EtherSim exception thrown during based truffle test

[taoeffect]

Copied from: trufflesuite/truffle#54 (comment)

@tcoulter EtherSim from npm still tries to install an outdated secp256k1, causing it to fail:

ethersim/node_modules/ethereumjs-block/node_modules/secp256k1

> [email protected] install /usr/local/lib/node_modules/ethersim/node_modules/ethereumjs-vm/node_modules/secp256k1

The develop copy per your instructions has the correct version and therefore installed, but running truffle test caused it to throw an exception:

-> % ./bin/ethersim -p 8545
EtherSim v0.1.6

truffle test got as far as:

@taoeffect I'm not sure why this bug happens, but someone else had the same issue. I've apparently fixed it in the updated version of my branch: https://github.com/tcoulter/EtherSim

@tcoulter Your repo worked! 👍

-> % ./bin/ethersim -p 8545

Now just to have your changes merged into the official branch. :)

released 0.2.0 with the latest changes

Getting the same error in 0.2.0 using the multiply contract (I ported the test code to nodejs but that shouldn't matter). Test code attached. Output below.

Possibly using a later version of web3 than you?
