title: Fatal error when initializing core config
body: <p>I am a rookie in hyperledger in China.</p>
  <p>I followed the order of the official documents</p>
  <p>My fabric version is up to date （2020.10.10）and I attend a error when i carry out this moment：</p>
  <p><code>./network.sh deployCC</code>,</p>
  <p>I found an answer in the official documentation, and have an error in <code>test-network</code>.</p>
  <p>I carried out <code>fabric-samples/facar/startFabric.sh</code> and carried out <code>peer chaincode query -C mychannel -n fabcar -c '{&quot;Args&quot;:[&quot;queryAllCars&quot;]}'</code> in <code>test-network</code> directory.</p>
  <p>However, there is a new problem:</p>
  <p><code>fatal error when initializing core config : Could not find config file. Please make sure that FABRIC_CFG_PATH is set to a path which contains core.yaml</code>,</p>
  <p>I set up this path already, why?</p>
  <p>My English is not very good, I'm sorry <code>:(</code></p>
