Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib

Question

When I try running rails console I get this error:

/Users/TuzsNewMacBook/.rvm/gems/ruby-2.3.7/gems/bootsnap-1.3.2/lib/bootsnap/load_path_cache/core_         


        

Answer 1

Background: This has happened when I tried to install tig, but I think this is a common issue that you may have that you need to manually link the installed software into the right path that another software wants.

If you can not find readline installed on your Mac, you should run

brew install readline

After you installed deadline, brew will ask you to link it. But actually you can not link by running

brew link readline

Even you can not link by running

sudo brew link readline

Mac OS will warn you this is extremely dangerous and stop you to do.

The Latest version of readline is version 8, so you will see the error message like

Library not loaded: /usr/local/opt/readline/lib/libreadline.8.dylib

The brew installed deadline at

/usr/local/Cellar/readline/8.0.4

So you have to manually link it to the place that your software wants by using command ls

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

Enjoy!
