¿Qué debería hacer ahora?

Answer 1

Agregue esta gema a su Gemfile y ejecute la bundle install :

gem ''rb-readline''

Answer 2

En mi caso, readline se instaló pero no se vinculó después de una migración de MacOS. Este comando lo arregló:

brew link --force readline

Answer 3

Estaba teniendo el mismo tipo de problema, pero se debió al hecho de que mi awk estaba vinculado a gawk, lo que me llevó a usar la biblioteca incorrecta

esto funcionó para mí

brew unlink gawk

Answer 4

Este comando soluciona mi problema:

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

O

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

Escribí un Gist sobre este problema here . Hay muchas personas que comparten sus soluciones allí también.

Answer 5

Instalé el rubí de la misma versión nuevamente. Entonces el mensaje de error se ha ido ahora. Yo uso macbook y homebrew.

$ rbenv install 2.3.8
rbenv: /Users/klee/.rbenv/versions/2.3.8 already exists
continue with installation? (y/N) y
ruby-build: use openssl from homebrew
Downloading ruby-2.3.8.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.8.tar.bz2
Installing ruby-2.3.8...
ruby-build: use readline from homebrew
Installed ruby-2.3.8 to /Users/klee/.rbenv/versions/2.3.8

Answer 6

Solo recompilé la versión ruby ​​usando readline actualizado de homebrew y funciona de maravilla.

rbenv install $(rbenv version-name)

Answer 7

Tuve el mismo problema subyacente, que también ocurrió después de una actualización de Mac OSX. Mi problema se manifestó usando 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, entonces esto me está diciendo que espera libreadline.7.dylib en /usr/local/opt/readline/lib . Cuando busco en ese directorio, puedo ver que tengo 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

libreadline.7.dylib que emular libreadline.7.dylib usando symlinking a libreadline.8.0.dylib podría resolver mi problema:

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

Lo que hace que mi llamada a psql funcione nuevamente, pero no aborda cómo comenzó el problema en primer lugar.

Answer 8

Tuve el mismo problema, lo que me ayudó fue

parada de primavera

Answer 9

simplemente reinstalar ruby ​​2.3.0 solucionó mi problema en macos que uso rbenv rbenv install 2.3.0 hizo el truco
