个问题的要点。那里也有很多人分享他们的解决方案。

这听起来似乎很明显，但是如果命令不能逐字运行，请将版本更改为预期版本以及目录中最接近的版本。我的机器在期待第6版，我不得不版本7

ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib也可以是一个解决方案

ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib我认为您需要检查安装在的位置/usr/local/opt/readline/lib，然后将其链接到libreadline.6.dylib。就我而言，我需要将6链接到8。在答案中@Zulhilmi将6链接到

很棒。权宜而又保守。没有符号链接可以忘记，也没有安装可能引起其他问题的安装。

我有同样的潜在问题，在Mac OSX更新后也发生了。我的问题使用psql表现出来：

>> psql --help

dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib
  Referenced from: /usr/local/bin/psql
  Reason: image not found

好的，所以这告诉我期望libreadline.7.dylib在中/usr/local/opt/readline/lib。当我浏览该目录时，我可以看到libreadline.8.0.dylib：

>> ls -l /usr/local/opt/readline/lib

total 1448
 libhistory.8.0.dylib
 libhistory.8.dylib -> libhistory.8.0.dylib
 libhistory.a
 libhistory.dylib -> libhistory.8.0.dylib
 libreadline.8.0.dylib
 libreadline.8.dylib -> libreadline.8.0.dylib
 libreadline.a
 libreadline.dylib -> libreadline.8.0.dylib

我假设libreadline.7.dylib使用符号链接进行仿真libreadline.8.0.dylib可以解决我的问题：

>> ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

这使我的电话psql再次工作，但一开始并没有解决问题的开始方式。

我再次安装了相同版本的红宝石。然后错误消息消失了。我使用macbook和自制软件。

$ rbenv install 2.3.8

这似乎是正确的方法（比假设库的v8与v7兼容更好）。对于rvm：rvm reinstall ruby-2.6.2

只需使用自制软件更新的readline重新编译红宝石版本，它的工作原理就像一个魅力。

我遇到了相同类型的问题，但这是由于我的awk与gawk相关联导致使用错误的lib

在我的情况下，在MacOS迁移后已安装readline，但未链接。此命令修复了该问题：

只需重新安装ruby 2.3.0即可在macOS上解决我的问题，我使用rbenv rbenv install 2.3.0做到了
