我试图用松露4.1.0调试代码的密实度。调试器能够正常启动,显示第一行,但你无法通过合同的一步!
如在终端显示的错误的完整堆栈跟踪是:
TypeError: Cannot read property 'line' of undefined

挖掘到方法formatRangeLines: function(source, range, contextBefore)
当console.log(range);
它打印:
{ start: undefined, end: undefined }
事实上,除了在这个块存取range.start
时提出:
var startBeforeIndex = Math.max(
range.start.line - contextBefore, 0
);
有什么建议么?谢谢,
更新:这个问题在松露版本4.1.4得到解决(reference)。
但是,如果你更新你的松露版本,但仍然面临的问题。试着在你的控制台上运行(这是强制更新所有已编译的智能合同字节码根据最新的版本是):
truffle migrate --reset --compile-all
由于在松露调试器的当前版本中的错误(即实验版),调试器不能跳跃到另一个文件。
该缺陷是这里提出:https://github.com/trufflesuite/truffle/issues/826
因此,要克服当前的错误,所有的智能合约代码必须是在一个文件中。希望有一个工具,可以帮助这一点:https://github.com/poanetwork/solidity-flattener
