Uncaught TypeError: (intermediate value).toBigNumber is not a function

[Rich2020]

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

truffle-contract.js:29 Uncaught TypeError: (intermediate value).toBigNumber is not a function

According to this comment trufflesuite/ganache#476 (comment)
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 [email protected] worked for me.

0.20.6 worked for me too
