rails c not working in rails 5

Question

On using the command in terminal inside a rails 5 application

rails c

the error thrown is given bellow. I have no idea what this means in a si

Answer 1

As a general approach if this error occurred due to updating readline with homebrew

New version can be found by reading the output of brew install readline

My output: readline 8.0.0 is already installed and up-to-date

Old version can be found by load error

My error (Note the 7): Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib (LoadError)

ln -s new_version/path/to/readline original_version/path/to/readline

In my case my command was

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