AWS linux : ansible 2.9.7 using ec2.py and python 3.7 getting : ImportError: No module named boto , boto do installed

i installed python 3.7 

 python --version
Python 3.7.6

i have python 2.7 installed also but i dont want to use it
so i set :
set alias python=python3

ansible : 

ansible --version
ansible 2.9.7
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/ec2-user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/ec2-user/.local/lib/python3.7/site-packages/ansible
  executable location = /home/ec2-user/.local/bin/ansible
  python version = 3.7.6 (default, Feb 26 2020, 20:54:15) [GCC 7.3.1 20180712 (Red Hat 7.3.1-6)]

in /etc/ansible/hosts i set the ec2.py from here :
https://raw.githubusercontent.com/ansible/ansible/stable-2.9/contrib/inventory/ec2.py
but when i run : 

ansible localhost -m ping

I'm getting :

[WARNING]:  * Failed to parse /etc/ansible/hosts with script plugin: Inventory script (/etc/ansible/hosts) had an execution error: Traceback (most recent call last):   File "/etc/ansible/hosts", line 164, in <module>     import boto

Let's start from where you began (versions will be a bit different on my system but result will be the same).

You have python 2.7 installed

$ which python
/usr/bin/python
$ python --version
Python 2.7.17

Your inventory script is executable with the shebang: #!/usr/bin/env python. This gives at the moment:

$ /usr/bin/env python --version
Python 2.7.17

Now, you also have python3 installed

$ which python3
/usr/bin/python3
$ python3 --version
Python 3.6.9

Since you prefer using python3, you create an alias so that the python command line points to your preferred version

$ alias python=python3
$ python --version
Python 3.6.9

You now think that any call to python will direct to python3... except this is absolutely not true when using env

$ /usr/bin/env python --version
Python 2.7.17

Conclusion: you need to change your inventory script sheebang line to one of the following:

#!/usr/bin/env python3
#!/usr/bin/python3

It looks like an installation issue.

  configured module search path = ['/home/ec2-user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/ec2-user/.local/lib/python3.7/site-packages/ansible
  executable location = /home/ec2-user/.local/bin/ansible

Ansible python module is /home/ec2-user/.local/lib/python3.7 which is in .local

try which python3 use that path for running the command ansible localhost -m ping -e 'ansible_python_interpreter=<path goes here>
