我打算使用ethereumjs-wallet
。但是我决定使用ethereumjs-wallet-react-native
,因为它用于网络。如果您查看the link,它会显示import
两个模块。因此,我采用了两个模块,并尝试import
进行操作,但是出现了问题。
引起错误的代码:
import { asyncRandomBytes } from 'react-native-secure-randombytes'
import safeCrypto from 'react-native-safe-crypto'
window.randomBytes = asyncRandomBytes
window.scryptsy = safeCrypto.scrypt
错误消息:
无法解析模块“ react-native-secure-randombytes”
我想解决这个问题,但是无法解决,所以我决定绕行。
已解决错误的代码:
import safeCrypto from "react-native-fast-crypto";
const { RNRandomBytes } = NativeModules;
window.randomBytes = RNRandomBytes.randomBytes;
window.scryptsy = safeCrypto.scrypt;
稍后可能会引起问题,但现在已解决。但是,当我们调用并执行ethereumjs-wallet-react-native.
错误消息:
位于“ node_modules / ethereumjs-wallet-react-native / index.js”的软件包 尝试导入节点标准库模块“ crypto”。它 失败,因为React Native不包含Node标准 图书馆。阅读更多 https://docs.expo.io/versions/latest/introduction/faq/#can-i-use-nodejs-packages-with-expo
所以我下载了crypto-browserify
,但是没有用。
尝试解析的代码
import safeCrypto from "react-native-fast-crypto";
const { RNRandomBytes } = NativeModules;
import Wallet from "ethereumjs-wallet-react-native";
var crypto = require("crypto-browserify");
window.randomBytes = RNRandomBytes.randomBytes;
window.scryptsy = safeCrypto.scrypt;
...
async componentDidMount() {
const wallet = await Wallet.generate();
}
这是package.json:
"dependencies": {
"crypto-browserify": "^3.12.0",
"ethereumjs-wallet-react-native": "^0.6.7",
"expo": "^32.0.0",
"expokit": "32.1.1",
"react": "16.5.0",
"react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
"react-native-fast-crypto": "^1.8.1",
"react-native-randombytes": "^3.5.2"
},
"devDependencies": {
"babel-preset-expo": "^5.0.0"
},
“ ethereumjs-wallet-react-native / index.js”的代码位于我的文章the link上。
请帮助我们。预先谢谢你。

react-native-randombytes
被重新链接。
和
我曾经import crypto from "crypto";
重新创建成功的代码
import crypto from "crypto";
import safeCrypto from "react-native-fast-crypto";
import { asyncRandomBytes } from "react-native-secure-randombytes";
...
window.randomBytes = asyncRandomBytes;
window.scryptsy = safeCrypto.scrypt;
