What should I do now?
This command fix my problem:
ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib
OR
ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib
I wrote a Gist about this problem here. There are many people sharing their solutions there too.
Add this gem to your Gemfile and run bundle install
:
gem 'rb-readline'
I had the same underlying issue, which also occurred after a Mac OSX update. My problem manifested using psql:
>> psql --help
dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib
Referenced from: /usr/local/bin/psql
Reason: image not found
OK, so this is telling me that it's expecting libreadline.7.dylib
in /usr/local/opt/readline/lib
. When I browse that directory, I can see I have 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
I made the assumption that emulating libreadline.7.dylib
by using symlinking to libreadline.8.0.dylib
could resolve my problem:
>> ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib
Which makes my call to psql
work again, but doesn't address how the problem started in the first place.
