While install dependencies using local/install_deps.bash on macOS with go installed, it won't install all dependencies.

On my macOS, I already installed python and go using brew. When I install dependencies using local/install_deps.bash, it always stops after running brew install bazel golang node nodeenv npm pkill python@2 xz command.

Logs like below:

$ local/install_deps_macos.bash

After checking the shell script, I found it starts with #!/bin/bash -ex , which would exit the script when first error occurs. It seems brew would throws error if some component with older version is installed before.

I replace #!/bin/bash -ex with #!/bin/bash -x as workaround, but it seems not perfect.

Hoping this issue could be fix.
