[voith]

Yup, been fighting it myself for sometime. As a quick fix install 4.6.0 till the team actually fixes this.

[RomanUsov]

I have the same problem as artyomLisovskij.

[RomanUsov]

I have managed this issue.
In my case:

• Install python-dev sudo apt install python3.6-dev (I use Ubuntu 16.04 and python 3.6)
• Clone repo git clone git@github.com:ethereum/web3.py.git
• cd to web3 folder cd web3.py
• pip install .

After these steps I have installed web 4.7 version

Sorry for the downtime in prod! This is now fixed in v4.7.1. See #1053 for more explanation.
