找到myproject/node_modules/react-native/React/Base/RCTModuleMethod.mm. 【或者（.m）】文件
修改static BOOL RCTParseUnused 方法如下：
static BOOL RCTParseUnused(const char **input)
{
return RCTReadString(input, “unused”) ||
RCTReadString(input, “__attribute((unused))”) ||
RCTReadString(input, “attribute((unused))”);
}
重新编译
注入的js代码超行的问题，把js代码压缩成一行就好了。
import {
Platform,
} from ‘react-native’;
scalesPageToFit={Platform.OS === ‘ios’? false : true}
ios正常，android模拟器提示TypeError: Network request failed。
fetch的地址是localhost报错的，换个ip解决问题。

什么是 ADB?
Android调试桥（ adb ）是一个开发工具，帮助安卓设备和个人计算机之间的通信。 这种通信大多是在USB电缆下进行，但是也支持Wi-Fi连接。 adb 还可被用来与电脑上运行的安卓模拟器交流通信。 adb 对于安卓开发来说就像一把“瑞士军刀”。
通过 Homebrew 安装
brew install android-platform-tools
测试是否正常安装
adb devices
xcrun: error: unable to find utility “instruments”, not a developer tool or in PATH
在终端执行如下命令 sudo xcode-select -s /Applications/Xcode.app/Contents/Developer/
