我已经通过自制软件安装了readline. 我想继续使用rbenv而不是rvm.

I have installed readline via homebrew. I'd like to keep using rbenv instead of rvm.

感谢您阅读我的问题.

推荐答案

我最近在自制软件和libreadline.7.x.dylib/libreadline.6.x.dylib中遇到了相同的问题

I had the same issue recently with homebrew and libreadline.7.x.dylib / libreadline.6.x.dylib

我通过运行解决了该问题:

I solved it by running:

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