uv pip - check if package installed

To check if a package is installed using uv pip, the command-line interface associated with the UV package manager for Python, you can follow several straightforward steps. Below is a guide that covers the appropriate commands and concepts.

Understanding uv pip

UV is a modern Python package manager designed to provide faster performance and simplified package management compared to traditional tools like pip. With uv pip, users can efficiently manage their Python packages and environments. This tool includes commands for installing, updating, and verifying packages.

Checking Installed Packages with uv pip

To check if a specific package is installed in your Python environment using uv pip, follow these steps:

1. Open Your Terminal

The first step is to open your terminal or command prompt. Make sure that your environment is activated if you're using a virtual environment.

2. Use the uv pip list Command

You can list all installed packages in your current environment by executing the following command:

uv pip list

This command will display a list of all packages currently installed in your environment, along with their versions.

3. Check for a Specific Package

If you want to check for a specific package, you can use the following command. This will provide detailed output if the package is installed:

uv pip show <package-name>

Replace <package-name> with the name of the package you want to verify. For example:

uv pip show requests

This command will display information about the requests package if it’s installed, including its version, location, and dependencies.

4. Use the uv pip check Command

To validate your environment and check for inconsistencies—such as missing dependencies or issues with installed packages—use:

uv pip check

This command will alert you to any problematic packages, ensuring that your environment is healthy and all dependencies are satisfied.
