【问题描述】：
版本
"web3": "^1.2.1"
"react-native": "0.59.10"
从set-up tutorial 和https://github.com/ethereum/web3.js/issues/1022，我能够在react-native 中安装web3，但是我收到了这个错误：
错误
Possible Unhandled Promise Rejection (id: 1):

当我执行诸如web3.eth.getTransactionCount 或web3.eth.getBlock('latest') 之类的promise 方法时发生错误。
试试
我试过console.log(web3.version)，完全没问题

给我看你正在尝试的代码，而不是你研究的链接。
