I am using a Mac 10.14 mojave,
python versionPython 3.6.3 :: Anaconda, Inc.

I have already tried the following:
xcode-select --install
sudo xcode-select --reset
and then attempted to reinstall web3, getting the above error again.
I was able to install ipython no problem. I am wondering if my issue is anaconda being set as my default python? If so how do I fix this. If not, any suggestions?

[kclowes]

I'm not quite sure what's going on here. Initially I was thinking that maybe the version of cytoolz might not be compatible with web3, but I was able to install cytoolz==0.11.0 and run web3 with no problem. Does starting over in a new virtual environment solve the problem?

[donsmeed]

Let me try that

[donsmeed]

OK I just spun up a virtual enviroment, upgraded pip and retried downloading web3 by
running pip install web3. In the middle of the below error code it states:
ALERT: Cython not installed. Building without Cython Running setup.py install for cytoolz ... error
I am wondering if not having cython installed is the source of my above problem. I did get one other error message.
At the bottom I got this error:

I'm going to look into this a little more because it keeps coming up, but I've had success in the past uninstalling and then reinstalling gcc. I haven't taken the time to figure out the root cause, however. It may be Cython not being installed like you mentioned, but I don't see it installed on my machine, so I don't think that's it. You might try running xcode-select --install again as well to get the latest version of clang. I'll keep digging and let you know if I see anything else, but let me know if you get it figured out in the meantime.

I'd also like to note that I think the solution to this issue deserves being put in the troubleshooting section of the docs.

[kclowes]

So I just checked and I am able to replicate the failed install in a fresh env but it's not quite the same problem as yours. It looks like mine is due to the watchdog library, but for whatever reason upgrading pip fixes my issue. I'll keep digging on Monday.

Thank you for you help

[maxwolff]

also had trouble pip install ing, error building wheel for bitarray, cytoolz, and lru-dict

mac os x 10.15
python 3.8

https://pastebin.com/aDu1zGWk

ended up just bumping down to python 3.7 and got it to work

[nraychaudhuri]

3.7 worked for me as well. Thanks for the tip @maxwolff

[Kagerrak]

have the same issue tried everything in here including bumping down to python 3.7 any more alternative solutions?

We have a ticket opened in eth-account to look into these issues and this is a bit older so I'm going to close this in favor of keeping the conversation there: ethereum/eth-account#132
