我尝试了升级版本 truffle、testrdc、ganeche 但它仍然是错误的。

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

如果有任何好的理想，请帮助我。

谢谢，

Answer 1

当我使用“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。

Answer 2

这是事实发生后的很长一段时间，但我刚刚遇到了这个问题，这是用于编译的编译器 evmVersion 和用于 ganache-cli 的不匹配。 Ganache 指定了拜占庭，编译器默认为其他内容（早期版本？）

Answer 3

这解决了问题

npm i -g truffle@v5.0.5
