Installation Dependency issues.

[littletuna4]

Hi all, I've spent all afternoon trying to install the wiki app and now my instance has style issues for the wiki pages as pictured below. In addition to being visually broken, the wiki cannot be edited from the website side.

I was met with an integrity error due to redis versions (specifically, no module named redis.commands & issues with bleach versions) that I have attempted to resolve as per Goeffrey Karani's video along with a pip install -U redis bleach --force)

Finally, with the non-atomic app uninstallation handled, this is the installation statement I have used: docker exec -it <backend container id> bench get-app wiki --branch version-14 --resolve-deps --overwrite; docker exec -it <backend container id> bench install-app wiki;

Instance details:

• Docker installation on Ubuntu 22.04
• Image: frappe/erpnext:v14.27.1
• frappe 14.38.0
• wiki 2.0.0 (from the version-14 branch because master was also giving errors)
• One 'site' on server "frontend" as per default docker installation of frappe/erpnext

Wiki app is installed on the frontend site.

Can anyone suggest a fix? Does the wiki app have to be on a different hostname to the website maybe?

Thanks in advance for any help.

Hi, the errors are from mismatched dependencies with what you have in your system and what frappe requires. I'm not sure about why the styles are messed up. Can you try reinstalling wiki again?

Thanks for the prompt reply @BreadGenie, being containerized, the dependencies can be managed independently to the system no?

I can only seem to avoid this error: no module named 'redis.commands' from File "apps/wiki/wiki/wiki/doctype/wiki_page/search.py", line 9, in <module> from redis.commands.search.field import TextField

by forcing this condition in the container: frappe 14.38.0 requires bleach~=3.3.0, but you have bleach 6.0.0 which is incompatible. frappe 14.38.0 requires redis~=3.5.3, but you have redis 5.0.1 which is incompatible.

Reinstallation of the wiki app has not changed anything - I'm considering a fresh frappe install.

Yes, That's what I meant but came out wrong 😅

frappe 14.38.0 requires bleach~=3.3.0, but you have bleach 6.0.0 which is incompatible. frappe 14.38.0 requires redis~=3.5.3, but you have redis 5.0.1 which is incompatible.

As long as you can install these packages following these versions the errors should go away.

The dependency issue and the style issue aren't related btw. The latter seems to be originating from something else.

Ok thanks, do you have any insight as to why the version-14 branch seems to work, while the master branch does not? When I try to use the master branch, I get the following error (for all wiki-related doctypes): ImportError: Module import failed for Wiki Page, the DocType you're trying to open might be deleted. Error: cannot import name 'RedisClusterException' from 'redis.exceptions' (env/lib/python3.10/site-packages/redis/exceptions.py)

Once again, appreciate your help.

Frappe Framework recently bumped the dependency versions of redis to 4.5.5 and bleach to 6.0.0 in develop branch but this isn't the case for version-14 of Frappe Framework. Reference: https://github.com/frappe/frappe/blob/develop/pyproject.toml

So inorder to be compatible with respective branches we are maintaining version-14 (compatible with only version-14) and master (compatible with develop and version-15-beta ).

Additionally, this comes up in the error logs, I'm not sure exactly what the wiki module that's missing would refer to:

Ok, I have resolved the dependency issue that resulted in the broken functionality (although this has not resolved the styles).

I'm not exactly sure why, but a docker exec -it <backend container id> bench pip uninstall wiki seemed to work.

This is the full statement I used each time while fiddling with the dependencies. docker exec -it <Backend Docker Container Id> bench uninstall-app wiki; docker exec -it <Backend Docker Container Id> bench remove-app wiki; echo 'DELETE FROM `tabModule Def` WHERE name="wiki"' | docker exec -i <Backend Docker Container Id> bench mariadb; docker exec -it <Backend Docker Container Id> bench get-app wiki --resolve-deps --overwrite; docker exec -it <Backend Docker Container Id> bench install-app wiki;
