FileNotFoundError: [Errno 2] No such file or directory: 'node'

I think the problem is related to missing node in the configured path for this functionality.

To Reproduce

1. edit a website theme
2. click save
3. error is thrown

Expected behavior
Save the website theme.

After digging in the error, I found that frappe is looking for node in this locations:
executable_list = (b'/opt/user/.bin/node', b'/usr/local/sbin/node', b'/usr/local/bin/node', b'/usr/sbin/node', b'/usr/bin/node', b'/sbin/node', b'/bin/node')

But the frappe-manager container does not have node in any of those paths.

Executing which node inside the bench (fm shell _benchname_ ) shows /workspace/.nvm/versions/node/v22.18.0/bin/node

As a workaround I created a symlink, inside the bench:
ln -s /workspace/.nvm/versions/node/v22.18.0/bin/node /opt/user/.bin/node

Now, saving a Website theme is working as expected 🎉

Any comments on a better solution ?

Currently the node in the container is managed by nvm. I think nvm is not loading in this case.
Check if NVM is again loading in .zshrc or .bashrc,if exits then remove it. Need to check why this might be happening ?
Have you migrated from v17 or this is new site in v18 ?

Hello @Xieyt

Yes, I migrated from v17

Here is the content of .zshrc inside the container (fm shell benchname) :
