How to Fix: No module named pandas

One common error you may encounter when using Python is:

no module name 'pandas'

This error occurs when Python does not detect the pandas library in your current environment.

This tutorial shares the exact steps you can use to troubleshoot this error.

Step 1: pip install pandas

Since pandas doesn’t come installed automatically with Python, you’ll need to install it yourself. The easiest way to do so is by using pip, which is a package manager for Python.

You can run the following pip command to install pandas:

pip install pandas

In most cases, this will fix the error.

Step 2: Install pip

If you’re still getting an error, you may need to install pip. Use these steps to do so.

You can also use these steps to upgrade pip to the latest version to ensure that it works.

You can then run the same pip command as earlier to install pandas:

pip install pandas

At this point, the error should be resolved.

Step 3: Check pandas and pip Versions

If you’re still running into errors, you may be using a different version of pandas and pip.

You can use the following commands to check if your pandas and pip versions match:

which python
python --version
which pip

If the two versions don’t match, you need to either install an older version of pandas or upgrade your Python version.

Step 4: Check pandas Version

Once you’ve successfully installed pandas, you can use the following command to display the pandas version in your environment:

pip show pandas
