初始化React-native,执行run-ios报错了

Question

第一跑react-native的脚手架，不知道怎么进坑了

我的操作过程就是

react-native init myApp

cd myApp

react-native run-ios

** BUILD FAILED **



The following commands produced analyzer issues:
    Analyze /Users/scdzs5/wh/project/hpApp/node_modules/react-native/ReactCommon/yoga/yoga/YGNodeList.c
    Analyze /Users/scdzs5/wh/project/hpApp/node_modules/react-native/ReactCommon/yoga/yoga/Yoga.c
(2 commands with analyzer issues)

The following build commands failed:
    PhaseScriptExecution Install\ Third\ Party /Users/scdzs5/wh/project/hpApp/ios/build/Build/Intermediates/React.build/Debug-iphonesimulator/double-conversion.build/Script-190EE32F1E6A43DE00A8543A.sh
(1 failure)

Installing build/Build/Products/Debug-iphonesimulator/hpApp.app
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/hpApp.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist

我应该怎么做呢？

Answer 1

测试版本：

"react": "16.0.0-alpha.12",
"react-native": "0.45.0"

切换成下面的版本就可以了：

"react": "16.0.0-alpha.6",
"react-native": "0.44.3"

具体操作：删除node-modules文件夹，修改pakage.json文件，然后执行npm install

Answer 2

删掉ios/build 目录，重新run看下

Answer 3

版本问题。
删除node-modules文件夹，修改pakage.json文件，然后执行npm install
