Bump eth_utils requirement and start using eth_utils.toolz

• Version: 4.7.1

replace web3.utils.toolz with eth_utils.toolz

@dylanjw So I tried doing this (branch here), but ran into some dependency conflicts related to eth-typing:

ethtoken==0.0.1a3
  - web3 [required: ~=4.0b7, installed: 4.7.1]
    - cytoolz [required: >=0.9.0,<1.0.0, installed: 0.9.0.1]
      - toolz [required: >=0.8.0, installed: 0.9.0]
    - eth-abi [required: >=1.2.0,<2.0.0, installed: 1.2.0]
      - eth-typing [required: <=2, installed: 2.0.0]
      - eth-utils [required: >=1.2.0,<2.0.0, installed: 1.2.2]
        - cytoolz [required: >=0.8.2,<1.0.0, installed: 0.9.0.1]
          - toolz [required: >=0.8.0, installed: 0.9.0]
        - eth-hash [required: >=0.1.0,<1.0.0, installed: 0.2.0]
        - eth-typing [required: >=1.3.0,<2.0.0, installed: 2.0.0]

* py-evm==0.2.0a32
 - eth-typing [required: >=1.1.0,<2.0.0, installed: 2.0.0]
* ethtoken==0.0.1a3
 - web3 [required: ~=4.0b7, installed: 4.7.1]
* eth-utils==1.2.2
 - eth-typing [required: >=1.3.0,<2.0.0, installed: 2.0.0]

I tried messing around with the dependency restrictions, but it comes down to the latest version of eth-abi (including the betas) being flexible enough to use 2.x of eth-typing (see here), so I'm hesitant to make that more restrictive instead of opening it up. Not sure what the best approach would be here. @carver - any thoughts?

Also, for what it's worth, I'm getting this on master when I run pip install -e ".[dev]" with the cache deleted:

eth-utils 1.2.2 has requirement eth-typing<2.0.0,>=1.3.0, but you'll have eth-typing 2.0.0 which is incompatible.
py-evm 0.2.0a32 has requirement eth-typing<2.0.0,>=1.1.0, but you'll have eth-typing 2.0.0 which is incompatible.
ethtoken 0.0.1a3 has requirement web3~=4.0b7, but you'll have web3 4.7.1 which is incompatible.

EDIT: Looks like this was already addressed :)
ethereum/eth-abi#99 / ethereum/eth-abi#100
I think once a patch of eth-abi 1.x is released I can finish up that PR.

Logged the issue above. Cross-post from the PR for that issue:

It is interesting that we have a circular dependency on Web3 here. I think the order needs to be:

1. eth-abi-1.2.1 is released and includes the exclusion of eth-typing >= 2
2. web3-v4.7.2 will pick this up as it's >=1.2.0
3. Bump the version here to include non-beta 4.x Web3, which should include the change above. Release.
4. Web3 will pull in the latest version of ethtoken-0.0.1-alpha.4, which will not have an incompatibility with the Web3 version being installed.

Then we might want to lock the docs version of ethtoken to ethtoken>=0.0.1-alpha.4,<2.0.0 as part of this issue?

Yes, you may!

@pipermerriam I am beginner in open source contribution.

I got inspired to work on project web3 that can change the world.
Can you please guide me to work on this issue.

Isn't it already fixed with #1317?

[kclowes]

Yep, looks like it. Thanks @BoboTiG!
