When I try to install ansible role, I see this exception.
$ ansible-galaxy install zzet.postgresql
Traceback (most recent call last):
File "/Users/myHomeDir/.homebrew/Cellar/ansible/1.4.3/libexec/bin/ansible-galaxy", line 34, in <module>
import yaml
ImportError: No module named yaml
OS: Mac Os Maverick
Ansible: 1.4.3
Does anyone know how to fix it?
Based on the error message, it tries to import the python module yaml but cannot find it. The yaml module is called pyyaml when you install it with pip:
pip install pyyaml
If pip is not installed on your mac then you can install it as,
easy_install pip
For me pip install yaml doesn’t work in Mavericks.
pip install pyyaml works
I tried the pip install yaml answer, and it didn't work for me. I had to reinstall ansible in order for the command line to catch. IE,
failing

Try installing with
sudo python -m easy_install pyyaml
The problem isn't in pyyaml, its in your version of setuptools. See http://codyaray.com/2011/12/pyyaml-using-easy_install-on-mac-os-x-lion for references

I'm on Ubuntu 18.04 and using python 2.6.6 that I installed from tgz package from here https://www.python.org/downloads/release/python-266/ using this instruction: https://askubuntu.com/questions/25961/how-do-i-install-a-tar-gz-or-tar-bz2-file. I'm trying to install pip using this instruction https://pip.pypa.io/en/latest/installing/
but when I run
python get-pip.py
I got errors about dependencies:
Traceback (most recent call last): File "get-pip.py", line 28, in

from os import urandom as _urandom ImportError: cannot import name urandom
First it was cannot import name zlib. I installed zlib and now I got about urandom so I guess there might be more that I don't have installed. What's the best way to deal with it?
You could try sudo. If that doesn't work, try stating the python version.
$ sudo python2.6 get-pip.py
I think it is better to install via OS package:
apt install python python-pip python-setuptools
I'm using Python 3.5.2 on Ubuntu 16.04.
I've installed sklearn using..
sudo apt install python-sklearn
and mlxtend using...
sudo pip3 install mlxtend
I'm trying to run the basic Iris example found on the Internet, but I am getting an error as soon as I try to import plot_decision_regions from mlxtend.plotting:

I had the same error, just upgrade to python3.7 the real error is
python 3.5 does not support f prefix
upgrade using conda
conda install -c anaconda python=3.7
and then update all depencies
conda update --all
I'm not seeing the same error as you, but try remove legend=range(105, 150) from plot_decision_regions i.e.
plot_decision_regions(x_combined, y_combined, clf=tree)
I'm using the latest current sklearn, i.e.
import sklearn
sklearn.__version__
'0.21.3'
Perhaps remove that version
sudo apt-get remove python-sklearn
Then install via pip, i.e.
pip3 install scikit-learn
Pip is not installing the module for python correctly
I have upgraded python to 3.7.3 and creted a symbolic link to the new version. I am trying o import the module - requests, but it fails and gives a error. I suspect my links are incorrect.

You should consider upgrading via the 'pip install --upgrade pip' command.

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>

import yaml
ImportError: No module named yaml
What should be done here?
Do you have yaml module installed? If not, try installing yaml using the following command:
sudo pip install pyyaml
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.
For python 3.6 you can install it with
pip3 install pyyaml
if there is a problem in importing, do
pip3 uninstall pyyaml
and then install it again:
pip3 install pyyaml
#bigdata2's answer is correct but it might also happen that there's a conflict with python 3. So, check pip version (pip --version) and if it outputs python 3 then:
sudo python -m pip install pyyaml
So it gets installed for the same version as python.
I had this problem because I installed it with
sudo pip install pyyaml --upgrade
instead of
sudo -H pip install pyyaml --upgrade
Uninstalling and re-installing pyyaml fixed the problem for me.
This should work:
sudo pip install pyyaml
Try this
pip install ruamel.yaml

Can anyone help me troubleshoot???
Thanks,
I think it is because the distribute package is out of date. Certainly the following fixed it for me:
pip install --upgrade distribute
Your pip may be outdated. Even in Ubuntu 14.04 LTS, the pip version it installed using apt-get install python-pip was 1.5.4. Try updating pip manually, and possibly the new packages again as well.
pip --version # 1.5.4
curl -O https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
pip --version # 6.0.8
https://pip.pypa.io/en/latest/installing.html
I know it's old but since I had the same problem and the fix didn't helped. Guess does not harm adding my solution.
Just updated pip, from inside of my virtualenv.
pip install --upgrade pip
