chalk autocomplete feature not working

[indecisivedragon]

Description

On a linux machine, chalk should support autocomplete when tab is pressed, however this does not seem to be working.

Impact

Makes usage more annoying, especially when trying to point chalk towards a local file.

Steps to Reproduce

1. have a working copy of chalk
2. when trying to autocomplete (without any input) the following bash error happens:

liming@system76-pc:~/workspace/chalk$ ./chalk load bash: [: =: unary operator expected
bash: [: =: unary operator expected

3. when trying to autocomplete with input:

liming@system76-pc:~/workspace/chalk$ ./chalk load ./

nothing comes up for the autocomplete.

I get this error:

[root@earth chalk]# source /root/.local/share/bash_completion/completions/chalk.bash
[root@earth chalk]# chalk bash: _get_comp_words_by_ref: command not found

I normally use fish as my shell and therefore dont interact with bash... but looks like things are not working as expected there
