Bug Report

Installation Method

Manual install based on development instructions (and I swear there used to be docs on how to do this, but I can't find them anymore).

Environment

  • Open WebUI Version: v0.5.15

  • Ollama (if applicable): v0.5.11

  • Operating System: Ubuntu 24.04

  • Browser (if applicable): Firefox 135.0

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs. - N/A
  • I have included the Docker container logs. - N/A
  • I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

Install succeeds without error.

Actual Behavior:

npm install fails with error:

(matt@bluebox) ~/storage1/ai/open-webui ((v0.5.15))$ npm install
npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine

npm ERR!     /home/matt/.npm/_logs/2025-02-20T14_51_31_588Z-debug-0.log

Description

Bug Summary:

Following the instructions here: https://docs.openwebui.com/getting-started/advanced-topics/development#-local-development-setup

And synthesizing them into a local production upgrade, e.g.:

npm install
npm run build
source venv/bin/activate
pip install -r backend/requirements.txt -U

(No need to create the venv, it exists already)

The first step fails with the above shown error.

Reproduction Details

Steps to Reproduce:

From soup to nuts:

git clone https://github.com/open-webui/open-webui.git
cd open-webui
git checkout v0.5.14
npm install
npm run build
python3.11 -m venv venv
source venv/bin/activate
pip install --upgrade pip
pip install -r backend/requirements.txt -U
deactivate
# All of the above work for me.
git checkout v0.5.15
npm install  # <--- This step fails. Should succeed.
npm run build
source venv/bin/activate
pip install -r backend/requirements.txt -U

Logs and Screenshots

Log:
2025-02-20T14_51_31_588Z-debug-0.log

Browser Console Logs:
N/A - not happening in browser.

Docker Container Logs:
N/A - Not using docker

Screenshots/Screen Recordings (if applicable):
N/A - see copy paste in "Actual behavior".

Additional Information

I fully realize this may be a PEBTAC problem, because the operator was fed non-updated development instructions. If there is some other command that should be run, docs likely need to be updated.

Oh, and because I expect it will rapidly become relevant:

(matt@bluebox) ~$ node --version

Node 22 is required!

Ah, thank you. So, not a regression. I can't say that I'm surprised by this answer, FWIW.

For anyone finding this, if you're lazy, you can do this to update Node.js on any debianish system:

~$ curl -fsSL https://deb.nodesource.com/setup_22.x | sudo bash - 
~$ sudo apt-get install -y nodejs

If you don't trust random scripts from the internet, do this:

  1. Add key

    wget -O- https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --no-default-keyring --keyring=/usr/share/keyrings/nodesource.gpg --import

  2. Create /etc/apt/sources.list.d/nodesource.list as follows (change arch as necessary):

    deb [arch=amd64 signed-by=/usr/share/keyrings/nodesource.gpg] https://deb.nodesource.com/node_22.x nodistro main

  3. Create /etc/apt/preferences.d/nsolid as follows:

    Package: nsolid
Pin: origin deb.nodesource.com
Pin-Priority: 600

  4. Create /etc/apt/preferences.d/nodejs as follows:

    Package: nodejs
Pin: origin deb.nodesource.com
Pin-Priority: 600

  5. Fix perms:

    sudo chmod a+r /etc/apt/sources.list.d/nodesource.list /etc/apt/preferences.d/nsolid /etc/apt/preferences.d/nodejs

  6. Install it:

    sudo apt update
sudo apt install -y nodejs

Once this is done, v0.5.15 installs and runs using the process described in the bug report.

Thanks to @mattcaron, after reading your very useful comment I managed to get webui built again. Strange thing is the webui server now says it is version v0.5.16, (should have been v0.5.17) plus the client says v0.5.18 is now available - so I can do it all again tomorrow!

I had Node v18. As soon as I read @tjbck 's reply I changed the Node version and it worked.

Here's what you need to do:

# install nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
# list the versions
nvm ls-remote
# install Node v22 (LTS)
nvm install <version>
# make it the default Node
nvm alias default <version>
# confirm
node -v

Then you can run npm install with no problems.
