Another active Homebrew process is already in progress

Question

When I try to do this:

brew install node

I get this message:

 /usr/local/Homebrew/Library/Homebrew/utils/lock.sh: line 19:         


        

Answer 1

I don't know what was going on. My only active terminal was waiting for input, no jobs running in the background. I had just tried to run an RVM install that failed and asked me to update Homebrew but that was supposed to be finished since the terminal was waiting for input. After several repeat command invocations and a couple of minutes later I stopped receiving the message.

This is on Mac OSX 10.13.6 with iTerm2.
