Truffle '“迁移”——cb 不是函数'

Question

我在 Solidity 0.6.6 中编写了一个简单的智能合约，并尝试将其部署到 BSC 测试网。

这就是我的 truffle-config.js 文件中的内容（privateKeys 是一个包含 ['0x + privatekey'] 单个条目的数组：

networks: {
   bscTestnet: {
      provider: () => new HDWalletProvider(
        privateKeys,
        'https://data-seed-prebsc-1-s1.binance.org:8545/'
      ),
      network_id: 97,
      skipDryRun: true
   }
}

当我运行命令“truffle migrate --reset --network bscTestnet”时，出现以下错误：

Compiling your contracts...

Starting migrations...
======================
> Network name:    'bscTestnet'
> Network id:      97

打开了一个关于它的问题：https://github.com/trufflesuite/truffle/issues/4676 我猜它是 HardwareWallet2.0.2 中的一个错误。恢复到 HardwareWallet2.0.0 解决了我的问题

npm i @truffle/hdwallet-provider@2.0.0
