在Python 3.6.2上部署Django

Question

I have downloaded Python 3.6.2 (64 bit) in Windows 10 (64 bit). Now I want to work on Django framework so I want to download Django using pip command but it shows Error.

C:\Windows\system32>pip install django
Collecting django
  Using cached Django-1.11.4-py2.py3-none-any.whl
Collecting pytz (from django)
  Using cached pytz-2017.2-py2.py3-none-any.whl
Installing collected packages: pytz, django

Exception:

Answer 1

The problem has to do with the location you have chosen to install python, normally it's installed in C:\\pythonXX but your installation is in C:\\Program Files\\pythonXX. That is always going to cause problems, you will need to always be running it as administrator. Quick and best solution, uninstall and accept to install python on the default location - C:\\pythonXX

The best way to work with Django is within a virtual environment. Installing packages in your system's Python 3.6 will affect all programs you have running on Python 3.6; if you have multiple Django apps, your requirements could get all mixed up.

Django works really nicely with virtual environments: there's a good tutorial here . Essentially, you want to set up a virtual environment for each project, and then install Django (and its dependencies) cleanly within that environment. This should avoid any "Access denied" or other errors that you're experiencing.

Just as an example of how virtual environments help: if you need to use different versions of Django for different apps, they should be limited only to apps within that same virtual environment. Then, you can install the package differently in a different environment for another app. That way, when you "import django" from one of your apps, you know you're getting the version you need.
