Cannot start Redmine, searching for gem 'blankslate'

Hello,

I upgraded Redmine to 5.1.2 version. Now, Redmine does not start, because of missing file 'blankslate'. here is a part of the log:

E:\data\redmine>puma -p 3002 -e production

I installed gem blankslate (3.1.3), however above error persists.

Interestingly, I have the same version of Redmine installed on another PC and tehere are no this gem blankslate installed and Redmine runs.

I need any hints where to search... what is the problem?

Regards,
Ivan

After research, blankslate is required in path_to\redmine\lib\redmine\views\builders\structure.rb.

However, as I mentioned, I have a Redmine installation non a PC without installed 'blankslate' gem and it works...

yes, I upgrade from 5.0.6 to 5.1.2. I have done upgrade from 0.9.3 till now and follow almost the official procedure. Now I am curious why the same version on two machines behaves differently...

At last I found a solution:
Added in Gemfile

gem 'blankslite'

Then run bundle install. Redmine started with

puma -e production -p 3002

gem 'blankslate'

We have the same problem when we build Redmine from scratch just by raising the version to 5.1.2 in our `Dockerfile`.

Ivan's workaround works like a charm. What we do: to test it

1. Insert `gem 'blankslate'` in Redmine's `Gemfile`
2. Run `bundle install`

I hope there will be a bugfix for this.

This will be fixed in Redmine 5.0.9 and 5.1.3. See #40802.

I just took a glance into the 5.1.3 release road (https://www.redmine.org/versions/195) but the respective ticket #40802 wasn't mentioned. I gather that the fix will not be included in that release, right?

RE: Cannot start Redmine, searching for gem 'blankslate' - Added by Holger Just 19 days ago

An issue can only be assigned to a single version in Redmine. In this case, #40802 is assigned to version 5.0.9.

The respective commit in r22863 was also merged into the 5.1-stable branch in r22864 though and will be included of the 5.1.3 release accordingly.

Oh, that is good news then! Thanks again for your swift reply!
