Cannot start Redmine, searching for gem 'blankslate'
Added by Ivan Cenov 2 months ago
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 *** SIGUSR2 not implemented, signal based restart unavailable! *** SIGUSR1 not implemented, signal based restart unavailable! *** SIGHUP not implemented, signal based logs reopening unavailable! Puma starting in single mode... * Puma version: 6.4.2 (ruby 3.1.3-p185) ("The Eagle of Durango") * Min threads: 0 * Max threads: 5 * Environment: production * PID: 25464 fatal: not a git repository (or any of the parent directories): .git !

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 withpuma -e production -p 3002

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.

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?

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!
Cheers
