Hey there 👋

If you’re getting that error, it’s likely the pgvector package isn’t available for your OS or PostgreSQL version via the package manager.

You can always build it from source:

git clone https://github.com/pgvector/pgvector.git
cd pgvector
make
sudo make install

Then in psql:

CREATE EXTENSION vector;

What OS are you running?

You’ll need to built it from source I think

git clone https://github.com/pgvector/pgvector.git
cd pgvector
make
sudo make install

If everything compiles without errors, this installs pgvector to your PostgreSQL extensions directory.

Now connect to your database using psql and run

CREATE EXTENSION vector;

that will enable thje extension for you.
