Problem with the initial configuration in production enviroment

[lauraffusal]

Hello everyone, I am new in this and I am interesting in having an installation of this software. First of all I am trying to make I local instalation. I am following these steps https://github.com/sleede/fab-manager/blob/master/doc/production_readme.md

During the installation everything semes to be ok, but try to access to my local instalation I get this erro message:

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

In app-stdout.log I get this message:

Completed 500 Internal Server Error in 18ms (ActiveRecord: 4.4ms | Elasticsearch: 0.0ms)
  
ActionView::Template::Error (Webpacker can't find application.css in /usr/src/app/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
}
):
    54:       Fablab.sessionTours = [];
    55:   </script>
    56: 
    57:   <%= stylesheet_packs_with_chunks_tag 'application', media: 'all' %>
    58:   <%= stylesheet_packs_with_chunks_tag 'plugins', media: 'all' %>
    59:   <%= stylesheet_packs_with_chunks_tag 'printer', media: 'print' %>
    60:   <% unless Stylesheet.theme.nil? %>

I can't find any manifest.json or webpacker.yml. How can I solve that problem?

Hi,
There may be an error with the assets compilcation.
You can try to build them again, running the following:

docker-compose run --rm fabmanager bundle exec rails assets:precompile

Hello, thank you for your response. Now I am trying to install the software in another server. In this server I get a problem too. When I run this command I get:

If I run the command:
docker-compose down && docker-compose up

I get the following message in loop. In the log files I have the same information.

Could you help me? Thank you in advanced!

Hi ! I've the same problem with the original production installation on Ubuntu Server 18.04 :

/usr/local/bundle/gems/ffi-1.12.2/lib/ffi/library.rb:112: [BUG] Illegal instruction at 0x00007f4a184bf904
ruby 2.6.6p146 (2020-03-31 revision 67876) [x86_64-linux-musl]
...

Seems to be a Ruby bug (?)

Working on a fix by rebuilding the sleede/fab-manager docker image with another version of the 2.6.6-alpine image version of Ruby (replacing 2.6.6-alpine by 2.6.7-alpine)

UPDATE : Seems to work, I've successfully installed Fab-manager with the modified image (with some errors and I've also had to edit the initial install script) but it works !

If you want @Sylvain, we can share about this solution (I also speak French btw)

Hi @binForYou,
I updated ffi in v4.7.0 guessing that fixes the issue but if you experienced the issue with a later version, I'll be pleased to integrate your fix in Fab-manager.

You can do it by forking the project then opening a pull request on GitHub.
Thanks,

[TooT]

Hello @binForYou it seems I'm running into the same issue you have been. Except that Ruby 2.6.7 is already in place, but I have the same instruction error during the installation script :
/usr/local/bundle/gems/ffi-1.15.1/lib/ffi/library.rb:112: [BUG] Illegal instruction at 0x00007f68eb1f4904ruby 2.6.7p197 (2021-04-05 revision 67941) [x86_64-linux-musl]

I'm on a brain new fresh install and stay stuck on this issue...

[Sylvain]

According to this thead, the issue may be related to some CPU architecture details, especially when using VM. There's a chance that a further version of sassc fixes the issues. I'll try to update it in the upcoming version and keep you updated.

[Sylvain]

@TooT @binForYou The issue has been addressed in Fab-manager v5.1.10. You can proceed with the upgrade to solve it.

[TooT]

Thanks a lot @Sylvain ! I keep you updated about this issue.
