サードパーティ製プラグインがリビルドの失敗を引き起こす

I tried rebuilding my website co it crashed about 4 hours ago… I have no idea how to fix this rebuilding issue. I’ve tried all the fixes on this forum (the ones that I could understand). But none of them worked. Can you guys help me out?
The Error:

> FAILED
Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #<Process::Status: pid 11252 exit 1>
Location of failure: /pups/lib/pups/exec_command.rb:112:in `spawn'

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages,there may be more than one

It asks me to scroll up and check… This is the only error that I could find after scrolling up.

Do you have an non-standard plugins installed?

Only ones from github

Do they all start with https://github.com/discourse?

Yes absolutely! They are all from github.

Virtually every plugin in the world comes from github. They are not all maintained by discourse.org. What plugins do you have?

Remove all plugins and rebuild.

After that, start enabling just the ones you absolutely need, one by one.

Do you see all the plugins that do not start with https://github.com/discourse? You need to comment those out by putting a # at the beginning of the line.

Then rebuild and see that it works.

After that, you can uncomment them one at a time.

But you should probably do what @falco said instead.

Okay got it thanks. I’ll try doing the same.
