In this article, we will learn the solutions on how to solve the modulenotfounderror no module named _cffi_backend.
Why does error occur?
The no module named ‘_cffi_backend’ occurs because the system cannot find the installed library of cffi. Also, the cause of this error is that have not installed the cffi with the used of the command pip install cffi. In other words, on your system you installed different versions of python and the cffi it doesn’t installed in an appropriate version when you are using.

How to solve the modulenotfounderror: no module named ‘_cffi_backend’
Time needed: 3 minutes
Here are the solutions to solve the no module named _cffi_backend.
- Solution 1: Install Library cffi
The most possible reason is that the Python does not provide cffi in its python standard library. You must install it first.
To solve this error, in your project root directory open command prompt(CMD). Run this following command:
“pip install cffi“ - Solution 2: Update Pip
In this command pip installs cffi in your virtual environment variable on Windows, Linux and MacOS. Make sure that your pip version is updated. If it is not, you will use this command in your project root directory, open command prompt(CMD):
“python -m pip install –upgrade pip“ - Solution 3: Install the PIP virtual environment in Python 3
This is the command to install the PIP virtual environment in Python 3:
“pip3 install cffi“
or with PIP
“python3 -m pip install cffi“ - Solution 3: Install in server side
If you have the trouble in server side. This is the following command to install in server side.
“pip install –user cffi“ - Solution 4: Install in Ubuntu
The following command to install in Ubuntu:
“sudo apt install cffi“
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.
