松露“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，我正在尝试将其部署到 BSC 测试网。

这就是我在 truffle-config.js 文件中的内容（privateKeys 是一个数组，其中包含单个条目 ['0x + privatekey']：

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，我收到以下错误：

Compiling your contracts...
===========================
> Everything is up to date, there is nothing to compile.



Starting migrations...
======================
> Network name:    'bscTestnet'
> Network id:      97
> Block gas limit: 30000000 (0x1c9c380)

Answer 1

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

Answer 2

更新： 对，解决方法：我将 @HDWalletProvider 回滚到 v2.0.1 并且能够迁移。

我认为今天更新的 ppl 的新版本一定有问题。

=================

Polygon Mumbai 也有同样的问题。

函数“cb”指的是回调函数。奇怪的是错误消息根本没有引用我自己的代码；它引用了位于以下位置的 migrations.js：

<.nvm processticksandrejections>

这让我相信 1_initial_migration.js 有问题...但是这是自动生成的，所以我看不到任何问题...这很奇怪。

1_initial_migration.js：

const Migrations = artifacts.require("Migrations");

module.exports = function(deployer) {
  deployer.deploy(Migrations);
};
