我尝试了升级版本truffle、testrdc、ganeche，但仍然是错误的

$ npm install -g truffle@latest
$ npm install -g ethereumjs-testrpc@latest
$ npm install -g ganache-cli@latest

如果你有什么好的想法，请帮助我

谢谢，

在使用“testrpc”命令启动本地区块链时，我也遇到了同样的错误。

当我使用“ganache cli”命令启动本地区块链时，错误得到了解决。

这是一个很长的时间，但我刚刚遇到了这个问题，这是用于编译和ganache cli的编译器evmVersion不匹配。Ganache指定了拜占庭，编译器默认为其他版本（早期版本？

Hi Pravin，我删除了它们并重新安装，然后解决了问题。
