我试图在mac上模拟项目，离子得到错误：
No target specified for emulator. Deploying to iPhone-6s-Plus, 9.3 simulator
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):
Invalid device state
Error: ENOENT: no such file or directory, stat '/Users/Alex/Library/Logs/CoreSimulator/04A637E3-A6C4-4180-AAB7-E50164F4DD0F/system.log'
但是构建和添加平台已成功结束。
