How to debug why it is not working on MacOS?

[cipri-tom]

Hi there,

I have conda, mamba and completion for both installed in the base environment, on MacOS, but with bash ! At the same time, I have bash-completion2 installed with homebrew.

For some reason, conda doesn't complete. However, mamba completes, but only once, with repoquery. Second <tab> in mamba <tab>repoquery<tab> gives an error: -bash: _comp_conda: command not found .

So it seems that the installation did not work. How can I debug this ?

In my .bashrc, I have this: [[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"

And in my .bash_profile the block that conda initialization puts, but nothing about completion.

Maybe I need to put the conda file somewhere, instead of direct installation ? But I'm not sure where. Any pointers?

Thank you very much for the package, and for the maintainance !

Hi @cipri-tom. :wave:

First question: which installation method did you use?

Second question: do you have your base environment active by default?

My first guess is that you have the mamba completion script installed and active, but not the conda one.

Hi @tartansandal !

I used method 1: mamba install mamba-bash-completion, which installs 3 packages: bash-completion, conda-bash-completion, and mamba-bash-completion.

(base) $ conda list | grep compl
bash-completion           2.11                 h694c41f_1    conda-forge
conda-bash-completion     1.7                  h694c41f_1    conda-forge
mamba-bash-completion     1.0                  h694c41f_1    conda-forge

Yes, the base is active by default.

I suspect the completion is installed in a folder that bash doesn't look into. I don't know which one, nor how to tell the completion part to look there (I suppose it's not source )

Thank you for your help in this !

Apologies for the late reply -- I've been sick with COVID and complications for the passed 4 weeks.

Since you already had bash_completion2 installed via homebrew, using the (manual) method2 should work. And to keep things clean do mamba remove mamba-bash-completion. I'm not sure what will happen if both methods are used at the same time.

Note, manual installation method2 puts the files under ~/.local/share/... whereas the automatic installation method puts the files under your conda/mamba base environment and used special tweaks to the included bash_completion library to get them to be called.

Hey, no worries ! Thank you for taking effort through the sickness to look at this ! Hope you recover well and fully !!

Great, I've installed manually. I've put the conda from this repo, and mamba from the mamba completion into /usr/local/Cellar/bash-completion@2/2.13.0/share/bash-completion/completions because I wasn't sure if ~/.local/share/... would be taken into account.

And yes, conda works now.

mamba completes, but with weird stuff:

$ mamba ac<tab>
aclocal       aclocal-1.10  aclocal-1.11  aclocal-1.12  aclocal-1.13  aclocal-1.14  aclocal-1.15  aclocal-1.16  acpi

Ah, it's because I was in the completions directory, so it was completing with names from there. If I move to home folder, mamba doesn't suggest any completions. Should I open an issue in mamba completion repo ?

Here's the trace from set -x, if it helps:

[tartansandal]

The last line of the logs:

• compopt -o bashdefault -o default

indicates that it is falling back to default completion. Maybe you need to restart your terminal to get a fresh shell after moving the files around? :thinking: Note: the lasy-loading of the completion scripts may have become confused.

🤦 that was it, indeed ! Sorry I made you read through all that for such a simple fix .

Thanks immensely for your help !

Wishing you great health !
