Modulenotfounderror: no module named ‘mock’ [SOLVED]

In this solving an error message in Python tutorial, we will learn how to solve the problem modulenotfounderror: no module named ‘mock’.

As most of us know, Python is a popular programming language that is flexible and used for developing a wide range of applications. However, we cannot avoid encountering problems while running a program.

One of these problems is the error modulenotfounderror: no module named 'mock'. So what we are going to show you here is how to solve that. But before that, you might want to know what a mock module is.

What is a mock module?

The mock module is a library in Python for testing. This module is advantageous for testing codes that depend on external libraries.

In addition to that, the mock module allows users to change parts of your code with mock objects, which imitate the primary object.

How to solve “no module named ‘mock’” in Python

The following are the steps on how to resolve the error message modulenotfounderror: no module named ‘mock’ in Python.

  1. Check if the ‘mock’ module is installed.

    The first step is to check if the mock module is installed in your Python environment. To check, open the cmd or command prompt, then type the command pip list.

    pip list command

    The command pip list will show you the list of installed modules in your Python environment. Moving on, if the mock module is not found, move to the next step.

  2. Install the ‘mock’ module.

    If the mock module is not found in your Python environment, install it. To install, input the command pip install mock.

    pip install mock - modulenotfounderror: no module named 'mock'

    The command pip install mock will download and install the latest version of the mock module in Python.

Tip: You can verify if the mock module is installed correctly by running the import mock command. However, if the same error still exists after installing it, try the following:
  • If it is correctly installed but the error still exists, try to upgrade it. To do so, input the following command:

    pip install --upgrade mock

    The command pip install --upgrade mock will upgrade the mock module to its latest version. If your mock module is already the latest version, this will come out: “requirement already satisfied.”
Note: If you get an error message stating that “pip” cannot be found, use the command python -m. It will look like this: python -m pip install mock.


In conclusion, the error modulenotfounderror: no module named ‘mock’ can be easily solved by checking if the mock module is installed in your Python environment and, if not, by installing it.

By following the guide above, there’s no doubt that you’ll be able to resolve this error quickly.
