title: Django 'DIRS': [] in settings.py TEMPLATES causes "TemplateDoesNotExist" Error
body: <p>I'm using django version 2.1.2 with python 3.6.</p>
  
  <p>I created two django projects (test01 &amp; test02) by CMD.
  Both of the projects are under the same folder.
  Test01 executes normally, while test02 raises TemplateDoesNotExist error.  <a href="https://i.stack.imgur.com/te26V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/te26V.png" alt="enter image description here"></a></p>
  
  <p>I've found a solution for the latter that is hard coding the address of templates in settings.py: </p>
  
  <p>'DIRS': [r'C:\django\test02\accounts\templates']</p>
  
  <p>However, another project can run normally even leaving this list as blank [].</p>
  
  <p>The structures of both projects are the same:

  <p>Can anyone give a suggestion that can fix the problem in test02 without hard coding the address of templates in test02?</p>
