![Modulenotfounderror: no module named 'aws_cdk' [SOLVED]](https://itsourcecode.com/wp-content/uploads/2023/03/modulenotfounderror-no-module-named-aws_cdk.png)
Have you ever encountered an error in Python that states modulenotfounderror: no module named ‘aws_cdk’ in the past?
If yes, we are confident you know how to solve this error.
However, if you are encountering it now, stop worrying and continue reading.
In this article, we will show you how to solve the mentioned error that most developers encounter.
This error indicates that the essential AWS CDK (Cloud Development Kit) package is not installed on your system or Python environment.
What is Python?
Python is one of the most popular programming languages.
It is used for developing a wide range of applications.
In addition, Python is a high-level programming language that is used by most developers due to its flexibility.
Returning to our issue, we must take a few actions to fix this error.
So, without further ado, here is how to fix this problem.
How to solve “no module named ‘aws_cdk’” in Python
Here’s how to resolve the error message stating modulenotfounderror: no module named ‘aws_cdk’ in Python.
- Install the AWS CDK package.
Resolving the error modulenotfounderror: no module named ‘aws_cdk’ is an easy task.
All you have to do is install the AWS CDK package.
To install this package, open your cmd or command prompt, then input the command pip install aws-cdk.core.
The command pip install aws-cdk.core will download and install the AWS CDK package on your system. - Import.
You can now import it into your code if the installation was successful.
To do so, input: import aws_cdk.core.

Tip: Before installing or using the AWS CDK package, activate your virtual environment if you’re using one.
However, if you’re using an IDE or editor, be sure that it is using the appropriate Python interpreter and has the AWS CDK package installed.
Installing the AWS CDK package on Jupyter Notebook:
If you’re using Jupyter Notebook, input the command:
!pip install aws-cdk.coreThen, run it.
Commands you might need
- pip list
This command will display all the packages installed on your system, including their versions.
If you’re using Jupyter Notebook, use the !pip list command instead of pip list.
However, if you’re using Anaconda, use the command conda list.
- python -m
Include this command in your pip install aws-cdk.core command if you get an error message stating that “pip” cannot be found.
Example: python -m pip install aws-cdk.core
However, if you’re using Python 3, use the command python3 -m pip install aws-cdk.core instead of python -m pip install aws-cdk.core.
- pip install –upgrade pip
Use this command to upgrade the pip package manager to its newest version.
If your pip is already in the latest version, this will come out: “Requirement already satisfied.”
- python –version
Use this command if you want to check what version of Python you have.
- pip show aws-cdk.core
Use this command to display information about your aws-cdk_core module, including its location.
If you’re using Jupyter Notebook, use the command !pip show aws-cdk.core instead of pip show aws-cdk.core.
- pip install –upgrade aws-cdk.core
Use this command to upgrade your aws-cdk.core module to its latest version.
If it is already the latest version, this will come out: “Requirement already satisfied.”
If you’re using Jupyter Notebook, use the command !pip install –upgrade aws-cdk.core instead of pip install –upgrade aws-cdk.core.
Frequently Asked Questions
What is Python ModuleNotFoundError and what causes it?
ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.
How do I fix ‘ModuleNotFoundError: No module named X’?
Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.
Why does my code work in one environment but not another?
Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.
Is ModuleNotFoundError the same as ImportError?
ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.
Where can I find more ModuleNotFoundError fixes?
Browse the ModuleNotFoundError reference hub for 198+ specific module fixes (TensorFlow, Flask, Django, pandas, numpy, etc.). For related issues see ImportError. For broader Python setup see Python Tutorial hub.
Conclusion
In conclusion, the error modulenotfounderror: no module named ‘aws_cdk’ can be easily solved by:
“Checking if the AWS CDK package 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.
We hope you’ve learned a lot from this.
