ModuleNotFoundError: No module named 'flask_mysqldb' even if installed - python

I'm using mysql with flask for developing a basic website and I'm getting ModuleNotFound error even if I have the module installed. Can someone solve this ?

This a common python path issue, to make sure it isn't your case, type :
import sys
print(sys.path)
and check if it contains:
/usr/local/lib64/python3.6/site-packages
The problem is that you install the package using pip somewhere, and you're trying to import it from somewhere else where it's not installed. The trick to solve it is by running this command :
export PYTHONPATH=$PYTHONPATH:/path/to/your/modules

It still shows the same after I restarted the kernel and even reinstalled the firebase module.

When I run
os.getcwd()
in spyder/python, I get
'C:\\Users\\MBSanders'
My question is, why do I get
ModuleNotFoundError: No module named 'geocoder'
When I run
import geocoder
I'm somewhat new to python. Please let me know if additional info is needed to trouble shoot. I'm within a federal agency so I do not have admin rights.
When I run sys.path in the console, I get
sys.path

Assuming you're running python on the terminal, and python is the command you're using to run it, try doing python -m pip install geocoder. That'll install it for the python build you want to use. Or if you know the full path to the python build you're using, you can do something similar like /path/to/python -m pip install geocoder.

if you are using python 3.7 or 3.8 you may need to pip3.7 or pip3.8 install if you OS is recognizing a 2.x version as default

ImportError: No module named flask_toastr

I want to use Toastr, for showing non-blocking notifications in my Flask app. I already installed the package with pip :
sudo pip install Flask-Toastr
Here is the output of the installation

Here is theimport statement:
from flask_toastr import Toastr
But when I run my script I have this ImportError. How can I fix this? Thank you

Without seeing your import statement I suspect you have used a '-' instead of an underscore in the import statement:
Try this:
from flask_toastr import Toastr
