Problem "bash: _get_comp_words_by_ref: command not found" on docker php:7.4-fpm about symfony-console-autocomplete HOT 4 CLOSED

It looks like bash-completion is not installed. That is the script that has the bash function that you are missing.

In my MacOS .bash_profile, my HomeBrew installed bash-completion added ..

if [ -f $(brew --prefix)/etc/bash_completion ]; then
  . $(brew --prefix)/etc/bash_completion
fi

I suspect you'll need to have something similar in your .bashrc (if that is the right file ... I'm never sure which one should be used).

@rquadling bash_completion is installed in first RUN. I want use it on docker

from symfony-console-autocomplete.

Installing bash_completion only places the necessary code onto the drive. It does not write the necessary command to ~/.bashrc which is why things are failing.

If you shell into your image, and run set | grep 'BASH_COMPLETION[_=]', what do you get?

On my MacOS host, I get ...

BASH_COMPLETION=/usr/local/etc/bash_completion
BASH_COMPLETION_COMPAT_DIR=/usr/local/etc/bash_completion.d
BASH_COMPLETION_DIR=/usr/local/etc/bash_completion.d

These envvars are set by the execution of the /etc/bash_completion on MacOS. I think this command (or something similar for non MacOS) is missing for the shell you are running.

yup, you need another line like

RUN echo "source /etc/profile.d/bash_completion.sh" > ~/.bashrc
