You are missing flask-jwt-extended module. Get the package by running following command and then try again.
pip install flask-jwt-extended

Below is the error when I try deploy Django==3.2.12, wagtail==2.16.1, python 3.8.2, mod_wsgi 4.9 on a Debian 11 server. I have a full stack trace at the end.
class SimpleLazyObject(LazyObject):
TypeError: Error when calling the metaclass bases
'property' object is not callable
When I run this on my local dev machine which is a Mac it works just fine. I found someone with the exact same problem but no clarity about how it was resolved.
The resources I have been using to assist are 1, 2, 3, 4. I have tried installing mod_wsgi using pip and as well as from sources. Used various guides for Apache2 config. Upgraded from python 3.8 to 3.9 as well as downgraded to 3.7.
Create interpreter '0.0.0.0|'.

I had the same issue so i did the following steps:
Remove the apache2 library by using the following command-
sudo apt-get remove python-pip apache2 libapache2-mod-wsgi
Then use the following command to install the correct library-
sudo apt-get install python3-pip apache2 libapache2-mod-wsgi-py3
This solved my error.

I keep on getting the above error. I am not sure why there would be a permission error here. I checked that the file existed and wasn't empty so that's not the issue. I have looked through many tutorials on how to deploy a flask app but it never works and I think this may be why.
I followed this tutorial:https://www.youtube.com/watch?v=w0QDAg85Oow
I have two url to my application, which refers to same eg: localhost:8080 and abc.com. Pattern is that after restarting the apache server, only the first one URL works which I hit first and 2nd url does not work. Ideally both should work as both refers to same server.
I am getting below error for python 3.9. After following this I uninstalled and installed mod_wsgi 4.7.1 using python 3.9 pip and updated apache httpd.conf with output of mod_wsgi-express.exe module-config

I am trying to install nltk on an Amazon EC2 instance using pip and virtual environment. nltk is listed in the requirements.txt file that pip uses. I also want to download punkt using the nltk.download('punkt') option.
Here's what my makefile looks like:
INSTANCE_NAME=toolsapp
ENV=env
LOAD_ENV=source $(ENV)/bin/activate
VIRTUALENV_BIN:=$(shell which virtualenv || echo /usr/local/bin/virtualenv )
EB_BIN:=$(shell $(LOAD_ENV) && which eb || echo /usr/local/bin/eb )
AWS_BIN:=$(shell $(LOAD_ENV) && which aws || echo /usr/local/bin/aws )
default: dev
.PHONY: default
# Ensure virtualenv is installed
$(VIRTUALENV_BIN):
pip3 install virtualenv
# Create a virtualenv folder called env/ and install dependencies
$(ENV): $(VIRTUALENV_BIN)
virtualenv -p python3 $(ENV)
$(LOAD_ENV) && pip install --upgrade pip && pip install -r requirements.txt
But this is the error I get when I try to run the webapp:

I have recompiled python2.7.11 using:
./configure
make
make altinstall
sudo ln -s /usr/local/bin/python2.7 /usr/local/bin/python
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo /usr/local/bin/python
sudo /usr/local/bin/easy_install pip
sudo pip install virtualenv
sudo pip install virtualenvwrapper
source /usr/local/bin/virtualenvwrapper.sh
I have installed django and all the dependencies checking that the pip is located in my new python version
I uninstalled the packaged version of mod_wsgi and
I have linked mod_wsgi to the new version of python by:
./configure --with-python=/usr/local/bin/python
make install
When I restart apache both 2.7.6 and 2.7.11 seem to be started:

I am able to run the "hello world" wsgi application even though both versions of python seem to be used. However, when I use the django app I end up with an ImportError that seems to be related to the multiple versions.

make: *** [src/server/mod_wsgi.la] Error 1
Try:
make distclean
./configure --with-python=/usr/local/bin/python
LD_RUN_PATH=/usr/local/lib make
sudo make install
The LD_RUN_PATH environment variable when building embeds the directory path containing the correct library into the lookup path for the mod_wsgi.so file.
