錯誤：交易恢復：對非合約賬戶的函式呼叫
在過去的兩天裡，我一直在嘗試調試它，這讓我發瘋了。測試契約時出現此錯誤：
Error: Transaction reverted: function call to a non-contract account. 這是最簡單的合約和最簡單的函式呼叫。它當然適用於混音。這是錯誤
npx hardhat.test：Factory 1) Should not throw error 0 passing (2s) 1 failing 1) Factory Should not throw error: Error: Transaction reverted: function call to a non-contract account at Factory.newToken (contracts/Factory.sol:13) at processTicksAndRejections (internal/process/task_queues.js:97:5) at HardhatNode._mineBlockWithPendingTxs (node_modules/hardhat/src/internal/hardhat-network/provider/node.ts:1070:23) at HardhatNode.mineBlock (node_modules/hardhat/src/internal/hardhat-network/provider/node.ts:369:16) at EthModule._sendTransactionAndReturnHash (node_modules/hardhat/src/internal/hardhat-network/provider/modules/eth.ts:1373:18) at HardhatNetworkProvider.request (node_modules/hardhat/src/internal/hardhat-network/provider/provider.ts:99:18) at EthersProviderWrapper.send (node_modules/@nomiclabs/hardhat-ethers/src/internal/ethers-provider-wrapper.ts:13:20)請有人幫忙。
這是我的設置：Factory.sol：

這意味著，介面試圖呼叫一個不存在的合約。
契約中的以下行觸發了錯誤。
uint x = IERC20(0x4F96Fe3b7A6Cf9725f59d353F723c1bDb64CA6Aa).balanceOf(address(this));查看您的安全帽配置，您使用了一個新的本地開發網路，其中
0x4F96Fe3b7A6Cf9725f59d353F723c1bDb64CA6Aa可能是一個空帳戶，因為我看不到在該地址部署 ERC20 的任何其他邏輯。我猜你打算做一個主網分叉（文件）。但是這個地址
0x4F96Fe3b7A6Cf9725f59d353F723c1bDb64CA6Aa不是乙太坊主網上的ERC20合約，你確定這個地址是正確的嗎？如果你輸入了一個有效的 ERC20 合約地址，你就不會收到這個錯誤。
