Why a .pth file is created sometime on package installation?












0















Sometime, when I install a package, I can notice that a .pth file has been created in the site-packages dir just at the same level as the package code. For example, if I do a



pip install DjangoDevKit


I can see in site-packages directory :



djangodevkit                        (a directory)
DjangoDevKit-1.0.7.dist-info (a directory)
DjangoDevKit-1.0.7-py3.5-nspkg.pth


The .pth file contains:



import sys, types, os;p = os.path.join(sys._getframe(1).f_locals['sitedir'], *('djangodevkit',));ie = os.path.exists(os.path.join(p,'__init__.py'));m = not ie and sys.modules.setdefault('djangodevkit', types.ModuleType('djangodevkit'));mp = (m or ) and m.__dict__.setdefault('__path__',);(p not in mp) and mp.append(p)


How this DjangoDevKit-1.0.7-py3.5-nspkg.pth has been created ?
The setup.py does not tell to create such a .pth file. I searched into the code but there is nothing obvious.



Do you have an idea ?

          DjangoDevKit is a namespace package. That's why setuptools created *_nspkg.pth.
