Getting "ImportError: No Module named yaml" error

Question

Computer: MacBook Pro mid 2012, running El Capitan 10.11.4

Python version 2.7.10

I've been trying to install ansible from source, and I've run these two commands (following the steps on ansibles documentation):

git clone git://github.com/ansible/ansible.git --recursive cd ./ansible 

and then ran this

source ./hacking/env-setup 

I've also already installed these packages

sudo pip install paramiko PyYAML Jinja2 httplib2 six 

However, if I try and run ansible by typing it in the terminal, I get the following error.

Traceback (most recent call last): File "/Users/[myusr]/rock/ansible/bin/ansible", line 81, in <module> from ansible.cli.adhoc import AdHocCLI as mycli File "/Users/[myusr]/rock/ansible/lib/ansible/cli/__init__.py", line 27, in <module> import yaml ImportError: No module named yaml 

What should be done here?

Answer 1

Do you have yaml module installed? If not, try installing yaml using the following command:

sudo pip install pyyaml 

Answer 2

Had the same issue. Got past it using @FranMowinckel's answer.

First I typed:

pip --version  

it outputted python 3. But, when I tried:

sudo python -m pip install pyyaml 

I got an error saying:

Error: No module named pip

So, finally running:

sudo easy_install pip 

everything worked fine. Go back and run:

sudo python -m pip install pyyaml 

(you may have to run this with all the other modules as well) Now you should finally be able to run your initial command which failed.
