Application Deployment: Django is not installed on the server. AttributeError: the 'module' object does not have the 'lru_cache' attribute

Question

I am trying to deploy a Django application, and for some reason I keep getting this error. It seems to me that Django is not installed, but these are also installation errors. Thanks for the help in this. I host on Amazon EC2

Answer 1

Django has stopped supporting version 2 of Python, but you can try installing version 1.11 using the code below.

pip install Django==1.11 

Answer 2

According to the django 2.0 release notes, the Django 1.11.x series is the last to support Python 2.7 ( Check here )

So, you can use an older version of Django, and then install it with this command:

 pip install 'Django<2' 

but if you decide to create your project using Django> = 2.0, you should create a virtual environment using python 3.4 or higher:

 sudo apt-get update sudo apt-get install python3 python3-pip sudo -H pip3 install virtualenv mkdir ~/myproject cd ~/myproject virtualenv -p `which python3` myprojectenv source ~/myproject/myprojectenv/bin/activate python -V 

it should output something like this:

 Python 3.XY 

Now you can install the latest version of Django without errors:

 pip install Django 

Good luck
