启动测试服务器时无法导入Django

Question

When running the command:

python manage.py runserver

To launch a test server, I get the following error:

ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

Steps I took to get this error:

1) I downloaded the Django project from my Linux VPS (without the virtual environment). I am using Windows 10 on this current system.

2) I created a new virtual environment in that folder using:

virtualenv myprojectenv

3) The env was created successfully, I now have the following folders/files:

myproject myprojectenv static manage.py

4) I activate the env ( myprojectenv\\scripts\\activate ), success - my commandline changes to

(myprojectenv) C:\\ (path to my folder)

5) I install Django using

pip install django

Django successfully installed, when checking the version, it returns 2.1.1:

python -c "import django; print(django.get_version())
2.1.1

6) I go back to the main dir where manage.py is, I try to run the test server with

python manage.py runserver

And I get the error (specified above). So, what have I done wrong here? I have the env folder correctly in that directory, Django installed. It still can't find it.

I thought the problem may be with my Django files, but no. When I start a new project from the myprojectenv env using

django-admin startproject mysite

The mysite folder gets created - I go into that folder (where manage.py is) and I try to launch the test server again. It still can't find Django! Any help is appreciated.
