Azure Devops Jekyll site build fails, worked previously

My blog site https://davidjones.sportronics.com.au I submit to Azure Devops where it is built as a Jekyll site. Has worked fine for a several years with only minor updates. Scripts run using Win 2019 VM.

Yesterday the build failed:

Pipeline steps:

• Use Ruby > 3.0.0
• Install Jekyll and Bundler
• Install Gems
• Build
• Copy site to staging directory
• Publish Artifact: _site

Pipeline step: Use Ruby > 3.0.0
Script: Version Spec 3.1.4

Was this (this worked for some time) but failed today. Devops says available versions are 3.0.7 or 3.1.5

Worked on previous submission mid May and for a long time prior.

Tried Version specs as below but fails at Build

• 3.1.5
• 3.0.7
• > 3.0.0 Fir this: Found tool in cache: Ruby 3.1.5 x64

Nb: Local build uses 3.2.2

With these, got past the version check runs next 2 steps OK but build fails:

C:/hostedtoolcache/windows/Ruby/3.1.5/x64/lib/ruby/3.1.0/csv/parser.rb:3:in `require': 126: The specified module could not be found. 

Install Jekyll and bundler: Script:gem install jekyll bundler

I have posted a detailed blog on this: Azure Pipelines: Jekyll Site Build failure

I can reproduce the same issue when using the Microsoft-hosted agent: Windows-2019 in Azure Pipeline.

The cause of the issue could be that the environment settings or the configurations have issues when using the Ruby version 3.1.5 on Windows-2019 agent. You can report the issue to this feedback site: Agent image feedback

To solve this issue, you can refer to the following methods:

Method1: You can change to use the Ruby version: 3.0.7 in Windows-2019 agent.

For example:

- task: UseRubyVersion@0
  inputs:
    versionSpec: '3.0.7'

Method2: You can re-install Ruby version 3.1.5 or other versions in Pipeline with the script. Then the pipeline can run successfully.

Here is an example:

pool:
  vmImage: windows-2019

steps:

- script:  choco install ruby --version=3.1.5.1
- script: |
    gem install jekyll bundler
 
  displayName: Install Jekyll and bundler

- script: 
     bundle install
  displayName: Install Gems
  


- script: 'bundle exec jekyll build'
  displayName: Build

Result:

Method3: You can change to use Microsoft-hosted agent: image Ububtu- 20.04, Ububtu-22.04.

For example:

pool:
  vmImage: ubuntu-latest

Update:

@David Jones has posted the issue report ticket: Using the Ruby version 3.1.5 on Windows-2019 Agent failure. We can keep focus on the feedback from image management team.
