本文介绍了一种在使用Truffle框架进行智能合约部署时遇到的常见错误及其解决方案。当尝试运行`truffle migrate`命令时，可能会出现由于未运行Ethereum客户端导致的错误。文章详细说明了如何通过启动testrpc来解决此问题。

Usage
To initialize a project with this exapmple, run truffle init webpack inside an empty directory.
Building and the frontend
First run truffle compile, then run truffle migrate to deploy the contracts onto your network of choice (default “development”).

Then run npm run dev to build the app and serve it on http://localhost:8080

直接安装这会出现错误:

nk@ubuntu:~/myProject$ truffle migrate
Error: Invalid JSON RPC response: ""
    at Object.InvalidResponse (/usr/local/node/lib/node_modules/truffle/node_modules/web3/lib/web3/errors.js:35:16)

    at ClientRequest.emit (events.js:188:7)
    at Socket.socketErrorListener (_http_client.js:309:9)
    at emitOne (events.js:96:13)

解决方法:

I figure it out. The reason is because no Ethereum client is running. we just need to run testrpc in another terminal.

另起一终端:
nk@ubuntu:~$ testrpc -a

问题解决.
