最佳答案

编辑: 我复制了输出 JSON 的设备部分，并嵌入到我自己的 /node_modules/react-native/local-cli/runIOS/runIOS.js中

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`);
}
...

最后，它出现了和你一样的错误。所以我发现解析设备的版本不同。在您的设备中，版本是;

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

但在反应-本机检查这个版本的值如下(/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;
}

所以反应本地不能识别。
如果我们用这个改变这个代码

// 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;
}

这个问题已经解决了。我用我电脑里的 JSON 数据检查了一下，它工作了。

要修复此错误，只需使用 npm 重新安装项目和节点模块

npm install

然后，它将显示一个警告列表，并使用以下命令修复它们:

npm audit fix

这将修复所有问题，并允许您运行 iOS 模拟器 react-native run-ios

小开

临时固定装置:

步骤1 : 打开文件 /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

步骤2 : 从这里更改一行代码:

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

回到这里:

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

步骤3 : 运行 react-native run-ios(可能需要运行两次，如果 Metro Bundler (在后台运行的控制台)运行的是之前不成功的版本，不要忘记关闭它!)

问题是，在更新 Xcode 之后，模拟器名称空间被添加到设备的版本列表中。反应本机构建没有预料到这些名称空间-因此构建中断。

小开

打开文件/node _ module/response-national/local-cli/runIOS/findMatchingSimulator.js

Version. StartsWith (‘ iOS’)-> ! version. 包括(‘ iOS’)

小开

在我的案例中，我运行脚本: Sed-i”的/startsWith/include/g’node _ module/response-national/local-cli/runIOS/findMatchingSimulator.js 成功了。也适用于那些不能更新本地反应的人

小开

在更新到 Xcode 11之后，xcrun 返回 true 或 false，而不是像以前那样返回 YES 或 NO。

进入 /node _ module/response-national/local-cli/runIOS/findMatchingSimulator.js

找到

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

然后改成

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

小开

在代替了 runSimulator.js 中的以下代码行之后，如果找不到模拟器，模拟器仍然存在。

RunSimulator.js-> 的路径 /node _ module/response-national/local-cli/runIOS/findMatchingSimulator.js

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

用这个

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

置换后的注释

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

它将毫无问题地启动 iPhone 模拟器。

和更新到 XCode11后的第二种方法

对于可用属性，Xcode 11 xcrun 返回 true 或 false，而不是 YES 或 NO，如前所述。您可以使用以下命令检查这一点

xcrun simctl list devices --json

上面的命令将打印所有可用的设备 ，如下所示

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

在以下代码中用没错替换 YES

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

像这样

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

小开

我的问题是没有安装 iPhone X 模拟器

您可以检查安装了哪些模拟器

xcrun simctl list devices | grep iPhone | grep -v unavailable | cut -d'(' -f1

那就快跑

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

小开

使用 response-national-cli 2.0.1，您可能只需要重命名您的模拟器。默认情况下，Xcode 将以 <DeviceName> (<DeviceSize>)格式命名某些设备。然而，这个版本的 CLI 将括号中的任何内容解释为 iOS 版本。

当试图运行一个名为 iPad Pro (10.5-inch)的模拟器时，我能够通过简单地将模拟器重命名为 iPad Pro [10.5-inch]来让它运行。

您可以通过使用 Simulator 应用程序的 Hardware-> Device-> Manage Devices...菜单来重命名模拟器，然后右键单击其中一个模拟器(在 Xcode 10.2.1中)

小开

我在更新 Xcode 时遇到了这个问题。所有的模拟器都不可用/没有安装。我正在重新安装它们。

小开

只要重新启动计算机，再次运行命令即可。

我每次更新 Xcode 都会遇到同样的问题。
我运行以下命令:

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

然后再运行 react-native run-ios。

问题

如果你用最新的 Xcode (11)尝试一下，就会发现没有 iPhone X！

运行模拟器本身，在顶部菜单中，查看硬件，设备，iOS 13.0。你会看到:

IPhone 8
IPhone 8 Plus
IPhone XS
IPhone XS Max
IPhone XR
还有一些 iPad

当执行 run-ios时，response-national 被设计为与请求的设备匹配。

内部硬编码的默认值是 iPhoneX。

试图与请求的设备匹配的函数位于:

/node_modules/@react-native-community/cli-platform-ios/build/commands/runIOS/findMatchingSimulator.js

这个功能的设计，使您可以给它一个设备，和一个可选的版本号。

如果找不到给定的设备和版本，默认情况下，它将使用列表中的第一个设备返回匹配。

但是... 实际上，第一个设备是一个手表，任何手表都被排除在匹配之外，所以这个函数将返回 null。

解决方案1-使用现有的 Xcode 设备

首先运行 Simulator，如上所述，并记录下你想要哪个 iPhone 或 iPad。

然后将这个名称作为可选参数传递给 run-ios 命令行命令，如下所示:

react-native run-ios --simulator="iPhone 8"

解决方案2-添加新的 Xcode iOS 设备

根据 Xcode 11发行说明:

”默认情况下，Xcode 不再创建所有可用的 iOS 模拟器设备。取而代之的是创建一组最常用的设备。要创建其他设备ーー或一个设备的多个实例ーー，请打开“设备”窗口，选择“模拟器”，单击“ +”按钮，输入名称，然后选择相关的设备类型和操作系统版本。在 Terminal 中，执行 xcrun simctl create 命令，例如 xcrun simctl create“ My iPhone 7”“ iPhone 7”iOS13.0。(49428617)”

在 Xcode，你需要添加一个名为“ iphonex”的新设备。

我还在这里回答: 反应本地问题 # 2328

很容易解决。

Xcode-> 偏好设置-> 组件安装 ios 12.2模拟器

小开

您的机器上没有 iPhoneX 模拟器，很可能是因为您更新了 Xcode。您可以简单地传递可用模拟器的名称，如下所示:

react-native run-ios --simulator="iPhone 11"

为了检查可用的模拟器，您可以打开 Xcode 并检查设备列表，如下所示:

我也没有在 Xcode 上安装 iPhone X 作为模拟器。我所要做的就是在 Xcode 添加 iphonex 作为一个新的模拟器，一切都很顺利。

在 Xcode 中: 转到 Window然后 Devices and Simulators。单击模拟器选项卡。单击左下角的 +按钮并添加 iPhone X。

我希望这对你来说和对我一样容易。

改变 /node_modules/@react-native-community/cli-platform-ios/build/commands/runIOS/index.js

文件

options: [{
name: '--simulator [string]',
description: 'Explicitly set simulator to use. Optionally include iOS version between' + 'parenthesis at the end to match an exact version: "iPhone 6 (10.0)"',

当我把 Xcode 10升级到 Xcode 11时，我遇到了同样的错误，但是指定模拟器版本对我来说是一个快速修复。

首先列出所有可用的 ios 模拟器

  xcrun simctl list devices | grep iPhone | grep -v unavailable | cut -d'(' -f1

结果

然后选择一个运行反应本机，例如

 react-native run-ios --simulator='iPhone 11 Pro Max'

小开

在我将 Xcode 更新到版本11之后，我遇到了同样的问题。

一个解决方案是将 iPhoneX 模拟器添加到您的列表中。

选择模拟器-> 硬件-> 管理设备(您将看到一个弹出窗口)
选择“模拟器”-> (左下角) + (加号图标，旁边的“过滤器”) ，然后添加一个新的模拟器,
模拟器名称: iPhone X 设备类型: 选择 iPhone X。

这招对我很管用

小开

对于 Xcode 11.2和 iOS 13.2，这里是我在模拟器中运行应用程序所做的更改

在 findMatchingSimulator.js

第43行:

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

到

if (!version.includes('iOS') && !version.includes('tvOS')) {

台词

52号线

if (
simulator.availability !== '(available)' &&
simulator.isAvailable !== 'YES'

continue;

if (
simulator.isAvailable != true
) {
continue;
}

第一天的反应项目广告已经降低它! (没有)

在我的情况下，我已经尝试其他以上的解决方案，但没有工作。

然后我尝试升级反应-自然从 0.59.5到 0.59.10，然后它的解决

对我来说，我必须通过运行 npx react-native-git-upgrade来将 React Natural 更新到0.60。

小开

我在尝试将 React National 从 0.59.8升级到 0.59.9后遇到了这个问题。

事实证明(基于上述答案) ，我们需要更新 @react-native-community/cli模块:

从锁文件(yarn.lock或 package-lock.json)中删除它
运行 yarn或 npm install再次安装它。

对我来说，解决这个问题的方法是没有设置 Xcode 命令行工具(xcrun simctl失败了)如果您刚刚重新安装了 Xcode，可能会遇到这个问题。

关于如何设置命令行工具，请参阅这篇文章。

在我的例子中，问题是在 xcode 更新之后，模拟器被删除了，我必须手动创建它(因为这个新的 xcode Version 没有默认设置)

你可以检查它是否和这里列出的设备一样:

xcrun simctl list devices

如果它在“不可用”标题下(因为您缺少 iOS 版本) ，您可以用当前版本创建一个，或者下载预期的运行时。

点击 XCode-> Window-> Device and Simulators，点击加号按钮，创建一个 iOS 版本的模拟器，如下所示:

这解决了我的问题。
