Expo React-Native iOS模拟器无法正常工作 [英] Expo React-Native iOS Simulator not working
问题描述
你好，我遇到了Expo React-Native的问题.每当我尝试启动iOS模拟器时.我收到此错误:
Hello I'm facing a problem with Expo React-Native. Whenever I try to launch the iOS Simulator. I get this error:
Simulator is installed but is identified as 'com.apple.CoreSimulator.SimulatorTrampoline'; don't know what that is.
Simulator not installed. Please visit https://developer.apple.com/xcode/download/ to download Xcode and the iOS simulator. If you already have the latest version of Xcode installed, you may have to run the command `sudo xcode-select -s /Applications/Xcode.app`.
我的NPM版本为 6.7.0 react-native-cli: 2.0.1 react-native: 0.57.1 博览会版本 2.11.9
My NPM Version is 6.7.0 react-native-cli: 2.0.1 react-native: 0.57.1 Expo Version 2.11.9
我还要确保Xcode上的命令行工具设置正确 Xcode CommandLineTools
Also I made sure my Command Line tools on Xcode is setup perfectly Xcode CommandLineTools
最后，我还尝试运行命令sudo xcode-select -s /Applications/Xcode.app
Finally, I also tried to run the command sudo xcode-select -s /Applications/Xcode.app
什么都没有.
推荐答案
我遇到了同样的问题，可以通过在启动博览会之前手动启动模拟器应用程序来解决此问题.
I had the same problem, fixed it by manually starting the simulator app before starting expo.
该应用程序位于/Applications/Xcode.app/Contents/Developper/Applications/Simulator.app
The app is located in /Applications/Xcode.app/Contents/Developper/Applications/Simulator.app
