1. Python Errors

modulenotfounderror no module named ‘reportlab’

The Python ModuleNotFoundError: No module named ‘reportlab’ occurs when we forget to install the reportlab module before importing it or installed it in an incorrect environment. To solve the error, install the module by running the pip install reportlab command.

Open your terminal in your project’s root directory and install the reportlab module.

# 👇️ in a virtual environment or using Python 2
pip install reportlab

# 👇️ for python 3 (could also be pip3.10 depending on your version)
pip3 install reportlab

# 👇️ if you get permissions error
sudo pip3 install reportlab

# 👇️ if you don’t have pip in your PATH environment variable
python -m pip install reportlab

# 👇️ for python 3 (could also be pip3.10 depending on your version)
python3 -m pip install reportlab

# 👇️ for Anaconda
conda install -c conda-forge reportlab

The Python error “ModuleNotFoundError: No module named reportlab” occurs for multiple reasons:

  1. Not having the reportlab package installed by running pip install reportlab.
  2. Installing the package in a different Python version than the one you’re using.
  3. Installing the package globally and not in your virtual environment.
  4. Your IDE running an incorrect version of Python.
  5. Naming your module reportlab.py which would shadow the official module.
  6. Declaring a variable named reportlab which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

# 👇️ Checking version of python
python –version

For example, my Python version is 3.10.4

So I would install the reportlab package with pip3.10 install reportlab

pip3.10 install reportlab

# 👇️ if you get permissions error use pip3 (NOT pip3.X)
sudo pip3 install reportlab

Notice that the version number corresponds to the version of pip I’m using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip.

# 👇️ make sure to use your version of Python, e.g. 3.10
python3 -m pip install reportlab

If the “No module named reportlab” error persists, try restarting your IDE and development server / script.

You can check if you have the reportlab package installed by running the pip show reportlab command.

# 👇️ check if you have reportlab installed
pip3 show reportlab

# 👇️ if you don’t have pip setup in PATH
python3 -m pip show reportlab

The pip show reportlab command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

If you are using a virtual environment, make sure you are installing reportlab in your virtual environment and not globally.

You can try creating a virtual environment if you don’t already have one.

# 👇️ use correct version of Python when creating VENV
python3 -m venv venv

# 👇️ activate on Unix or MacOS
source venv/bin/activate

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ install reportlab in virtual environment
pip install reportlab

Your virtual environment will use the version of Python that was used to create it.

If the error persists, make sure you haven’t named a module in your project as reportlab.py because that would shadow the original reportlab module.

You also shouldn’t be declaring a variable named reportlab as that would also shadow the original module.

If the error is not resolved, try to uninstall the reportlab package and then install it.

# 👇️ check if you have reportlab installed
pip3 show reportlab

# 👇️ if you don’t have pip set up in PATH
python3 -m pip show reportlab

# 👇️ uninstall reportlab
pip3 uninstall reportlab

# 👇️ if you don’t have pip set up in PATH
python3 -m pip uninstall reportlab

# 👇️ install reportlab
pip3 install reportlab

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install reportlab

Try restarting your IDE and development server/script.

You can also try to upgrade the version of the reportlab package.

pip3 install reportlab –upgrade

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install reportlab –upgrade

Conclusion

The Python “ModuleNotFoundError: No module named reportlab” occurs when we forget to install the reportlab module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install reportlab command.
