Readme WSGI example doesn't find the correct folder

[checor]

Hello,

Trying to run the WSGI example on readme doesn't work when runned in any other folder than the one the .env lives.

For example, having a folder with a .env a file named main.py:

import os
import dotenv

print("Loading file:", os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env'))
dotenv.read_dotenv(os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env'))

Running on the same folder works without problems:

$ python main.py
Loading file: .env

Moving to another folder, fails:

$ python path/to/main.py
Loading file: .env
dot_env_example/main.py:5: UserWarning: Not reading .env - it doesn't exist.
  dotenv.read_dotenv(os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env'))

This can be avoided removing the duplicated os.path.dirname part:

 $ python path/to/main.py
Loading file: path/to/.env

Is the parameter supposed to be entered relative to the main.py folder, or relative to the folder being run?

Cheers!

I just ran into this issue in my own environment.

Changing
dotenv.read_dotenv(os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env'))

to
dotenv.read_dotenv(os.path.join((os.path.dirname(__file__), '.env'))

is what fixed the problem for me.

Hope this helps!
