In this troubleshooting article we will solve the problem ‘/bin/sh: 1: /usr/bin/python: not found’ which we have encountered while using the Ansible. The Ansible which is now a days become very popular among DevOps folks. Ansible is a very simple automation tool widely use for managing the infrastructure and continuous delivery. You can install ansible in Linux system and it is agentless.
Recently after installing Ansible 2.2.1 first we encountered with this error that is “module_stdout”: “/bin/sh: 1: /usr/bin/python: not found\r\n”.
sharad@ip-172-31-7-94:~$ ansible -i inventory/staging staging -m ping
172.31.22.117 | FAILED! => {
"changed": false,
"failed": true,
"module_stderr": "Shared connection to 172.31.22.117 closed.\r\n",
"module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n",
"msg": "MODULE FAILURE"
}
Setting of an inventory variable ‘ansible_python_interpreter’ on any host will allow Ansible to auto-replace the interpreter used when executing python modules. Thus, you can point to any python you want on the system if /usr/bin/python on your system does not point to a Python 2.X interpreter.
Solution: To get your ansible working you have to do two things as given below.
1. Install python 2.x in remote server.
### In Ubuntu/Debian system
sudo apt-get update
sudo apt-get install python2.7
2. Set the ‘ansible_python_interpreter’ in inventory file at Ansible Server.
Given below is sample from my inventory file.
[staging:vars]
ansible_python_interpreter=/usr/bin/python2.7
After doing above steps. All gone successfully well. Here is the result.
sharad@ip-172-31-7-94:~$ ansible -i inventory/staging staging -m ping
172.31.22.117 | SUCCESS => {
"changed": false,
"ping": "pong"
}
As the new ubuntu 16 now ships with python3, I had to do this for every host – since ansible uses python 2.7 – fixed my issue 🙂
ansible myhost –sudo -m raw -a “apt-get install -y python2.7 python-simplejson”
Thought I would leave it here as thanks for pointing me in the right direction, in case it helps someone else 🙂
Thank You Djoe!
I have tried putting the code snippet in /etc/ansible/hosts file but it says
”’
ERROR! Attempted to read “/etc/ansible/hosts” as YAML: Syntax Error while loading YAML.
The error appears to have been in ‘/etc/ansible/hosts’: line 46, column 1, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
[servers]
35.167.173.65
^ here
Attempted to read “/etc/ansible/hosts” as ini file: /etc/ansible/hosts:15: Section [staging:vars] not valid for undefined group: staging
”’
The problem is still there, I had overcome it by -e ‘ansible_python_interpreter=/usr/bin/python3’ on CLI
Hi Ashish,
To deal with Syntax issue, setup your vim suitable to work in Ansible. For this you can install the vim plugin.
I will recommend this plugin created by David from honneffer.com https://github.com/pearofducks/ansible-vim .
You should also search for other YAML syntax settings in vim.
I believe you have latest ansible 2.2 version. When you are using this new version you should use ansible_python_interpreter so that it can work with OS which has default python as version 3.x .
As we know Ansible has lots of module which are made on the basis of python 2.x . Python 3 and Python 2 are different so Ansible team is taking time to create more module compatible with Python 3.
I hope you have also gone through with this Ansible url https://docs.ansible.com/ansible/python_3_support.html
Regards
Sharad
