Client Side: Cannot find module 'bitcore-lib' at a (bitcore-mnemonic.min.js:1)

[360disrupt]

I installed the library with bower install bitcore-mnemonic --save but I get the following error:

Uncaught Error: Cannot find module 'bitcore-lib'
    at a (bitcore-mnemonic.min.js:1)
    at o (web3.min.js:1)

If I install and include bitcore-lib with bower I get this error:

bitcore-lib.js:54088 Uncaught Error: More than one instance of bitcore-lib found. Please make sure to require bitcore-lib and check that submodules do not also include their own bitcore-lib dependency.
