我无法迁移truffle init附带的标准合同。这就是我的所作所为:
truffle init
truffle compile
truffle migrate
这是我在init时生成的内容:
但是当我迁移时,会出现以下错误列表:
Error: Invalid JSON RPC response: ""

对于Solidty To Migrate,本地以太坊区块链应该已经运行,您要迁移的智能合约应该转到正确的Local Ethereum区块链,因此您需要检查本地以太坊区块链的端口号。
ganache-cli
或testrpc
(用于制作本地区块链)。它具有在其下面运行的端口号。例如http://localhost:8545
。truffle.js
文件并检查该端口应为8545
。truffle migrate
迁移智能合约。答案 2 :(得分:0)
合同名称不应与功能名称相同。
