1按照https://reactnative.cn/

操作：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"[/code] 
出现需要brew更新错误信息后 ，去往目录手动删除就可以了，不要rm -rf（后果很惨痛）


输入：react-native run-ios   出现以下错误

he following build commands failed:

PhaseScriptExecution Install\ Third\ Party /Users/kangxg/AwesomeProject/ios/build/Build/Intermediates/React.build/Debug-iphonesimulator/double-conversion.build/Script-190EE32F1E6A43DE00A8543A.sh

(1 failure)

Installing build/Build/Products/Debug-iphonesimulator/AwesomeProject.app

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):

Failed to install the requested application

An application bundle was not found at the provided path.

Provide a valid path to the desired application bundle.

Print: Entry, ":CFBundleIdentifier", Does Not Exist

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/AwesomeProject.app/Info.plist

Print: Entry, ":CFBundleIdentifier", Does Not Exist

运行 AwesomeProject.xcodeproj  错误：#include <boost/iterator/iterator_adaptor.hpp>



原因：init命令默认会创建最新的版本，而目前最新的0.45版本需要下载boost库编译。此库体积庞大，在国内即便翻墙也很难下载成功，导致很多人无法正常运行iOS项目，推荐暂时使用0.44.3的版本。

解决办法： 创建项目暂时先使用react-native init AwesomeProject --version 0.44.3，指定某个版本。

再次react-native run-ios  运行 AwesomeProject.xcodeproj





运行成功

如果 要运行最新的0.45版本 需要 brew install boost

安装 boost 库即可，但在最后生成软链接的过程中可能出目录写权限的报错问题

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink include/boost
/usr/local/include is not writable.

观察报错信息发现/usr/local/include与/usr/local/lib无法写入，

故手动修改权限：

sudo chmod -R 777 /usr/local/include
sudo chmod -R 777 /usr/local/lib
1

之后 brew link boost 库即可

如果上面还是解决不了，就是初始化的时候，有四个包没有安装完整参考下面的地址去做即可解决：
