Strange. Getting package incompatibility error when running on CMS-CI:

 [ErrorException]                                                                                                                                                                        
  Declaration of DevShop\Component\PowerProcess\PowerProcess::mustRun(?callable $callback = NULL) should be compatible with Symfony\Component\Process\Process::mustRun($callback = NULL)  

However composer yaml-tasks works for me locally, on php7.2.

Seeing this error on test run 20 minutes ago, if you could fix:

[error] Conflict merging master into f8b5dcf.

And, unrelated to this PR (it seems) and I will work on fixing this (confused why it is only visible on this PR though):

Step 24 start: Build Webpack assets

Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):

Is because the yarn install at the beginning failed with:

Jon and I debugged this a bit today and I had shared what I debugged a while ago, which was that the post-yarn install commands that were triggering node install.js were actually using the system node (v13) not our application node(v10.5). And it appears there was something going on with the PATH in this refactor of yaml-tasks that changed. Jon removed the global DevShop node and it got past this step successfully now.
