[SOLVED] Modulenotfounderror: no module named cryptography

In this article, we will give the solutions to the error encountered of many programmers which is the no module named ‘cryptography’.

Why does modulenotfounderror: no module named ‘cryptography’ occur?

The error usually occur if you are forget to install the “cryptography” or the python interpreter cannot find the installed library for cryptography.

Moreover, the error no module named cryptography occurs because you may have installed different versions of python in your system.

The cryptography doesn’t install in specific version you are using.

Conception of the Problem

You have just studied the amazing prospects of the cryptography module and you wanna try it out. First, you need to start with the following program:

import cryptography

This is to assume to import the module library into your virtual environment variable. Yet, the error message occurs with the following ModuleNotFoundError: No module named ‘cryptography’:

>>> import cryptography
Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    import cryptography
ModuleNotFoundError: No module named 'cryptography'

How to fix the modulenotfounderror: no module named ‘cryptography’?

Time needed: 5 minutes

To fix the modulenotfounderror: no module named ‘cryptography’ by installing the module through executing the command pip install cryptography. In your project folder directory, open the command prompt(CMD) and install the cryptography package.

Solution 1: Install cryptography module in Python 2
This is the command to install the cryptography in Python 2:
pip install cryptography
Solution 2: Install cryptography module in Python 3
This is the command to install the cryptography in Python 3:
pip3 install cryptography
Solution 3: Install for server-side
If you get an error on the server side. Type this command to install:

For Linux:
sudo pip3 install cryptography

or

For windows:
pip install cryptography --user
Solution 4: Install Pip in your Path Virtual Environment
Make sure you installed the pip version and it is updated. If not, type the following command to install the pip with the cryptography:

For Python 2:
python -m pip install cryptography

For Python 3:
python3 -m pip install cryptography
Solution 5: Install cryptography in py alias
This is the command for the installation in cryptography in py alias:
py -m pip install cryptography
Solution 6: Install cryptography in Anaconda
This is the command for the installation in cryptography in anaconda:
conda install -c anaconda cryptography
Solution 7: Install in Jupyter Notebook
This is the command for the installation of cryptography in Jupyter Notebook:
!pip install cryptography
Solution 8: Install in Ubuntu
This is the command for the installation of cryptography in Ubuntu:
sudo apt install cryptography

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.
