Not sure why I'm getting this. I've tried installing the specific web3 and truffle-contract (as listed in the package.json file).

According to this comment https://github.com/trufflesuite/ganache-cli/issues/476#issuecomment-372534288 toBigNumber was renamed to toBN in version 1.0.0 of web3. To solve your problem use a compatible version of web3, for example 0.20.6.

Reinstalling web3@0.20.6 worked for me.
