I have just installed scrapy and all the things along with it as per from scrapy tutorial site.
When I create project using Scrapy with such command
scrapy startproject [projectname]
so it gives me following error
Traceback (most recent call last):

import OpenSSL
ImportError: No module named OpenSSL
After that even I tried to install openSSl manually using pip
but it saying that package is already installed
Help me with it.
You can satisfy the missing dependency by doing the following:
You need to install OpenSSL binaries on your system. Get binaries
from here: https://wiki.openssl.org/index.php/Binaries
Then you need to install pyOpenSSL, from here: https://pypi.python.org/pypi/pyOpenSSL/0.13

I use vscode and I'm working with Jupyter in this particular example. Yesterday, I was doing my work fine. Today, my venv is broken, so I deleted and started again:
python -m venv venv
./venv/Scripts/Activate
Okay, so I have brand new venv now. So lets try updating pip:
python -m pip --upgrade pip
And I get this error:

Okay, lets try to ignore this an set up jupyter.
pip install wheel
pip install juypterlab
pip install ipykernel
Then when I try running a cell in that notebook in VSCode I get this error:

What the heck is going on here?
Edit1
I've just proven it will error on the 3.8 global interpreter instance, even though I have other notebooks working on that. I've added a screenshot of the project.
You created a package named email, you need to rename it to some other names.
After installing:
pip install virtualenv
Running it yells:

Any ideas why this is happening ?

I've been trying to install django, looked around the internet but couldn't find possible solution for this.
I have tried looking for solutions. Some solutions told me to install conflict checker for pip but it still did not work because nothing seems to be getting installed using 'pip' keyword. It even gives me error when I try to find out my pip version
python -m pip install django

Just got the same problem.
The solution for me was to pip uninstall prompt-toolkit and pip install prompt-toolkit. This uninstalled v1.0.5 and installed v2.0.4.
I want to test weasyprint but it has a problem with the installation of pangocairo.
I successfully installed weasyprint:
pip install weasyprint
I installed gtk using this tutorial, downloading it from here.
I also set up the path to gtk\bin.
$weasyprint

I was able to solve this issue by adding this dependency. Hope this works for you as well.
sudo apt-get install -y libpangocairo-1.0-0
For Macos (M1)
even after brew install pango it shows the same error
pip uninstall weasyprint
pip install weasyprint
Hope it helps !
