I use the Mac terminal to check my package:
pip list
I can find all packages including Pandas:
But when I
import pandas
it told me:
ModuleNotFoundError: No module named 'pandas'
By the way, I have Python 2 and Python 3 on my Mac. They are not the same directory, and I suspect the Python interpreter didn't find the path of Pandas.
First of all, install virtualenv inside your project folder to secure your project directory to avoid conflict with your other packages.
pip install virtualenv
After installing this, run this command one by one inside your root project directory:
virtualenv venv
source venv/bin/activate
Now your directory is secure and you can install your required packages inside.
pip install pandas
and others as you required.
Because you have installed virtualenv and running as secure, it will not conflict with other outside packages.
Use these all steps one by one.
Try to install Pandas using pip and pip3:
pip install pandas
pip3 install pandas
A suggestion: Use pyenv and set a Python version for your local directory.
If Python 2.7 is already installed, then to install NumPy and Pandas for v2.7, run the below commands:
For Ubuntu / Linux -
sudo apt-get install python-numpy
sudo apt-get install python-pandas
If Python 3 is already installed, then to install NumPy and Pandas for v3, run the below commands:
For Ubuntu / Linux -
sudo apt-get install python3-numpy
sudo apt-get install python3-pandas
I had Python 2 and Python 3 installed in different directories, but I was facing this error, because when I was using the command pip install pandas, it was installing Pandas in Python 2 directories while I was using Python 3.
So I had two directories with Python2 --> C:\Python27 and Python365 --> C:\Python365.
To resolve this error:
Run pip install pandas in cmd. If library Pandas is already installed, you'll see something like the following.
pip install pandas
Requirement already satisfied: pandas in c:\python27\lib\site-packages (0.23.4)
Requirement already satisfied: python-dateutil>=2.5.0 in c:\python27\lib\site-packages (from pandas) (2.7.3)
Requirement already satisfied: numpy>=1.9.0 in c:\python27\lib\site-packages (from pandas) (1.14.4)
Requirement already satisfied: pytz>=2011k in c:\python27\lib\site-packages (from pandas) (2018.4)
Requirement already satisfied: six>=1.5 in c:\python27\lib\site-packages (from python-dateutil>=2.5.0->pandas) (1.11.0)
From the output of above command you can see that pandas is installed in the Python2 directory, i.e. C:\python27\lib\site-packages (0.23.4).
Run the python command in cmd to check which Python version are you running.
python
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
You can see that I'm using Python3 while Pandas is installed in the Python2 directory.
To install Pandas and other libraries in Python3 go to the scripts folder in Python3 directory, i.e., C:\Python365\Scripts.
Open a Command window and run pip install pandas.
Or you can use the complete path of pip in the Python3 directory in cmd to run the install command, i.e., C:\Python365\Scripts\pip install pandas
Sometimes, it might be due to an issue with Microsoft Visual C++.
For that, first you need to install Microsoft Visual C++ using the instructions given in Error "Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)"
After successful installation, use pip install pandas to install Pandas
If pip is not installed, then download the Pandas source package with extension tar.gz and place it in directory wherever you want after extracting. Open cmd.exe and navigate to the path where the Pandas folder is extracted & placed using cd C:/pandas. Then install it using the python setup.py install
Finally you should get the success message as
Finished processing dependencies for pandas==0.xx.0
I tried almost every suggestion under this question, but I still faced the issue and after a lot of struggle, I resolved this by the below steps.
Run the command prompt as administrator and then enter the below.
pip install pandas
It helps you resolve the issue.
The error I saw was:
File "c:\SIP\python\visualws\learn1\pandas_test.py", line 6, in import pandas as pd ModuleNotFoundError: No module named 'pandas'
I executed the below command in Windows using Python 3.9.5:
pip install pandas

It solved the problem and I was able to execute the .py file with import pandas.
