Python ConfigParser won't run from command line

Python script runs successfully within IDE, but has ConfigParser error when attempted to run via command line.

The error:

raise NoOptionError(option, section) ConfigParser.NoOptionError: No option 'password' in section: 'database'

The code:

from ConfigParser import SafeConfigParser

parser = SafeConfigParser()
parser.read('settings.ini')

# sets database and API configuration from settings.ini

API_KEY = parser.get('tokens','api_key')

db_user = parser.get('database','user')
db_pwd = parser.get('database','password')
db_host = parser.get('database','host')
db_database =  parser.get('database','database')

Path and Environment appear to be fine, so the issue seems to be with ConfigParser. Any thoughts on what might be wrong? To re-iterate, the script runs fine from within the IDE (when using Spyder, PyCharm, etc.). Environment is pointing to Anaconda, as anticipated.

Many thanks for help.

Rob (in comments) got me on the right track. The issue is that Python had a different working directory than the script expected. To make the script work, I added:

import sys
import os

os.chdir(os.path.dirname(sys.argv[0]))

... and it works. Thank you everyone for the help - very much appreciated.

Your import target is incorrect. The module name is "configparser" (case-sensitive.) The IDEs you mentioned probably perform some start-up initialization that masks the error.
