Twisted Error using 'pipenv install twisted

[winrg]

Upon trying to run scrapy, I got an error. reading through it, I discovered it required twisted. I installed it using "sudo pipenv install twisted", I got this terminal out. I am doing this on a chromebook using the native debian VM.

I ha the same problem in a ubuntu 16.04 crouton on a chromebook. This stackoverflow solution worked for me: https://stackoverflow.com/questions/31457009/error-installing-twisted-for-python

I had to run the following before installing twisted: sudo apt-get install python3-dev

Install .whl file from here and make sure the c3x version of python matches
https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted

1. Install C++ Build Tools from here (only select build tools, ~3GB): https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017

2. Download wheel files from the link jess posted
   Make sure the filename matches your version of python in the (27, 33, 37) etc. (So if you have Python 3.6 and Windows 64bit, install Twisted‑19.7.0‑cp36‑cp36m‑win_amd64.whl )

3. Run pip install [wheel.whl] where you downloaded the wheel

I am having a twisted bug on OSX 10.14.6. After entering my forked directory and running pipenv install --dev --ignore-pipfile --three . I try to run scrapy genspider chi_housing "Chicago Housing Authority" http://www.thecha.org and get the error ModuleNotFoundError: No module named 'twisted'. I tried to run

pip install twisted and
pip3 install twisted outside of pipenv shell

and pipenv install twisted before going into pipenv.

All seemed to be successful but the error is still happening.

Any ideas what I should try?

hope some of this information says something about the error.

Solved the problem for Mac OSX Mojave twisted error! I think the issue had to do with me having too many versions of python on my machine and a bunch of dependencies got jumbled up. I attempted to deinstall all my versions of python and then reinstall python 3.7 by following these two links and it worked.

• https://apple.stackexchange.com/questions/284824/remove-and-reinstall-python-on-mac-can-i-trust-these-old-references

• https://stackoverflow.com/questions/3819449/how-to-uninstall-python-2-7-on-a-mac-os-x-10-6-4

Also reinstalled pipenv during the process (a licensing error came up). I am down to talk about this more if anyone else gets the same error.

SUMMARY: It had pretty much nothing to do with twisted. Seemed more to be an issue with my having weird linking and dependency stuff and I just had to delete all my python versions and reinstall the one I needed for this project.
