Abnormal behavior of python package eve - python-3.x

Question

I have installed the eve package on my windows machine but every time I shutdown the machine and try to load the eve package I get module not found error.
On re-installation attempt(Btw I used the latest pip version to install), I get
from eve import Eve
app=Eve()
app.run()
The error points to the second line.

ModuleNotFoundError: No module named 'config'
Moreover, I find that there is no folder "lib" but "Lib". If this is the problem how do I rectify it?
However, the code below works but runs for microsecs, not like running a back-end server with api's:
from eve import Eve
app=Eve
app.run
The settings.py file:
# Let's just use the local mongod instance. Edit as needed.
# Please note that MONGO_HOST and MONGO_PORT could very well be left
# out as they already default to a bare bones local 'mongod' instance.
MONGO_HOST = 'localhost'
MONGO_PORT = 27017
MONGO_DBNAME = 'apitest'
# Enable reads (GET), inserts (POST) and DELETE for resources/collections
# (if you omit this line, the API will default to ['GET'] and provide
# read-only access to the endpoint).
RESOURCE_METHODS = ['GET', 'POST', 'DELETE']
# Enable reads (GET), edits (PATCH), replacements (PUT) and deletes of
# individual items (defaults to read-only item access).
ITEM_METHODS = ['GET', 'PATCH', 'PUT', 'DELETE']
people = {
# 'title' tag used in item links.
'item_title': 'person',
# by default the standard item entry point is defined as
# '/people/<ObjectId>/'. We leave it untouched, and we also enable an
# additional read-only entry point. This way consumers can also perform GET
# requests at '/people/<lastname>/'.
'additional_lookup': {
'url': 'regex("[\w]+")',
'field': 'lastname'
},
'cache_control': 'max-age=10,must-revalidate',
'cache_expires': 10,
'resource_methods': ['GET', 'POST'],
# Schema definition, based on Cerberus grammar. Check the Cerberus project
# (https://github.com/pyeve/cerberus) for details.
'schema': {
'firstname': {
'type': 'string',
'minlength': 1,
'maxlength': 10,
},
'lastname': {
'type': 'string',
'minlength': 1,
'maxlength': 15,
'required': True,
# talk about hard constraints! For the purpose of the demo
# 'lastname' is an API entry-point, so we need it to be unique.
'unique': True,
},
# 'role' is a list, and can only contain values from 'allowed'.
'role': {
'type': 'list',
'allowed': ["author", "contributor", "copy"],
},
# An embedded 'strongly-typed' dictionary.
'location': {
'type': 'dict',
'schema': {
'address': {'type': 'string'},
'city': {'type': 'string'}
},
},
'born': {
'type': 'datetime',
},
}
}
DOMAIN = {
'people': people,
}
So, What could be the solution to this problem?
Any help is appreciated.

I don't have this issue after a quick test. Let me share with you all steps and let me know anything is different.
1) Enter Anaconda Prompt
2) conda create -n eswar python=3.6
3) conda activate eswar
4) pip install eve
5) python
5.1) import eve
5.2) exit()
6) shutdown windows machine
7) restart windows machine
8) enter anaconda prompt
9) conda activate eswar
10) python
11) from eve import Eve
12) everything looks fine.
did you forget to activate your env after restart?
