Getting this error:

  throw new Error(message);
        ^
Error: More than one instance of bitcore found with different versions: v0.11.7 and v0.11.7. Make sure there are no version conflicts between package.json files of your dependencies. This could also happen when a package depends on a git repository.

Solution 1:

Temporary workaround:

var bitcore = require('bitcore');
delete global._bitcore;

Solution 2:

~/.nvm/versions/node/v4.8.3/lib/node_modules/bitcore/node_modules/insight-api/node_modules/bitcore-lib/index.js

line 7:
bitcore.versionGuard = function(version) {
Change it to:
bitcore.versionGuard = function(version) { return;
