ruby - Cómo obtener soporte de Readline en IRB usando RVM en Ubuntu 11.10

libreadline

Question

He intentado todo lo que se me ocurre para hacer que esto funcione, en vano, así que aquí estoy solicitando sugerencias sobre cómo depurar.

En primer lugar, ejecutando Ubuntu 11.10

Rvm instalado:

$ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

Línea de lectura instalada usando apt-get:

$ sudo apt-get install libreadline-dev

Verifique la instalación readline:

$ dpkg --get-selections | grep readline
lib64readline-gplv2-dev install
lib64readline5 install
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install

Instalar ruby, con soporte de lectura?

$ rvm install 1.9.2 --with-readline-dir=/usr

Aquí está la versión rvm:

$ rvm --version
rvm 1.9.2 by Wayne E. Seguin ([email protected]) [https://rvm.beginrescueend.com/]

Vamos a probar el caparazón de rubí:

$ irb
1.9.2 :001 > puts "add history"
add history
=> nil
1.9.2 :002 > ^[[A^[[A^[[A^[[A^[[A <------ PRESS UP ARROW DOES THIS

No, está bien, así que si no va a funcionar con la versión de lectura de ubuntu ??? intentemos con la versión propia de rvm de readline:

$ rvm pkg install readline

Ok, hay un error allí, echemos un vistazo:

Y como se esperaba, irb no funciona con readline:

Por lo tanto, para concluir, estaría muy agradecido si una chispa brillante pudiera sugerir cómo puedo depurar esta situación y resolverla.

ps - Sí, tengo "Google" este problema hasta la muerte ...

Answer 1

Desafortunadamente, ninguno de estos funcionó para mí. Terminé usando la solución rápida de http://beginrescueend.com/packages/readline/

Eso resolvió mi problema.

Answer 2

Esto resolvió mi problema para rvm con Ruby 1.9.3

gem install rb-readline

Answer 3

Estos pasos arreglaron mi problema (en un Lubuntu 12.04) después de compilar ruby ​​y obtener continuamente el error de "error de lectura de compilación" cada vez que ejecuté:

sudo aptitude install build-essential openssl libreadline6 /
libreadline6-dev curl git-core zlib1g zlib1g-dev /
libssl-dev libyaml-dev libsqlite3-dev sqlite3 /
libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev /
automake libtool bison subversion
rvm pkg uninstall readline
rvm remove 1.9.3
rvm install 1.9.3

Answer 4

Luché con este mismo problema con Ubuntu 11.10.

En mi caso, readline aparentemente compilaría correctamente si usaba lo siguiente:

$ rvm --skip-autoreconf pkg install readline

como se indica en la parte inferior de http://beginrescueend.com/packages/readline/

Sin embargo, cuando invocaba irb, obtenía el error normal "No se puede requerir readline"

Finalmente, basado en la línea de comando de Shane, invoqué lo siguiente:

$ rvm install 1.9.3 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path

en lugar del comando mencionado en http://beginrescueend.com/packages/readline/

$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

En mi caso, la versión 1.9.3 era lo que quería. Y finalmente, Irb creó una línea de lectura funcional.

Gracias a todos aquí por señalarme en la dirección correcta.

Answer 5

Mi configuración es ubuntu 11.10, RVM 1.10.2, ruby ​​1.9.3.

Este problema de readline generaba errores al ejecutar irb y evitaba el funcionamiento de la consola de rails debido al error:

''require'': no ​​se puede cargar dicho archivo - readline (LoadError)

La solución que funcionó para mí fue la descrita por Bryan Larsen, es decir,

NO instale pkg readline, con o sin --skip-autoreconf

Haga la instalación de apt-get que los requisitos de rvm le dicen que haga, luego

rvm --skip-autoreconf pkg uninstall readline

rvm eliminar 1.9.3

rvm instalar 1.9.3

Thx por el consejo Bryan.

Answer 6

Ok, entonces esto puede parecer bastante obvio, bueno, siempre es cuando sabes la respuesta:

Dejé de usar RVM y cambié a rbenv, ¡lo que estoy muy contento de haber hecho!

sudo apt-get install libreadline-gplv2-dev
CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline --with-openssl-dir=/usr/local" rbenv-install 1.9.2-p290

Esto se instaló sin error, y aún no estoy convencido de que necesite el paquete gplv2 ya que tengo instalado libreadline6-dev. Sin embargo, STILL no resolvió mi problema. Eliminó RVM de la ecuación y me mostró que, a pesar de mis mejores esfuerzos, el shell IRB se negaba a usar readline.

La respuesta vino de leer esta gran guía:

RubyTools.pdf

Dentro de mi archivo ~ / .irbrc encontré:

IRB.conf[:USE_READLINE] = false

Una actualización rápida para:

IRB.conf[:USE_READLINE] = true

¡Y estoy cocinando con gasolina!

Gracias por todas las excelentes respuestas y sugerencias, realmente aprecio tu tiempo.

Puedes ver que funciona bien para mí.

1 - no olvides instalar libedit-dev

# dpkg --get-selections| egrep ''(readline|libedit)''
libedit-dev install # <= BSD PACKAGE, not GNU, but... it is work fine to me
libedit2 install # the same story as previous
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install

2 - desinstalación de pkg readline

$ rvm pkg uninstall readline

3 - vaya a $ rvm_path / src / ruby ​​- # {version} / ext / readline y haga

$ ruby extconf.rb; make; make install

4 - olvídate del dolor de cabeza

Answer 8

Para mí, todo salió de la caja con la última versión de rvm. Mis pasos

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

de acuerdo con los rvm requirements :

apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
rvm install 1.9.3
rvm

Answer 9

Puede probar un workarround instalando el paquete libreadline5-dev . Creo que la libreadline6-dev no está funcionando en este momento.

Answer 10

Tuve el mismo problema pero estoy en 11.04 y al leer el enlace me diste github.com/wayneeseguin/rvm/issues/553 y de la información en peplins comento que eliminé la llamada de autoreconf que se agregó aquí.
https://github.com/wayneeseguin/rvm/commit/94c301d y ahora compila readline sin ningún error. Añadí de nuevo en la llamada de autorreconf después de haber compilado readline antes de instalar Ruby nuevamente.

Así que así es como lo hice funcionar:

edite ~ / .rvm / scripts / functions / pkg y elimine lo siguiente:

if [[ "${rvm_skip_autoreconf_flag:-0}" == 0 ]] &&
which autoreconf >/dev/null 2>&1 &&
which libtoolize >/dev/null 2>&1 &&
[[ -f configure.ac || -f configure.in ]]
then
__rvm_run "$package/autoreconf" /
"autoreconf -is --force" /
"Prepare $package in $rvm_src_path/$package-$version."
fi

Compila readline y quita ruby ​​(utilicé el comando ree_dependencies pero no estoy seguro de que sea necesario):

rvm pkg install ree_dependencies
rvm remove 1.9.2

deshace tu eliminación a ~ / .rvm / scripts / functions / pkg
Luego instalé 1.9.2 con este comando (de nuevo es de la instalación de ree, que no estoy seguro es necesario pero esto es lo que usé)

rvm install 1.9.2 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path

y ahora todo parece funcionar como debería, espero que ayude a alguien.

Answer 11

Ubuntu 12.04 aquí: las respuestas aquí ayudaron, pero también fueron engañosas.

Si está utilizando Ubuntu 12.04, NO instale pkg readline, con o sin --skip-autoreconf. Después de que hayas hecho eso, readline o zlib se romperán no importa qué combinación de switches le des a la instalación de rvm 1.9.3.

Para que funcione, haga la instalación de apt-get que los rvm requirements le dicen que haga, haga una línea de base de datos para la pkg uninstall readline y luego haga un simple rvm remove 1.9.3; rvm install 1.9.3 rvm remove 1.9.3; rvm install 1.9.3

Answer 12

Si está utilizando Bundler , lo siguiente podría ayudar:

echo "gem ''rb-readline''" >> Gemfile
bundle install
