_get_comp_words_by_ref missing

[diver-sity]

Hi docker-machine authors,
I was trying out the bash completion scripts. After adding
docker-machine.bash
docker-machine-prompt.bash
to ~/.bashrc and "source" them, this error was thrown:

$ docker-machine -bash: _get_comp_words_by_ref: command not found
-bash: ((: i < : syntax error: operand expected (error token is " ")
-bash: _get_comp_words_by_ref: command not found
-bash: ((: i < : syntax error: operand expected (error token is " ")

I searched for _get_comp_words_by_ref in this repository, but only a usage was found. It might have been removed, I guess. Do you guys still have that function by any chance?

_get_comp_words_by_ref is a function provided by the bash-completion package.

Possible causes for your error message would be

• bash-completion is not installed
• bash-completion is not invoked from your login scripts
• you source the completion files before bash-completion is initialized

Thanks @albers . I'm going to close the issue as I think it's related to installation issues

source /etc/profile if you aren't already (i.e.: when using bash with alpine).

source /etc/profile if you aren't already (i.e.: when using bash with alpine).

This worked for bash with centos too.
thanks!
