Answer 1

Abra el archivo /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

! version.startsWith (''iOS'') -> versión. incluye (''iOS'')

Answer 2

Arreglo temporal:

Paso 1 : Abra el archivo /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

Paso 2 : Cambiar una línea de código, a partir de esto:

if (!version.startsWith(''iOS'') && !version.startsWith(''tvOS'')) {
continue;
}

a esto:

if (!version.startsWith(''com.apple.CoreSimulator.SimRuntime.iOS'') && !version.startsWith(''com.apple.CoreSimulator.SimRuntime.tvOS'')) {
continue;
}

Paso 3 : ejecute react-native run-ios (puede que tenga que ejecutarlo dos veces, y no se olvide de matar a Metro Bundler [la consola que se ejecuta en segundo plano] si se está ejecutando desde su compilación anterior fallida)

El problema fue que después de una actualización de Xcode, los espacios de nombres del simulador se agregaron a la lista de versiones de los dispositivos. La compilación React Native no esperaba estos espacios de nombres, de ahí la ruptura de la compilación.

Answer 3

Con react-native-cli 2.0.1, es posible que solo desee cambiar el nombre de su simulador. Por defecto, Xcode nombrará algunos dispositivos en el formato <DeviceName> (<DeviceSize>) . Sin embargo, esta versión de la CLI interpreta cualquier cosa entre paréntesis como la versión de iOS.

Al intentar ejecutar un simulador llamado iPad Pro (10.5-inch) , pude hacerlo funcionar simplemente cambiando el nombre del simulador a iPad Pro [10.5-inch] .

Puede cambiar el nombre de los simuladores utilizando el menú Hardware -> Device -> Manage Devices... la aplicación Simulator y haciendo clic con el botón derecho en uno de sus simuladores (en Xcode 10.2.1)

Answer 4

Editado: copié la sección de dispositivos de su JSON de salida y lo /node_modules/react-native/local-cli/runIOS/runIOS.js en mi /node_modules/react-native/local-cli/runIOS/runIOS.js

function runOnSimulator(xcodeProject, args, scheme) {
return new Promise(resolve => {
try {
var simulators = {devices section of your json}; //Here
} catch (e) {
console.log("e", e);
throw new Error(''Could not parse the simulator list output'');
}
const selectedSimulator = findMatchingSimulator(simulators, args.simulator);
console.log("selected", selectedSimulator);
if (!selectedSimulator) {
throw new Error(`Could not find ${args.simulator} simulator`);
}
...

Y finalmente, dio el mismo error que el tuyo. Así que me di cuenta de que la versión de análisis de dispositivos diferentes. En tus dispositivos, la versión es;

"com.apple.CoreSimulator.SimRuntime.tvOS-12-1" //for tvOS
"com.apple.CoreSimulator.SimRuntime.iOS-12-1" // for iOS

pero en react-native verifica los valores de esta versión como este ( /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js );

// Making sure the version of the simulator is an iOS or tvOS (Removes Apple Watch, etc)
if (!version.startsWith(''iOS'') && !version.startsWith(''tvOS'')) {
continue;
}

Así reaccionar-nativo no puede reconocer.
Si cambiamos este código con esto;

// Making sure the version of the simulator is an iOS or tvOS (Removes Apple Watch, etc)
if (!version.startsWith(''com.apple.CoreSimulator.SimRuntime.iOS'') && !version.startsWith(''com.apple.CoreSimulator.SimRuntime.tvOS'')) {
continue;
}

El problema fue resuelto. Lo verifiqué con tus datos JSON en mi computadora y funcionó.

Answer 5

Me enfrenté al problema cuando actualicé Xcode. Todos los simuladores no estaban disponibles / desinstalados. Los estoy instalando de nuevo.

Answer 6

Mi problema fue que el simulador de iPhone X no estaba instalado

Puedes comprobar con qué simuladores están instalados.

 xcrun simctl list devices --json | grep iPhone

Entonces corre

react-native run-ios --simulator="iPhone Xs"

Answer 7

Para corregir este error, simplemente reinstale el proyecto usando npm

npm install

Luego mostrará una lista de advertencias, y para corregirlas use el siguiente comando:

npm audit fix

Esto debería solucionarlo todo y permitirle ejecutar el emulador de iOS.

Answer 8

Solo reinicia tu computadora y ejecuta el comando nuevamente.

Answer 9

después de actualizar a Xcode 11, xcrun devuelve verdadero o falso y no SÍ o NO como antes.

goto /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js y en

encontrar

if (
simulator.availability !== ''(available)'' &&
simulator.isAvailable !== ''YES''
) {
continue;
}

y cambiarlo a

if (
simulator.availability !== ''(available)'' &&
simulator.isAvailable !== true
) {
continue;
}

Answer 10

en mi caso, ejecuté el script: sed -i '''' ''s / startsWith / includes / g'' node_modules / react-native / local-cli / runIOS / findMatchingSimulator.js y funcionó. También es adecuado para personas que no pueden actualizar reactivo-nativo

Answer 11

si no se pudo encontrar, el simulador aún persiste después de reemplazar las siguientes líneas de código en runSimulator.js.

Ruta para runSimulator.js -> /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

if (!version.startsWith(''iOS'') && !version.startsWith(''tvOS'')) { continue; }

Con este

if ( !version.startsWith(''com.apple.CoreSimulator.SimRuntime.iOS'') && !version.startsWith(''com.apple.CoreSimulator.SimRuntime.tvOS'') ) { continue; }

comenta las siguientes líneas después de reemplazar

if ( simulator.availability !== ''(available)'' && simulator.isAvailable !== ''YES'' ) { continue; }

Lanzará iPhone simulador sin ningún problema.

y segundo enfoque después de actualizar a XCode 11

Xcode 11 xcrun devuelve verdadero o falso y no SÍ o NO para la propiedad isAvailable como antes. Puedes comprobar que usando el siguiente comando

xcrun simctl list devices --json

El comando anterior imprimirá todos los dispositivos disponibles como los siguientes

"com.apple.CoreSimulator.SimRuntime.iOS-12-2" : [
{
"state" : "Booted",
"isAvailable" : true,
"name" : "iPhone X",
"udid" : "E53748D1-628B-4A99-A419-4D7AE7CE4745"
}
]

Reemplace SÍ con verdadero en el siguiente código

if ( simulator.availability !== ''(available)'' && simulator.isAvailable !== ''YES'' ) { continue; }

Me gusta esto

if ( simulator.availability !== ''(available)'' && simulator.isAvailable !== true ) { continue; }
