Одна распространенная ошибка, с которой вы можете столкнуться при использовании Python:
no module named ' matplotlib '
Эта ошибка возникает, когда Python не обнаруживает библиотеку matplotlib в вашей текущей среде.
В этом руководстве представлены точные шаги, которые вы можете использовать для устранения этой ошибки.
Шаг 1: pip устанавливает matplotlib
Поскольку matplotlib не устанавливается автоматически вместе с Python, вам нужно будет установить его самостоятельно. Самый простой способ сделать это — использовать pip , менеджер пакетов для Python.
Вы можете запустить следующую команду pip для установки matplotlib:
pip install matplotlib
В большинстве случаев это исправит ошибку.
Шаг 2: Установите пип
Если вы все еще получаете сообщение об ошибке, вам может потребоваться установить pip. Используйте эти шаги , чтобы сделать это.
Вы также можете использовать эти шаги для обновления pip до последней версии, чтобы убедиться, что он работает.
Затем вы можете запустить ту же команду pip, что и раньше, чтобы установить matplotlib:
pip install matplotlib
На этом этапе ошибка должна быть устранена.
Шаг 3: проверьте версии matplotlib и pip
Если вы все еще сталкиваетесь с ошибками, возможно, вы используете другую версию matplotlib и pip.
Вы можете использовать следующие команды, чтобы проверить, совпадают ли ваши версии matplotlib и pip:
which python
python --version
which pip
Если две версии не совпадают, вам нужно либо установить более старую версию matplotlib, либо обновить версию Python.
Шаг 4: Проверьте версию matplotlib
После того, как вы успешно установили matplotlib, вы можете использовать следующую команду, чтобы отобразить версию matplotlib в вашей среде:
pip show matplotlib
Name: matplotlib
Version: 3.1.3
Summary: Python plotting package
Home-page: https://matplotlib.org
Author: John D. Hunter, Michael Droettboom

Error code:
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
I tried:
python -m pip install -U pip
python -m pip install -U matplotlib
didn’t work.
and then I tried:
pip install --upgrade setuptools
didn’t solve the problem.
I read on SO that maybe if I open the shell in administrator mode it could solve the problem but it didn’t work too.
I saw someone mentioning ez-setup for this error code. I installed it but that didn’t work too.
I don’t know if it has something to do but my C directory looks like this:
C:UsersMETİNUSTA
It has an uppercase i character which sometimes can cause problems with applications. I can’t change it because I am using my school’s Windows key and it don’t let me do any change. Because of this I installed python on D: .
Also here my pip list for extra information:
ez-setup 0.9
flake8 3.8.4
mccabe 0.6.1
pip 20.2.4
pycodestyle 2.6.0
pyflakes 2.2.0
setuptools 50.3.2

Does python look for matplotlib in different locations?
The environment is:
- Mac OS X 10.8.4 64bit
- built-in python 2.7
numpy, scipy, matplotlib is installed with:
sudo port install py27-numpy py27-scipy py27-matplotlib
py27-ipython +notebook py27-pandas py27-sympy py27-nose
The error “ModuleNotFoundError: No module named matplotlib» is a common error experienced by data scientists when developing in Python. The error is likely an environment issue whereby the matplotlib package has not been installed correctly on your machine, thankfully there are a few simple steps to go through to troubleshoot the problem and find a solution.
Your error, whether in a Jupyter Notebook or in the terminal, probably looks like one of the following:
No module named 'matplotlib'ModuleNotFoundError: No module named 'matplotlib'
In order to find the root cause of the problem we will go through the following potential fixes:
- Upgrade pip version
- Upgrade or install matplotlib package
- Check if you are activating the environment before running
- Create a fresh environment
- Upgrade or install Jupyer Notebook package
Are you installing packages using Conda or Pip package manager?
It is common for developers to use either Pip or Conda for their Python package management. It’s important to know what you are using before we continue with the fix.
If you have not explicitly installed and activated Conda, then you are almost definitely going to be using Pip. One sanity check is to run conda info in your terminal, which if it returns anything likely means you are using Conda.
Upgrade or install pip for Python
First things first, let’s check to see if we have the up to date version of pip installed. We can do this by running:
pip install --upgrade pip
Upgrade or install matplotlib package via Conda or Pip
The most common reason for this error is that the matplotlib package is not installed in your environment or an outdated version is installed. So let’s update the package or install it if it’s missing.
For Conda:
# To install in the root environment
conda install matplotlib
# To install in a specific environment
conda install -n MY_ENV matplotlib
For Pip:
# To install in the root environment
python3 -m pip install -U matplotlib
# To install in a specific environment
source MY_ENV/bin/activate
python3 -m pip install -U matplotlib
Activate Conda or venv Python environment
It is highly recommended that you use isolated environments when developing in Python. Because of this, one common mistake developers make is that they don’t activate the correct environment before they run the Python script or Jupyter Notebook. So, let’s make sure you have your correct environment running.
For Conda:
conda activate MY_ENV
For virtual environments:
source MY_ENV/bin/activate
Create a new Conda or venv Python environment with matplotlib installed
During the development process, a developer will likely install and update many different packages in their Python environment, which can over time cause conflicts and errors.
Therefore, one way to solve the module error for matplotlib is to simply create a new environment with only the packages that you require, removing all of the bloatware that has built up over time. This will provide you with a fresh start and should get rid of problems that installing other packages may have caused.
For Conda:
# Create the new environment with the desired packages
conda create -n MY_ENV python=3.9 matplotlib
# Activate the new environment
conda activate MY_ENV
# Check to see if the packages you require are installed
conda list
For virtual environments:
# Navigate to your project directory
cd MY_PROJECT
# Create the new environment in this directory
python3 -m venv MY_ENV
# Activate the environment
source MY_ENV/bin/activate
# Install matplotlib
python3 -m pip install matplotlib
Upgrade Jupyter Notebook package in Conda or Pip
If you are working within a Jupyter Notebook and none of the above has worked for you, then it could be that your installation of Jupyter Notebooks is faulty in some way, so a reinstallation may be in order.
For Conda:
conda update jupyter
For Pip:
pip install -U jupyter
Best practices for managing Python packages and environments
Managing packages and environments in Python is notoriously problematic, but there are some best practices which should help you to avoid package the majority of problems in the future:
- Always use separate environments for your projects and avoid installing packages to your root environment
- Only install the packages you need for your project
- Pin your package versions in your project’s requirements file
- Make sure your package manager is kept up to date
