CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team

I'm trying to run docker-compose (which was installed via pip), yet running into following error:

Is there a way to force docker-compose to use python3 instead of python (python2)?

Ansible - pip3 install fails

6

I am trying to install Ansible on CentOS 7, and have Ansible configured to use Python 3. I've both Python2 and Python3 installed.

[root@ansible1 ~]# python --version
Python 2.7.5
[root@ansible1 ~]# python3 --version
Python 3.6.8

If I install Ansible using yum install ansible, the ansible --version command shows that Ansible is configured to use Python 2.7.5. I uninstall ansible (yum remove ansible);

[root@ansible1 ~]# ansible --version
ansible 2.9.10
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

According to https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html:

The easiest way to run /usr/bin/ansible under Python 3 is to install it with the Python3 version of pip. This will make the default /usr/bin/ansible run with Python3

I have version 9.0.3 of pip installed.

[root@ansible1 ~]# pip3 --version
pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

Following Ansibles documentation, I issue pip3 install ansible to install Ansible using pip3.

[root@ansible1 ~]# pip3 install ansible

Here is the output of the pip3 show ansible command.

However, the ansible --version command returns the following.

-bash: /bin/ansible: No such file or directory

Likewise, /usr/bin/ansible --version:

-bash: /usr/bin/ansible: No such file or directory

The pip show ansible command shows that the location is /usr/local/lib/python3.6/site-packages/ansible. This directory exists, and contains many files and folders, but no Ansible specific configuration files (e.g. ansible.cfg) or binary files (e.g. ansible) that can be used (best I can tell).

'pip install carbon' looks like it works, but pip disagrees afterward

7

I'm trying to use pip to install the package carbon, a package related to statistics collection. When I run pip install carbon, it looks like everything works. However, pip is unconvinced that the package is actually installed. (This ultimately causes trouble because I'm using Puppet, and have a rule to install carbon using pip, and when puppet asks pip "is this package installed?" it says "no" and it reinstalls it again.)

How do I figure out what's preventing pip from recognizing the success of this installation?

Here is the output of the regular install:

How do I list the files associated with a Python package installed using pip or easy_install?

I've installed a Python package using pip, which is a replacement for easy_install. How do I get a list of which installed files are associated with this package?

Basically, I'm looking for the Python package equivalent of
