Source Code Compilation and Build

Obtain the langchain-core source code, build a wheel from the source code, and install the local build product. Build sequence: langchain-core, langchain-text-splitters, and LangChain.

1. Obtain the LangChain source code.

   1	git clone https://github.com/langchain-ai/langchain.git

2. Build the langchain-core wheel from the source code.

   1 2	cd langchain/libs/core python3 -m build --wheel --outdir dist

   The following is an example of the build product.

   1	langchain_core-1.4.3-py3-none-any.whl

3. Build the langchain-text-splitters wheel from the source code.

   1 2	cd ../text-splitters python3 -m build --wheel --outdir dist

   The following is an example of the build product.

   1	langchain_text_splitters-1.1.2-py3-none-any.whl

4. Build the langchain wheel from the source code.

   1 2	cd ../langchain python3 -m build --wheel --outdir dist

   The following is an example of the build product.

   1	langchain_classic-1.0.7-py3-none-any.whl

5. Return to langchain/libs to install the local build product.
