Primero instalamos con npm explo-cli y exp (debemos de tener Node.js y npm instalados)
npm install -g expo-cli expDespués creamos nuestra zona de trabajo, le decimos como se quiere llamar la carpeta:
expo init nombreAppUna vez que tengamos la carpeta nos metemos dentro:
cd nombreAppUna vez dentro ya arrancamos Expo:
expo startYa podremos utilizar un emulador de Android o iOS o con la app de Expo ver la app en el móvil
Haz un node -v y mira que versión te pinta en pantalla. Si supera la 15 o si es menor de la 10.13.0, te recomiendo que instales nvm, así puedes cambiar de versiones rápido.
De todas maneras en la web de Expo pone bien claro esto (https://expo.io/learn):
Node.js: In order to install Expo CLI you will need to have Node.js (we recommend the latest stable version- but the maintenance and active LTS releases will also work) installed on your computer. Download the recommended version of Node.js.
Yo te recomendaría tener la última LTS, al menos es estable y está libre de bugs.
Espero haberte ayudado 👍
Gracias Bro
que tal, al escribir el comando ( expo init 'nombre app' )me tira este error en Ubuntu.
Orden «expo» no encontrada. Quizá quiso decir:
Mira si tienes bien instalado en global el expo:
npm install expo-cli --global
O sino mira en stackoverflow:
https://stackoverflow.com/questions/54248522/expo-cli-is-installed-but-bash-expo-command-not-found
Buenas, ejecuto el comando:
npm install -g expo-cli exp
Y me da error de conección..
me podras dar ayuda de como resolverlo? Gracias de antemano.

Alguien sabe porque a el momento de estar en desarrollo me falla la compilación. Me aparece el siguiente error
Failed building JavaScript bundle.
Cannot read property 'reduce' of undefined
Failed building JavaScript bundle. Cannot read property 'reduce' of undefined
Y tambien este mensaje de alerta
Your project is in SDK version >= 33.0.0, but the expo package version seems to be older.
Buenas noches!
Después de instalar expo trato de crear un proyecto y me tirá un error.

@Estebanpz aunque sea tarde, creo que el problema está en el builder, estás usando por ejemplo reducers y no lo entiende.
@germanmauro no sé si lo que te dice es que tienes problemas con npm, mira que esté bien instalado o el propio expo no está bien estalado, ya que no encuentra el comando.
@mrcodedev Si, acabo de instalar expo npm install -g expo-cli exp, tambien actualice npm
Si escribes: expo whoami Te funciona esto???. De todas maneras esto lo escribí hace bastante, la docu oficial actual es esta: https://docs.expo.io/get-started/installation/
@mrcodedev No, tampoco funciona
Hola, una pregunta.
Cada vez que quiera crear un proyecto nuevo en React Native, tengo que ejecutar este comando: npm install -g expo-cli exp ?
¿No basta con hacerlo la primera vez?
Gracias

En teoría sólo debería ser la primera vez ya que lo instalas como dependencia global y ya está :\
odio expo
Yo cuando estaba con él también, a una mala mírate Capacitor, por si te gusta más el desarrollo con esa herramienta.
Me tira el siguiente error al intentar iniciar. Osea, instala bien, pero a su vez no. No me deja iniciar, ni chequear la version ni hacer nada:

**Edit:
Lo solucioné instalando la última versión de node con nvm, después actualicé npm. Eliminé reinstalé node modules en el proyecto.
nvm install 19.6.1 && nvm use 19.6.1 && npm install -g npm@latest
en el proyecto
rm -r node_modules && npm install**
