我一直在遵循shoutem教程here，但无法设置本地环境。关于本教程，我已将所有内容安装在“前提条件”下，克隆了在构建器中制作的空白shoutem应用程序，并按照以下步骤为ios here运行本地环境。运行“ react-native run-ios”会出现以下错误：
error: Build input file cannot be found: '/Users/USERNAME/TestApp/node_modules/react-native/third-party/double-conversion-1.1.5/src/diy-fp.cc'
** BUILD FAILED **

我尝试卸载并重新安装node_modules，并升级react-native。我尝试了许多其他建议，其中一些让我更改了xcode的构建路径，但没有一个奏效（不幸的是，我尝试了太多记不起来）。我没有足够的经验来了解到底发生了什么。
我当前的版本：
react-native-cli：2.0.1
react-native：0.56.0
纱：1.10.1
npm：6.4.1
xcode：10
