Understanding the No module named bs4 error
Let us now understand what does ModuleNotFoundError: No module named bs4 error means. In Python, we get a lot of useful information from such errors. They usually have two main parts which help us to figure out the problem. The first part of the error represents the category of the error which in our case is ModuleNotFoundError. The error means we are trying to import some module that does not exist on our system. The reason can be either the module is not installed or we have a typo error.
The second part of the error gives more specific information about the error. It helps us to understand and figure out which module is not imported. For example, in our case, it clearly says the module named bs4 does not exist.
What is ModuleNotFoundError in Python?
As we discussed the ModuleNotFoundError in Python means the module we are trying to import does not exist on our system. The reasons for this error can be:
- The module is not installed
- We have a typo error while writing the name of the module.
Let us take an example and see why we are getting this error. Let us assume that we have a Python file named module.py in the same directory. We can use this file to understand the ModuleNotFoundError. Let us try to import the module:
# importing the module import Module
This will raise the following error:
--------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) /tmp/ipykernel_350714/1689267883.py in <module> 1 # importing the module ----> 2 import Module ModuleNotFoundError: No module named 'Module'
The reason for getting this error is the typo mistake. The name of the library is a module, not a Module.
What is bs4 in Python?
