代币开源时出现问题 Error! Unable to generate Contract ByteCode and ABI

Compiler debug log:
Error! Unable to generate Contract ByteCode and ABI
Found the following ContractName(s) in source code : Address, Context, IERC20, IMdexFactory, IMdexPair, IMdexRouter, ISwapMining, Ownable, SafeMath, token
But we were unable to locate a matching bytecode (err_code_2)
For troubleshooting, you can try compiling your source code with the Remix - Solidity IDE and check for exceptions

编译器版本是正确的 第一次开源成功了 后面开源时就出现这个问题了

用编译错误提示的开发工具，再编译一次。
