Hi,

Since last week we see our Azure DevOps pipeline failing on the "install outsystems-pipeline package" step.

Hi @stevendecock, which Python version are you attempting to use to run pip? Unfortunately, some of our code's dependencies are not yet available for the most recent Python version.

I would suggest using an older version of Python, such as 3.7.

Hi @duarte-castano,

Indeed, that helped. If anyone else is struggling with this, I added this task in the beginning of my pipeline to set the python version to 3.7:

# Use Python version
# Use the specified version of Python from the tool cache, optionally adding it to the PATH
- task: UsePythonVersion@0
  inputs:
    versionSpec: '3.7' 
    addToPath: true 
    #architecture: 'x64' # Options: x86, x64 (this argument applies only on Windows agents)
