# Installation
|
||||
|
||||
## Official release
|
||||
|
||||
To install LangChain run:
|
||||
|
||||
import Tabs from '@theme/Tabs';
|
||||
import TabItem from '@theme/TabItem';
|
||||
import CodeBlock from "@theme/CodeBlock";
|
||||
|
||||
<Tabs>
|
||||
<TabItem value="pip" label="Pip" default>
|
||||
<CodeBlock language="bash">pip install langchain</CodeBlock>
|
||||
</TabItem>
|
||||
<TabItem value="conda" label="Conda">
|
||||
<CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
This will install the bare minimum requirements of LangChain.
|
||||
A lot of the value of LangChain comes when integrating it with various model providers, datastores, etc.
|
||||
By default, the dependencies needed to do that are NOT installed. You will need to install the dependencies for specific integrations separately.
|
||||
|
||||
## From source
|
||||
|
||||
If you want to install from source, you can do so by cloning the repo and be sure that the directory is `PATH/TO/REPO/langchain/libs/langchain` running:
|
||||
|
||||
```bash
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
## LangChain core
|
||||
The `langchain-core` package contains base abstractions that the rest of the LangChain ecosystem uses, along with the LangChain Expression Language. It is automatically installed by `langchain`, but can also be used separately. Install with:
|
||||
|
||||
```bash
|
||||
pip install langchain-core
|
||||
```
|
||||
|
||||
## LangChain community
|
||||
The `langchain-community` package contains third-party integrations. It is automatically installed by `langchain`, but can also be used separately. Install with:
|
||||
|
||||
```bash
|
||||
pip install langchain-community
|
||||
```
|
||||
|
||||
## LangChain experimental
|
||||
The `langchain-experimental` package holds experimental LangChain code, intended for research and experimental uses.
|
||||
Install with:
|
||||
|
||||
```bash
|
||||
pip install langchain-experimental
|
||||
```
|
||||
|
||||
## LangGraph
|
||||
`langgraph` is a library for building stateful, multi-actor applications with LLMs, built on top of (and intended to be used with) LangChain.
|
||||
Install with:
|
||||
|
||||
```bash
|
||||
pip install langgraph
|
||||
```
|
||||
## LangServe
|
||||
LangServe helps developers deploy LangChain runnables and chains as a REST API.
|
||||
LangServe is automatically installed by LangChain CLI.
|
||||
If not using LangChain CLI, install with:
|
||||
|
||||
```bash
|
||||
pip install "langserve[all]"
|
||||
```
|
||||
for both client and server dependencies. Or `pip install "langserve[client]"` for client code, and `pip install "langserve[server]"` for server code.
|
||||
|
||||
## LangChain CLI
|
||||
The LangChain CLI is useful for working with LangChain templates and other LangServe projects.
|
||||
Install with:
|
||||
|
||||
```bash
|
||||
pip install langchain-cli
|
||||
```
|
||||
|
||||
## LangSmith SDK
|
||||
The LangSmith SDK is automatically installed by LangChain.
|
||||
If not using LangChain, install with:
|
||||
|
||||
```bash
|
||||
pip install langsmith
|
||||
```
