I'm using Windows 11, Python 3.10.1. I created a virtual environment using venv, and installed scrapy, and all requirements. Everything worked perfectly! Then I installed Python 3.11.1, created a virtual environment using venv, installed scrapy, and I received an error:
Building wheel for twisted-iocpsupport (pyproject.toml) ... error
error: subprocess-exited-with-error

Issue of concern
I already had Microsoft Visual C++ 14.0 installed on my device, and I was able to run scrapy 2.7.1 successfully using Python 3.10. I only experienced this issue with Python 3.11.
Mitigation attempts
Installed a fresh copy of Microsoft Visual C++ 14.0 from the website ~ No resolve. ❌
Uninstalled, reinstalled Python 3.11 ensuring PATH was installed ~ No resolve. ❌
Created a virtual environment using pipenv, and Python 3.11. Same error as using venv ~ no resolve. ❌
Created a virtual environment using venv, and Python 3.10 ~ Scrapy works! ✅
Created a virtual environment using pipenv, and Python 3.10 ~ Scrapy works! ✅
So it seems like this is specific to Python 3.11 perhaps. So, right now I am back to using Python 3.10 for Scrapy projects.
Question
How can I resolve this issue, and use Python 3.11 for Scrapy projects?
Getting errors when installing scikit-image with python-3.11.0.
The package is simply installed via pip install scikit-image or python -m pip install -U scikit-image.
The error messages showed that the problem occur on the wheel building process, and therefore hinder the scikit-image installation. How could I fix this problem?

Two approaches were suggested:
Downgrades to an older python version:
Nathan answer
Install Visual Studio C++ compiler, as mentioned in: https://wiki.python.org/moin/WindowsCompilers
However, I would like to stay on current python version, and I'm getting stuck in the second approach.
In my case, this problem was solved via installing a wheel file from:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-image
In my case, I download the cp311 windows amd64 version.
Then, install the .whl file to the virtual environment
(env) D:\env>python -m pip install D:\Download\scikit_image-0.19.3-cp311-cp311-win_amd64.whl
Finally, the scikit-image was successfully installed.

All steps to install build tools:
1. Download build tools
2. Download layout files for offline installation:
possible workloads are specified here. Following command contains workloads for msbuild and C++ build tools.
3. Run (exe file will have some version numbers in name):
vs_BuildTools.exe --layout c:\BT2017offline
--add Microsoft.VisualStudio.Workload.MSBuildTools
--add Microsoft.VisualStudio.Workload.VCTools
--add Microsoft.VisualStudio.Workload.WebBuildTools
--add Microsoft.VisualStudio.Workload.NetCoreBuildTools --lang en-US
4. Copy c:\BT2017offline to box on which you want to install it.
5. Open mmc and import all certificates from c:\BT2017offline\certificates to "Trusted Root Certification Authorities" of computer (not current user)
6. Run (exe file will have some version numbers in name):

i was have same problem
my config was : python==3.7 django==2.2 pip==19.0.3
and its not from pycharm
its from pip
just upgrade pip to 21.0.1
Update:
some error code:
running build_rust
=============================DEBUG ASSISTANCE=============================
If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation.html for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq.html
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation.html#rust
5) If you are experiencing issues with Rust for *this release only* you may
set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

However, after many trials, this method doesn't seem to work and I am getting the following error on the terminal.

You can try to install cmake.
pip install cmake
I also had an issue with the latest QISKit. Kindly check the issue at the github page QIS Issue 292.
