在使用truffle migrate进行智能合约test环境发布时如果未配置正确会出现以下异常:
$ truffle migrate
Error: No network specified. Cannot determine current network.

导致上面异常的原因为是因为truffle.js里面未配置链接合约发布的环境地址,找到对应的truffle.js文件,修改代码为类似如下配置即可解决问题:
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
network_id: "*" // 匹配任何network id
}
}
};
