无法在macOS Sierra上使用Python3导入Django

Question

Have both versions of Python (Legacy 2.7.10 and 3.6.2) installed on macOS Sierra.

Installed pip using the following steps.

Downloaded it using curl:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Installed pip it by running the installer script:

sudo python get-pip.py

Checked for any upgrades / updates for pip:

sudo pip install -U pip

Installed django 1.11:

sudo pip install django==1.11

When I run python (legacy):

python
Python 2.7.10 (default, Feb  7 2017, 00:08:15) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> print(django.get_version())
1.11

However, when trying it using python3:

python3
Python 3.6.2 (v3.6.2:5fd33b5926, Jul 16 2017, 20:11:06) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'django'

Note: I followed a different tutorial and got python3 working with django 1.11 using virtualenv - please don't suggest this as I am new to the python world and just want to use python3 / django 1.11 in a non-virtual environment - I just want have it working like the legacy python interpreter is behaving.

pip installs libraries differently for python2 and python3, so you effectively have different environments for each. If you want to install Django for python3, you'll want to install it like this:

pip3 install django==1.11
