在 Polygon 主網上部署智能合約時的問題

我正在嘗試在 Polygon 主網上部署智能合約，但是當我使用 truffle 執行遷移命令時會發生這種情況

> Network name:    'matic'
> Network id:      137
> Block gas limit: 30176202 (0x1cc73ca)

Truffle v5.5.1 (core: 5.5.1)

這是我的 truffle-config.js

matic: {
       provider: () => new HDWalletProvider(mnemonic, `https://polygon-mainnet.g.alchemy.com/v2/key`),
       network_id: 137,
       confirmations: 2,
       timeoutBlocks: 200,
       skipDryRun: true
     },

低價交易通常意味著您的 gasPrice 太低，請嘗試在您的配置中設置自定義 gasPrice：https ://trufflesuite.com/docs/truffle/reference/configuration

您可以使用它來查看目前的 gas 價格是多少：https ://polygonscan.com/gastracker

請注意，gasPrice 以 wei 為單位
