react-native run-ios无法找到任何模拟器 [英] react-native run-ios can not find any simulator

问题描述

我一直面临着一个问题，即无论我添加到--simulator参数中的模拟器如何，"react-native run-ios"都无法启动. XCode具有命令行工具"的正确位置

I have been facing an issue where 'react-native run-ios' can not start, regardless of the simulator I add to the --simulator argument. XCode has the correct location for the 'command line tools'

我总是收到错误消息: 找不到iPhone X模拟器

I am always getting the error: Could not find iPhone X simulator

推荐答案

我找到了一个临时解决方法:

I've found a temporary fix:

在以下文件中:

/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

...将第42行更改为:

...change line 42 to:

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