Check Existing Issues

• I have searched for any existing and/or related issues.
• I have searched for any existing and/or related discussions.
• I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
• I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

v0.6.43

Ollama Version (if applicable)

No response

Operating System

macOS Seqouia

Browser (if applicable)

No response

Confirmation

• I have read and followed all instructions in README.md.
• I am using the latest version of both Open WebUI and Ollama.
• I have included the browser console logs.
• I have included the Docker container logs.
• I have provided every relevant configuration, setting, and environment variable used in my setup.
• I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
• I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
• Start with the initial platform/version/OS and dependencies used,
• Specify exact install/launch/configure commands,
• List URLs visited, user input (incl. example values/emails/passwords if needed),
• Describe all options and toggles enabled or changed,
• Include any files or environmental changes,
• Identify the expected and actual result at each stage,
• Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

When loading a filter function with a requirements frontmatter (e.g., requirements: httpx>=0.24.0), the system should check if the package is already installed in the current environment. If the package exists and satisfies the version requirement, it should skip the installation process

Actual Behavior

The system unconditionally attempts to run pip install via subprocess for every requirement listed in the frontmatter, regardless of whether it is already installed.

In environments managed by tools like uv or nix, shelling out to pip often fails (returning exit code 1) because the environment is locked or pip is not available in the expected path. This causes the backend to crash with a subprocess.CalledProcessError, even if the required package (e.g., httpx) is already present in site-packages.

Steps to Reproduce

1. Setup a clean environment using uv on Python 3.11:

uv venv venv --python 3.11
source .venv/bin/activate

3. Install httpx

uv pip install https==0.26

2. Launch the server:

DATA_DIR=./data open-webui serve

3. Import or load a Filter/Tool that has requirements in the frontmatter (e.g., requirements: httpx>=0.24.0), via Admin Panel → Functions → + (Add Function) → {Paste Code} i.e.

```python
"""
title: Placeholder Filter
author: fractuscontext
version: 0.1.0
requirements: httpx>=0.24.0 # HERE!!
"""

from typing import Optional
from pydantic import BaseModel, Field
import logging

# code omitted (imports)

log = logging.getLogger(__name__)

class Filter:
    class Valves(BaseModel):
        priority: int = Field(default=0, description="Priority level.")
        # code omitted (other valves)

    def __init__(self):
        self.valves = self.Valves()
        # code omitted (initialization logic)

    async def inlet(
        self,
        body: dict,
        __user__: Optional[dict] = None,
        __metadata__: Optional[dict] = None,
        __request__: Optional[object] = None,
    ) -> dict:
        
        log.info("Filter inlet triggered")
        
        # code omitted (timestamp fetching)
        # code omitted (filtering logic)
        
        return body

    async def outlet(
        self,
        body: dict,
        __user__: Optional[dict] = None,
        __metadata__: Optional[dict] = None,
        __request__: Optional[object] = None,
    ) -> dict:
        
        # code omitted (outlet logic)
        
        return body

4. Error!

subprocess.CalledProcessError: Command '['/Users/haruka/Desktop/openwebui/.venv/bin/python3', '-m', 'pip', 'install', 'httpx>=0.24.0']' returned non-zero exit status 1.

Additional Information

It seems to caused by install_frontmatter_requirements in open_webui/utils/plugin.py (or similar loader logic) calling subprocess.check_call without verifying importlib.metadata first.

Originally created by @fractuscontext on GitHub (Jan 2, 2026). Original GitHub issue: https://github.com/open-webui/open-webui/issues/20320 ### Check Existing Issues - [x] I have searched for any existing and/or related issues. - [x] I have searched for any existing and/or related discussions. - [x] I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!). - [x] I am using the latest version of Open WebUI. ### Installation Method Pip Install ### Open WebUI Version v0.6.43 ### Ollama Version (if applicable) _No response_ ### Operating System macOS Seqouia ### Browser (if applicable) _No response_ ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have **provided every relevant configuration, setting, and environment variable used in my setup.** - [x] I have clearly **listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup** (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc). - [x] I have documented **step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation**. My steps: - Start with the initial platform/version/OS and dependencies used, - Specify exact install/launch/configure commands, - List URLs visited, user input (incl. example values/emails/passwords if needed), - Describe all options and toggles enabled or changed, - Include any files or environmental changes, - Identify the expected and actual result at each stage, - Ensure any reasonably skilled user can follow and hit the same issue. ### Expected Behavior When loading a filter function with a `requirements` frontmatter (e.g., `requirements: httpx>=0.24.0`), the system should check if the package is already installed in the current environment. If the package exists and satisfies the version requirement, it should skip the installation process ### Actual Behavior The system unconditionally attempts to run `pip install` via `subprocess` for every requirement listed in the frontmatter, regardless of whether it is already installed. In environments managed by tools like `uv` or `nix`, shelling out to `pip` often fails (returning exit code 1) because the environment is locked or `pip` is not available in the expected path. This causes the backend to crash with a `subprocess.CalledProcessError`, even if the required package (e.g., `httpx`) is already present in site-packages. ### Steps to Reproduce 1. Setup a clean environment using uv on Python 3.11: ```bash uv venv venv --python 3.11 source .venv/bin/activate ``` 3. Install `httpx` ```bash uv pip install https==0.26 ``` 2. Launch the server: ```bash DATA_DIR=./data open-webui serve ``` 3. Import or load a Filter/Tool that has requirements in the frontmatter (e.g., `requirements: httpx>=0.24.0`), via `Admin Panel → Functions → + (Add Function) → {Paste Code}` i.e. ``` ```python """ title: Placeholder Filter author: fractuscontext version: 0.1.0 requirements: httpx>=0.24.0 # HERE!! """ from typing import Optional from pydantic import BaseModel, Field import logging # code omitted (imports) log = logging.getLogger(__name__) class Filter: class Valves(BaseModel): priority: int = Field(default=0, description="Priority level.") # code omitted (other valves) def __init__(self): self.valves = self.Valves() # code omitted (initialization logic) async def inlet( self, body: dict, __user__: Optional[dict] = None, __metadata__: Optional[dict] = None, __request__: Optional[object] = None, ) -> dict: log.info("Filter inlet triggered") # code omitted (timestamp fetching) # code omitted (filtering logic) return body async def outlet( self, body: dict, __user__: Optional[dict] = None, __metadata__: Optional[dict] = None, __request__: Optional[object] = None, ) -> dict: # code omitted (outlet logic) return body ``` 4. Error! ``` subprocess.CalledProcessError: Command '['/Users/haruka/Desktop/openwebui/.venv/bin/python3', '-m', 'pip', 'install', 'httpx>=0.24.0']' returned non-zero exit status 1. ``` ### Logs & Screenshots ``` 2026-01-02 15:11:35.743 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50505 - "GET /api/models HTTP/1.1" 200 2026-01-02 15:11:35.767 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50507 - "GET /api/changelog HTTP/1.1" 200 2026-01-02 15:11:35.789 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50507 - "GET /api/v1/functions/ HTTP/1.1" 200 2026-01-02 15:11:35.814 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50507 - "GET /api/v1/functions/list HTTP/1.1" 200 2026-01-02 15:11:36.146 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50505 - "GET /api/version/updates HTTP/1.1" 200 2026-01-02 15:11:56.850 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50521 - "POST /api/v1/functions/load/url HTTP/1.1" 200 2026-01-02 15:12:00.197 | INFO | uvicorn.protocols.http.httptools_impl:send:476 - 127.0.0.1:50521 - "POST /api/v1/utils/code/format HTTP/1.1" 200 2026-01-02 15:12:00.239 | INFO | open_webui.utils.plugin:install_frontmatter_requirements:270 - Installing requirements: httpx>=0.24.0 /Users/haruka/Desktop/open-webui-fix-deps/backend/venv/bin/python3: No module named pip 2026-01-02 15:12:00.334 | ERROR | open_webui.utils.plugin:install_frontmatter_requirements:278 - Error installing packages: httpx>=0.24.0 2026-01-02 15:12:00.334 | ERROR | open_webui.routers.functions:create_new_function:222 - Failed to create a new function: Command '['/Users/haruka/Desktop/open-webui-fix-deps/backend/venv/bin/python3', '-m', 'pip', 'install', 'httpx>=0.24.0']' returned non-zero exit status 1.
