智能合约部署truffle migrate时出现错误

控制台输入truffle migrate提示：
There was a timeout while attempting to connect to the network.check to see that your provider is valid.If you have a slow internet connection,try configuring a longer timeout in your truffle config.
意思是连接超时，检查你的设置。如果你的网速有点慢，把“timeout”调长一点。

在项目的truffle-config.js调truffle的设置：

mocha:{
	//timeout:200000  //我把原来的100000调成了200000，就OK了
}

再部署就成功了
