The LlamaIndex Python library is a mind-blowing 
tool that lets you easily access large language models (LLMs) from your Python applications.
Overview
LlamaIndex is a powerful tool to implement the “Retrieval Augmented Generation” (RAG) concept in practical Python code. If you want to become an exponential Python developer who wants to leverage large language models (aka. Alien Technology) to 10x your coding productivity, you’ve come to the right place.
In this tutorial, I’ll show you how to install it easily and quickly so you can use it in your own Python code bases.

pip install llama-index
Alternatively, you may use any of the following commands to install llama-index, depending on your concrete environment. One is likely to work!
pip install llama-indexpip3 install llama-indexpython -m pip install llama-index python3 -m pip install llama-indexsudo pip3 install llama-index pip3 install llama-index --usersudo apt install llama-indexpyaliaspy -m pip install llama-indexconda install -c anaconda llama-index!pip install llama-index!pip3 install llama-index
This will also install third-party dependencies like OpenAI; one PIP command to rule them all!
However, when using it in your own code, you’d use the lines:
import llama_index # not: llama-index # or from llama_index import VectorStoreIndex, SimpleWebPageReader
Let’s dive into the installation guides for the different operating systems and environments!
How to Install Llama Index on Windows?
To install the updated llama-index framework on your Windows machine, run the following code in your command line or Powershell:
python3 -m pip install --upgrade pippython3 -m pip install --upgrade llama-index
Here’s the code for copy&pasting:
python3 -m pip install --upgrade pip python3 -m pip install --upgrade llama-index
I really think not enough coders have a solid understanding of PowerShell. If this is you, feel free to check out the following tutorials on the Finxter blog.

How to Install Llama Index in PyCharm?
The simplest way to install llama-index in PyCharm is to open the terminal tab and run the pip install llama-index command.
This is shown in the following code:
pip install llama-index
Here’s a screenshot of the two steps:
- Open Terminal tab in Pycharm
- Run
pip install llama-indexin the terminal to install Llama Index in a virtual environment.
As an alternative, you can also search for llama-index in the package manager. Easy peasy. 
How to Install Llama Index in Anaconda?
You can install the Llama Index package with Conda using the command conda install -c anaconda llama-index in your shell or terminal.
Like so:
conda install -c anaconda llama-index
This assumes you’ve already installed conda on your computer. If you haven’t check out the installation steps on the official page.
How to Install Llama Index in VSCode?
You can install Llama Index in VSCode by using the same command pip install llama-index in your Visual Studio Code shell or terminal.
pip install llama-index
If this doesn’t work — it may raise a No module named 'llama_index' error — chances are that you’ve installed it for the wrong Python version on your system.
To check which version your VS Code environment uses, run these two commands in your Python program to check the version that executes it:
import sys print(sys.executable)
The output will be the path to the Python installation that runs the code in VS Code.
Now, you can use this path to install Llama Index particularly for that Python version:
/path/to/vscode/python -m pip install llama-index
Wait until the installation is complete and run your code using llama-index again. It should work now!
