Hmm...did you try installing with npm instead of yarn? Do you have current versions of node and npm? I opened my /module.config.js file and I have the es5 version that is in the ipfs-api package and it ran without problems. Trying to think what else it might be...

I met this error:

TypeError: WEBPACK_IMPORTED_MODULE_0__web3.a.eth.Contract is not a constructor

./src/storehash.js

e:/eth-ipfs/src/storehash.js:37

34 | "type": "function" 35 | } 36 | ]

37 | export default new web3.eth.Contract(abi, address); 38 | 39 | 40 | // WEBPACK FOOTER // View compiled

I suspect it is because my web3 version is 0.20.0. CMD is always wrong when I install Web3 0.1.0, and the installation is unsuccessful.
