مرحبًا. أردت تثبيت إضافة (مستكشف البيانات)، لذا أضفت سطر git في ملف app.yml الخاص بي.  
فشل إعادة البناء:

```

ظننت أن المشكلة قد تكون بسبب الإضافة، لذا أزلتها من ملف app.yml الخاص بي وأعدت البناء مرة أخرى، لكن ظهرت نفس الخطأ.  
يعمل موقع Discourse الخاص بي حاليًا، لكنني لا أستطيع إعادة البناء، وقد يتسبب ذلك في مشاكل مستقبلية، لذا أحتاج إلى حل هذه المشكلة.

هل لديك أي فكرة عن كيفية إصلاح ذلك؟

This is a known issue in our new image cc @falco @sam there is an error being reported as part of the rebuild, every time.

I see what this is:

> **[Ruby 2.5 adds Thread.report\_on\_exception by default](https://www.bigbinary.com/blog/ruby-2-5-enables-thread-report_on_exception-by-default)**
>
> Ruby 2.5 series | Ruby 2.5 enables Thread.report\_on\_exception by default and we get more info when threads die

Will sort out pups to allow for this.

Okay so nothing to do on my side, just waiting for an update I guess 🙂

Oh the particular error you are seeing in the logs (which I just fixed) is unrelated.

`bundle exec rake assets:precompile` is failing for you which is usually due to plugins. I would try rebuilding again and triple check there are no plugins involved.

Yes it was because of a plugin. Weird, it didn’t cause this issue before.
