今天刚升级到Xcode10，就遇到两个报错问题
错误一：Xcode 10: Build input file double-conversion cannot be found
error: Build input file cannot be found: '../node_modules/react-native/third-party/double-conversion-1.1.6/src/strtod.cc'
configure: error: in `../node_modules/react-native/third-party/glog-0.3.4'

at process._tickCallback (internal/process/next_tick.js:189:7)解决办法，在项目文件夹下执行：
第一步
cd node_modules/react-native/scripts && ./ios-install-third-party.sh && cd ../../../
第二步
cd node_modules/react-native/third-party/glog-0.3.5/ && ../../scripts/ios-configure-glog.sh && cd ../../../../注意：第二步命令“golg-0.3.5”需要改成你的glog版本，比如我的是“golg-0.3.4”，则改成
cd node_modules/react-native/third-party/glog-0.3.4/ && ../../scripts/ios-configure-glog.sh && cd ../../../../可以在以下文件夹查看你的golg，如图
第三步重启服务：npm start
