I have a python project working fine in Aptana.
I then started to use pipenv for the project's environment management and now I can't get Aptana to use that environment.
I also set up a new project then added it to Aptana and Aptana uses a 3.7 version of python instead of the pipenv python 2.7.
Any suggestions on where to start looking?
Pipenv and python folders
Get the location where pipenv is storing the virtual environment with:
pipenv --venv
It will return a folder: [environment_folder]
Also, get at hand the location of the original python executable, the one used by pipenv: [python_folder]
Eclipse configuration
Go to the existing project where you want to use pipenv or create a new python project.
Go to Eclipse menu: Project > Properties
Choose: PyDev - Interpreter
Click:  "Click here to configure an interpreter not listed"
Choose "New" from python interpreter
Use the environment_folder output of pipenv --venv
Set Interpreter Executable to: [environment_folder]\Scripts\python.exe
When propmted, select folders to add to system PYTHONPATH:

[python_folder]\Lib
[python_folder]\DLLs
[environment_folder]\
[environment_folder]\lib [environment_folder]\Scripts
[environment_folder]\lib\site-packages

Add those folders.
Accept and apply.
And everything should be ready.
How do I configure Aptana IDE (Eclipse) to work with pipenv?
