Como instalar Expo (React Native)
Raw
HowInstallExpo.md

Instalación Expo para React Native

Instalando Expo

Primero instalamos con npm explo-cli y exp (debemos de tener Node.js y npm instalados)

npm install -g expo-cli exp

Después creamos nuestra zona de trabajo, le decimos como se quiere llamar la carpeta:

expo init nombreApp

Una vez que tengamos la carpeta nos metemos dentro:

cd nombreApp

Una vez dentro ya arrancamos Expo:

expo start

Ya podremos utilizar un emulador de Android o iOS o con la app de Expo ver la app en el móvil

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:

expo : El término 'expo' no se reconoce como nombre de un cmdlet, función, archivo de script o programa ejecutable. Compruebe si escribió correctamente el nombre o, si incluyó una ruta de acceso, compruebe que dicha ruta es correcta e inténtelo de nuevo.

**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**

Hola! tengo un problema que solo me ocurre en Ubuntu (20.04.5 LTS). Al hacer npm start el linter encuentra un error de sintaxis en módulo de expo, algo que no me ocurre cuando trabajo el repo en windows.
