# 安裝RN遇到的坑

### IPHONEOS_DEPLOYMENT_TARGET is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.0.99


上網google，會得到很多類似下面的這種解答，但是並不是替換後存檔就有用。

換上後請進到專案資料夾下的ios folder，然後下`Pod install`

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
        end
    end
end

注意這個8.0必須跟你的platform :ios, '8.0'一致
`['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'`

如果你找到的版本是沒有版本號的，就直接貼上後做`Pod install`看看，我自己還沒試過沒版本號的

### nvm is not compatible with the "PREFIX" environment variable: currently set to "/usr/local"
Run `unset PREFIX` to unset it.


解法：到`node_modules>react-native/script/find-node.sh`這隻檔案裡，在最上面加上`unset PREFIX`，然後再試一次你的build指令，我是使用`yarn ios`
