React Native 应用程序无法安装具有 Solana 依赖项的包

Question

在 React Native 中安装需要 solanaweb3js 的包会引发错误。

我发现我并不孤单但我无法让提供的解决方案为我工作。

错误：

Error: Unexpected token name «n», expected punc «,» in file node_modules/solana-test-package/node_modules/@solana/web3.js/lib/index.native.js at 4581:32

重现错误： 克隆： https://github.com/Darjusch/AwesomeProject

或

npx react-native init AwesomeProject

npm i solana-test-package

我上传了 npm packge 来重现该问题： https://github.com/Darjusch/solana-test-package

这是包装内容：

index.js

const { Keypair } = require('@solana/web3.js');

export function generateKeypair() {
  const keypair = Keypair.generate();
  console.log(`Generated Solana publickey is ${keypair.publicKey.toBase58()}`);
  return keypair;
}

package.json

 "dependencies": {
    "@solana/web3.js": "^1.54.0"
  }

如有任何帮助！

Answer 1

该错误意味着您的 JavaScript 运行时不理解

BigInt

文字（例如

2n

）。像 Hermes 这样的较新的运行时大约在 React Native 0.70.0 中添加了对它们的支持。

按照更新后的 React Native 项目初始化说明进行操作：https://solanacookbook.com/integrations/react-native.html#how-to-use-solana-web3-js-in-a-react-native-app
