RequestsDependencyWarning: urllib3

October 26, 2020

One day I was running an Ansible Ad-hoc command on my system for testing purposes, suddenly a python related error popped up from nowhere. At first, I thought it gonna chase me till the laptop battery gets drained out of juice.

The error I get in the command prompt is documented below.

$ ansible web -m command -a "w"
/usr/lib/python3.6/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.11) or chardet (3.0.4) doesn't match a supported version!
RequestsDependencyWarning)

At first, I got totally confused about how did this error came into my system, then I got some idea about past sessions with my systems, I did try to install the following packages. I got these commands from history.

318 sudo apt install python
319 sudo apt install python-pip
320 pip install boto boto3 ansible
321 sudo yum install python
322 sudo yum install python36
323 sudo yum install python-pip

someone from these 6 operations caused the error, so I just tried the same old story, Googled the error.

And the first GitHub post comes to the rescue, I got a result for the exact fix for the issue.

The fix was simple but it was effective, the command and its output is mentioned below.

$ pip install --upgrade requests

Once after the command run successfully, I give a try for the same Ansible - Ad hoc Command and this time everything worked well without any errors.

$ ansible web -m ping
node1 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
node2 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

I recommend reviewing the Github post for a better understanding cause for the error.

THE END (^_^)
