The LangChain ecosystem has many separate packages. You need to know which ones to install and their correct versions. LangChain 1.0 is the current stable release for new projects. Always start there.
This guide covers required packages for Python and TypeScript. It explains environment requirements like Python 3.10+ or Node.js 20+. It also helps you choose between LangGraph and Deep Agents for orchestration. Provider packages like langchain-openai or langchain-anthropic are installed separately.
Version pinning is important. The langchain-community package does not follow semantic versioning. Pin it carefully. This skill helps you avoid incompatibilities and keep upgrades predictable.
