When I use "pip install" to install scrapy for Python on Windows, I request this feedback:
Exception:
Traceback (most recent call last):

I know it maybe a coding problem, but I don't know how to solve it.
Who can help me?
Thanks.
Scrapy runs on Python 2.7 and Python 3.3 or above (except on Windows where Python 3 is not supported yet).
Sorry to be the bearer of bad news. It's worth a chance to use Anaconda, which is also stated in the Scrapy docs, if you're particularly hell bent on using Python 3.6. Or if it's urgent, you can use Python 2.7 and pip install scrapy. From my experience, Python 2.7 works a lot better when in comes to Scrapy.

I am working on jupyterhub and have tried creating a conda environment with Python version 3.7 as suggested in other cases, but the problem was not solved.
Any tips are welcome!
The problem comes from the encodage.
I think these topics could help you.

In general google your error message you'll find o lot of related post and maybe your answer.
With no system changes, just a reboot, my raspberry pi (buster) python 3.7 installation does this when the python3 command is run:

I'm unable to uninstall python using apt-get because that same error gets thrown partway through the uninstall process.
Any idea how to fix the error, or remove python so I can re-install it?
For future users: It looks like the SD card on the pi is dying. I managed to get python semi-working by copying a working python directory for another raspberry pi, but apt-get source files were corrupted as well. Managed to get my working files off, but a new SD card is required.
I tried to install anaconda 2.7 on my new computer(running win10), but failed.
I had it installed on my old laptop (running win7), and I was using spyder happily. Now after the install, the Navigator refuses to open, and the anaconda prompt gives an error first hand when opening.
The error i am receiving:

I tried reinstalling anaconda completely, tried both 64 and 32 bit versions, tried miniconda, same error all the time.
Would really appreciate any help!
Seems to be related to non-utf-8 characters in your home directory.
See a similar issues for 'ascii' codec:

If you need to use Python 2 it is suggested to use Anaconda3 and create a Python 2 environment from that.

I googled around and it supposed to be a locale error, I managed to set locale to en_us.utf-8 it didn’t change anything. I don’t understand much about these settings, so I don’t know what to do next.
Could anybody help me out with this?
The package name is AllAuth and it fails with any version, new old, everything fails.
Try this executing
export PYTHONIOENCODING=utf8
try this link. Might be helpful for you.
Make sure that the package you're trying to install is Python 2 compatible. More and more modules are migrated to Python 3 and the new version handles unicode characters differently than version 2.

The OSMnx installation instructions suggest using conda-forge to install. This is particularly important on Windows, as you want to avoid compiling all the C extensions required by the geospatial dependencies.
conda install -c conda-forge osmnx
Or if all else fails, do the install in a nice clean virtual environment:
conda create --yes -c conda-forge -n OSMNX python=3 osmnx
source activate OSMNX
That should solve any Windows-related install problems (and works for Mac and Linux too).
