Want to share pyenv environment with multiple users on the same machine

I am a beginner in Linux.I am studying using Amazon Linux.

I would like to use Pyenv not only ec2-user but also root, ec2-user2, ec2-user3, etc.
In that case, what kind of composition is appropriate for Linux?
Install as root, install as /usr/local/.pyenv, and
I added root and ec2-user to the development user group, but
The permission of pip coming in with pienv 3.5.2 was 755, so
It seemed to be available only to users who installed it.
Is there any good way to change the executable file such as pip to 775 every time I install a new version in pyenv?

I have another question,
Is it right to manage executable files such as pyenv for each installed user?

Thank you for your cooperation.
