## Introduction

Remove a custom library from a project.

```
$ lean library remove [OPTIONS] PROJECT NAME
```

To use the CLI, you must be a member in an [organization](https://www.quantconnect.com/docs/v2/cloud-platform/organizations/tier-features.md) on a paid tier.

## Description

Removes a library from a project. This command can remove libraries that are added using `lean library add`, as well as libraries that were manually added to the C# project file or a Python project's `requirements.txt` file.

C# libraries are removed from your C# project file (the file ending in `.csproj`). If `dotnet` is on your `PATH` and `--no-local` is not given, the CLI also restores all dependencies using `dotnet restore`.

Third-party Python libraries are removed from your project's `requirements.txt` file.

Project libraries are removed from your [project configuration file](https://www.quantconnect.com/docs/v2/lean-cli/projects/configuration.md).

The `lean library remove` command expects the following arguments:

| Argument | Description |

| `<name>` | For third-party C# libraries, the name of the NuGet package to remove. For third-party Python libraries, the name of the PyPI package to remove. For project libraries, the path to the library in the `Library` directory of your [organization workspace](https://www.quantconnect.com/docs/v2/lean-cli/initialization/organization-workspaces.md). |
