Conflicts with r-lib/actions/setup-r on macOS #375
Description
Describe the bug
In this workflow, we use both r-lib/actions/setup-r and setup-graphviz.
Recently the workflow began to error on macOS only; the key lines are:
==> Upgrading 1 dependent of upgraded formulae:
Disable this behaviour by setting HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/R
Target /usr/local/bin/R
already exists. You may want to remove it:
rm '/usr/local/bin/R'
To force the link and overwrite all conflicting files:
brew link --overwrite r
To list all files that would be deleted:
brew link --overwrite --dry-run r
Possible conflicting files are:
/usr/local/bin/R -> /Library/Frameworks/R.framework/Resources/bin/R
/usr/local/bin/Rscript -> /Library/Frameworks/R.framework/Resources/bin/Rscript
To Reproduce
Steps to reproduce the behavior:
# In an action
jobs:
job-name:
steps:
- uses: r-lib/actions/setup-r@v2
- uses: ts-graphviz/setup-graphviz@v1.1Expected behavior
Both are installed and usable on the job runner.
I was able to work around the error by reversing the order: setup-graphviz before setup-r. Usability would be better if the actions were not sensitive to order.
