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

Git Clone

Open WebUI Version

v0.9.1

Ollama Version (if applicable)

No response

Operating System

Rocky 9

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

Non-admin users can create tools in a Pyodide environment with properly imported dependency modules.

Actual Behavior

While creating a tool, pyodide raises an exception indicating it cannot find 'click', which is a dependency of black.

Steps to Reproduce

I installed Open WebUI from source.
My environment is offline, so I need to bring it in after vite build.

git clone https://github.com/open-webui/open-webui.git
cd open-webui
npm install
npm run build

send to offline server...

cd backend
pip install -r requirements.txt -U --no-index --find-links {MY_WHEEL_PATH}
sh dev.sh

then make non-admin user and make tool.

Logs & Screenshots

Unfortunately, I'm unable to provide the internal logs due to company security policies. My apologies for the inconvenience.

Additional Information

This issue is likely related to modifying prepare-pyodide.js to allow loading the black library in offline environments (see https://github.com/open-webui/open-webui/issues/22509). The problem occurs when writing libraries fetched from PyPI into the pyodide-lock.json file.

  1. Missing Dependencies in pyodide-lock.json: The black library entry does not include its required dependencies (click, mypy-extensions, packaging, pathspec, platformdirs, pytokens) in the depends field.

  2. Package Name Inconsistency: The package name in pyodide-lock.json uses underscores (mypy_extensions) while micropip expects hyphens (mypy-extensions), causing lookup failures.

I have successfully resolved the issue by modifying the build/pyodide/pyodide-lock.json file as shown below. After this change and adding pytokens(add pypi library list in prepare-pyodide.js), pyodide can now properly load the black library and its dependencies in my enviornment.

script/prepare-pyodide.js needs to be updated to address the above issues when fetching libraries from PyPI during the build process.
