Do you have an Ethereum client running?

Please check out the documentation here: http://truffle.readthedocs.org

Please reopen if this doesn't fix your issue. Thanks!

@YyItRoad I have got the same problem,how you sovle it?

[diogocortiz]

Getting the same problem. I am using testrpc. Did you solve tis problem?

[tcoulter]

Did you guys run truffle migrate before running truffle serve? You need to deploy your contracts first before you can have a website that interacts with them.

[diogocortiz]

Yes, I did. I have tried again just to make sure i followed those steps and got the same error msg. Any clue?

[diogocortiz]

I have installed the envionment in a server in c9.io. I am accessing the web page using a remote browser. Could this be the problem (the browser could not load the credentials)?

[RunshanHu]

Getting the same problem. I'm using a remote virtual machine to developing the dapp and trying to access the website by local browser. Could this be the reason?

You need modify some files as this:
https://gengxuelei.github.io/2017/12/26/truffle%E5%AE%89%E8%A3%85%E6%8C%87%E5%8D%97/

modifypackage.json：

"dev": "webpack-dev-server --host 0.0.0.0 --port 8080"

modifytruffle.js：

development: {
  host: 'yourIp',
  port: 8545,
  network_id: '*' // Match any network id
}

modifyapp/javascripts/app.js：
change：
window.web3 = new Web3(new Web3.providers.HttpProvider("http://127.0.0.1:9545"));
to：

window.web3 = new Web3(new Web3.providers.HttpProvider("http://yourIp:8545"));

substitute npm run dev for truffle server：

npm run dev

fsevents error need use webpack box & substitute npm run dev for truffle server
