尝试:

xcrun simctl 

在terminal收益率:

xcrun:错误:无法找到实用程序"simctl",无法找到开发人员工具或PATH

我有Xcode 6.2 Beta.

有什么建议？

我今天升级到Xcode 10.2，因为升级无法react-native run-ios通过cli 运行：

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

Found Xcode workspace a.xcworkspace

Could not find iPhone X simulator

Error: Could not find iPhone X simulator
    at resolve (/Users/user/Documents/work/a/a-light-ui/node_modules/react-native/local-cli/runIOS/runIOS.js:149:13)
    at new Promise (<anonymous>)

    at Promise.resolve.then (/Users/user/Documents/work/a/a-light-ui/node_modules/react-native/local-cli/cliEntry.js:117:22)    

如果我运行xcrun simctl list devices所有模拟器，则显示(Shutdown) (unavailable, runtime profile not found)：

iPhone X (7AADFA50-7B57-4A40-8434-9A86F345D7ED) (Shutdown) (unavailable, runtime profile not found)

自从将xcode升级到10.2以来，还有其他人遇到过RN的问题吗？它仍然可以通过Xcode ..起作用，但这意味着打开Xcode。

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

我总是遇到错误：找不到iPhone X模拟器
