Cannot install container wrapper for bids apps: qsiprep, fmriprep etc

I have tried several times to install the container wrapper for e.g. qsiprep. It seems that the pip installation works, but I then can’t use qsiprep-docker.

pip3 install --user --upgrade qsiprep-container
Requirement already up-to-date: qsiprep-container in /home/quintin_frerichs/.local/lib/python3.8/site-packages (0.12.2)

I get this error:
qsiprep-docker /home/quintin_frerichs/data/ds001590-download
/home/quintin_frerichs/data/qsiprep-output participant --participant_label sub-01
bash: qsiprep-docker: command not found

Docker is also installed (docker --version
Docker version 19.03.15, build 99e3ed8919)

I’ve resolved the issue.

add the path of these wraper

Sorry, now I still stuck in this issue.
How to add the path of these wraper?

My error:
pip install --user --upgrade qsiprep-container
Requirement already up-to-date: qsiprep-container in ./.local/lib/python3.8/site-packages (0.13.0)
qsiprep-docker
qsiprep-docker: command not found

Thanks,
