  Error: /usr/local/Cellar/gazebo11/11.14.0_8 is not a directory

Steps to reproduce

thanks for your report, but there isn't enough information for me to reproduce the problem. I just noticed a different problem with compiling gazebo11 on macOS (#3372). I'll patch the formula with that fix shortly, but after that I'd recommend trying your build again. If it still fails, can you report the failure at the osrf/homebrew-simulation repository and fill out the issue template? That will help us solve the issue together.
