Truffle 部署錯誤：沒有針對其目前網路 ID 的網路配置 (97)

我在部署與 Truffle 的契約時遇到問題。合約建構子採用文件中的 7 個參數2_deploy_xxx.js。但是，每次我在部署實際合約時都會遇到錯誤。合約需要一個預言機（來自 ChainLink 的 AggregatorV3Interface）。我很困惑，想知道是否有人能幫助我，因為我已經盯著這個太久了。

我的問題的解決方案是將 AggV3Int 作為必需的工件刪除，分配已部署的 oracle 的地址，並將部署器功能更改為非同步await部署器.deploy。

測試網連結的額外 2 個參數 0 和 10 是什麼？我認為如果您更改提供者： () => new HDWalletProvider(BSC_TESTNET_DEPLOYER_KEY, https://data-seed-prebsc-1-s1.binance.org:8545, 0, 10),

到

提供者：() => 新 HDWalletProvider(BSC_TESTNET_DEPLOYER_KEY, https://data-seed-prebsc-1-s1.binance.org:8545),

它應該工作。
