Do I have to install requirements.txt by myself after galaxy install?

[ggicci]

SUMMARY

After installing by using galaxy CLI: ansible-galaxy collection install amazon.aws. I got error as below when I ran ansible-inventory --graph:

ERROR! The ec2 dynamic inventory plugin requires boto3 and botocore.

I saw the required packages hadn't been installed in my .venv. So do I have to install the required packages by myself? Like calling pip install -r collections/ansible_collections/amazon/aws/requirements.txt?

OS / ENVIRONMENT

Ubuntu 18.04.5

STEPS TO REPRODUCE

mkdir -p /tmp/ansible-venv && cd $_
source bin/activate
pip install "ansible==2.10.0"
ansible --version # print 2.10.1 (confused here, I thought I installed 2.10.0)
ansible-galaxy collection install amazon.aws
ansible-inventory --graph

Since I have xxx.aws_ec2.yml under my inventories folder, the last command ansible-inventory --graph will fail.

EXPECTED RESULTS

The command ansible-inventory --graph should work.

@ggicci ansible-galaxy command only installs collection and not the required libraries. You will need to install the required libraries using the pip command.

I see. Thanks for the reply. BTW, could you explain why not automatically installing the dependencies required by the collections? Will it bring any side effects?

And further more, do we have an option to install them when installing the collections? e.g. ansible-galaxy collection install xxx --with-dependencies. It will be great helpful, IMO.

[Akasurde]

Basically, dependencies are maintained by the third party. Installing them using ansible-galaxy command makes the user think that they are supported and maintained by collection/Ansible as well (which is not true).

Ansible never installs dependencies for the user, since every user's environment might differ.

You might want to take a look at this issue ansible/ansible#69174 for further information.
