Truffle migrate Could not connect to your Ethereum client

Question

I am trying to implement truffle metacoin tutorial. When i run truffle migrate, I get the following error. How to solve this?

Could not connect to your Ethereum client. Please check that your Ethereum client:
    - is running
    - is accepting RPC connections (i.e., "--rpc" option is used in geth)
    - is accessible over the network
    - is properly configured in your Truffle configuration file (truffle.js)

Answer 1

As mentioned in the previous answer, you have to run testrpc first. If testrpc is running and still you get this error then make sure that you have added the port number of testrpc right. By default, testrpc will run on port 8545, so your  truffle.js file should look something like this:

module.exports = {
    networks: {
        development: {
//Other entries
            port: 8545,            
// Remaining entries

        }
    }
};

Hope these information helps.

Had the same problem. I had not configured the truffle.js file. It worked after I configured it. Thanks!

It seems like your network is not running. Open another terminal and run

testrpc

and then run 

truffle migrate

You have to start the rpc first. You can use the following command for it:

$ geth --rpc
