# 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 experimental
|
|
The `langchain-experimental` package holds experimental LangChain code, intended for research and experimental uses.
|
|
Install with:
|
|
|
|
```bash
|
|
pip install langchain-experimental
|
|
```
|
|
|
|
## LangChain CLI
|
|
The LangChain CLI is useful for working with LangChain templates and other LangServe projects.
|
|
Install with:
|
|
|
|
```bash
|

pip install langchain-cli

LangServe helps developers deploy LangChain runnables and chains as a REST API.

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.
