Origin: Branched react-web3 package installation fails silently

[micahalcorn]

In step 10 of the local DApp installation, there are no obvious errors during npm install. However, upon npm run start, I get the following error:

Failed to compile.

Error in ./src/components/app.js
Module not found: 'react-web3' in /.../Solidity/origin-demo-dapp/src/components

 @ ./src/components/app.js 20:16-37

Sure enough, the node_modules/react-web3 folder only contains README.md and package.json. It is missing the dist folder and the package code. If I remove the installed branch of the package and edit the package.json dependency to "react-web3": "0.4.3", then the app boots up fine. I have tried a variety of removals and reinstalls to no avail. Let me know what else I can tell you.

I am also experiencing this issue.

Ok, this appears to be a node version issue.

Doesn't seem to compile on v6.11.1 or v7.0.0, but does work on v8.5.0.

Using nvm, this should get it working:

$ nvm install v8.5.0 && nvm use v8.5.0

Should probably document this somewhere. I think we can also specify the version in the engines field, both in this repo and in the react-web3 repo. I'll look into that.

Good catch @tyleryasaka , I've updated the readme.
https://github.com/OriginProtocol/demo-dapp/commit/8d5fde6819eb4569419ed151cc9ae6ce332c0379

The engines field seems to not really be enforced anywhere.

@wanderingstan Great! Yeah I noticed the same issue with the engines field. Doesn't seem very useful.

@tyleryasaka @micahalcorn Are we in agreement that this is a node version issue, and I can close this issue?

[tyleryasaka]

@wanderingstan Yes I feel confident that's what it is. I think if @micahalcorn can confirm that this fixes the issue for him then this is good to close.

@wanderingstan Confirmed on 8.5.0 and 8.9.4. Thanks @tyleryasaka!
