Reference Error - not defined (develop console)

See original GitHub issue

I’ve asked for help in the Truffle Gitter before filing this issue.

truffle(development)> Election.deployed().then(function(instance) { app = instance })
ReferenceError: Election is not defined
truffle(development)> app.address
ReferenceError: app is not defined

Not sure why I’m receiving reference errors. No one replied on Gitter, and a Google search offered no solutions.

Environment

Operating System: Windows 10
Truffle version (truffle version): 4.1.8

@ArranMcC To use deployed you’ll need to run migrate first. This deploys your contracts to the test chain managed by the develop shell. The metacoin box is a working example you might find helpful, and check out the migrations documentation for help on writing deployment scripts:

$ mkdir metacoin
$ cd metacoin
$ truffle unbox metacoin
$ truffle develop

# ..... client launches ....

truffle(develop)> MetaCoin.deployed()
ReferenceError: MetaCoin is not defined . # <--- Your error
truffle(develop)> migrate                 # <--- Run `migrate` 
Compiling ./contracts/ConvertLib.sol...
Compiling ./contracts/MetaCoin.sol...
Compiling ./contracts/Migrations.sol...

# .... etc ....

Writing artifacts to ./build/contracts

Thanks! I think it was just due to truffle not being unboxed into an empty directory, something which the tutorials I was following didn’t mention as they maybe thought it was obvious.
