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?
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

I am trying to use these steps with bitbucket CI to deploy an application:
script:
- apt-get update
- apt-get install -y python-dev
- curl -O https://bootstrap.pypa.io/get-pip.py
- python get-pip.py
... and a few more steps
However, the python get-pip.py step fails with this error:

Why isn't it working now? Does it depend on the operating system?
For the equivalent issue with upgrading pip in old Python installations, see Upgrading pip fails with syntax error caused by sys.stderr.write(f"ERROR: {exc}").
pip 21.0 dropped support for Python 2 and 3.5. The later versions require Python 3.6+. The syntax f"" is supported by Python 3.6+.
To install pip for Python 2.7 install it from https://bootstrap.pypa.io/pip/2.7/ :
- curl -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
- python get-pip.py
- python -m pip install --upgrade "pip < 21.0"
The last command is to upgrade to the latest supported version.
For Python 2.7 the latest supported is currently pip 20.3.4.
For Python 3.6 install from https://bootstrap.pypa.io/pip/3.6/
For Python 3.5 install from https://bootstrap.pypa.io/pip/3.5/
For Python 3.4 install from https://bootstrap.pypa.io/pip/3.4/
For Python 3.4 the upgrade command is
python -m pip install --upgrade "pip < 19.2"
I solved it by firstly run
python -m pip install --upgrade "pip < 19.2"
and then
python -m pip install --upgrade "pip < 21.0".
It seems reinstall my pip 20.3.4 and the error disappreared!
This worked for me:On Mac:
Install pyenv as well as upgrade your python following the instructions on this here
Then in your terminal, if you run python -V and you still get the old version(system predefined version) showing:
To resolve this:
In your terminal run: alias python=python3
Then in your terminal execute python and you should now see that your system is using the python version you installed-:That is if you followed and completed the steps Here Correctly.
Restart your terminal(close/reopen):
Now you can finally install pip:

For me python 3.5 on aws ec2 below worked
curl -O https://bootstrap.pypa.io/pip/3.5/get-pip.py
Then

I have also tried all thing but my solution was download old get-pip version and install.
download: curl -O https://bootstrap.pypa.io/2.7/get-pip.py the file get-pip.py
install: python get-pip.py or python2 get-pip.py
enjoy
This is worked on Debian systems.
Edit: A better solution is always to install a Python version that is long supported. If at all you need to work with an older version - only then must one resort to the above workaround.
Uninstall existing pip on your machine
Run this cmd in ubuntu or any linux machine
curl https://bootstrap.pypa.io/pip/3.5/get-pip.py -o get-pip.py
python3 get-pip.py
It will work

I was just trying to download packages using pip in the terminal in pycharm and there was a notice from pip saying "You are using pip version 10.0.1, however, version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command."
I ran the command but when I typed "pip -V" to check the version, it remained the same 10.0.1. And when I run the command, it says that pip is already up to date
How can solve this?
Your python and pip seem to point to different python versions. Check by typing which python or where python in the terminal.
To make sure they match, you can use
python -m pip install --upgrade pip (as you did) for upgrading
python -m pip install <package name> for installation
I'm trying to test a python project which utilizes the yaml package (pyyaml) using travis-ci.
sudo: required
python: "3.6"
before_install:
- sudo apt-get install -y python3-pip
- sudo pip3 install pyyaml
script:
- ./setup.py test
However travis keeps giving me:
ModuleNotFoundError: No module named 'yaml'
I've tried using plain pip to install pyyaml, as well as the ubuntu package python3-yaml with no luck. I can get it to work on a local VM with ubuntu, just not in travis-ci.
The "ModuleNotFoundError" indicates that it is indeed Python 3.6 that generates the error Python <= 3.5 would give a module error. I would tend to use /path/to/python setup.py test, but it already looks like you have the right Python there.
That leaves that pip3 might not install where you think it installs, so you should at least do:
- sudo /path/to/python36 -m pip install pyyaml
to make sure you get the pip3 that you are expecting, and that you are not using some default system Python 3.5 or earlier.
You could also consider installing virtualenv with a known path, and install pyyaml in there and then run your setup.py with a full path of the python from there.

I installed the tornado package and this happened since. How can I fix it?
This worked for me (running Ubuntu, both 12 and 14 LTS):
pip install -U setuptools
pip install -U pip
Upgrade to the latest version of setuptools in order to be able to upgrade to the latest version of pip, and upgrade to the latest version of pip to get a version that has fixed the AssertException error.
Reason: The python-pip package in Ubuntu 12.04 is seriously outdated and has some bugs with certain package names (as I can see) and cannot parse them correctly.
Solution: install a newer version of pip, via easy_install.
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
hash -r # reset bash cache
https://pip.pypa.io/en/latest/installing.html
I found the solution at this link.
pip install setuptools==7.0
First, I ran Martin Mohan's solution:
/usr/local/bin/pip uninstall pip
apt-get remove python-pip
apt-get install python-pip
Then, boredcoding's ultimately fixed the problem, both solutions are found near bottom of thread: I screwed up the system version of Python Pip on Ubuntu 12.10
$apt-get install python-pip
$which pip
/usr/bin/pip
$pip install -U pip
$which pip
/usr/bin/pip
$hash -r
$which pip
/usr/local/bin/pip
The logic behind these two fix are stated in the thread (linked above), so I will refrain from going into each here.
The problem is due to an old version of pip being installed.
Run the following command to install a new version of pip:
sudo easy_install -U pip.
It may be a bit late, but one thing I found was there are 2 or three versions of pip installed (depending on what you installed)
pip - the OS version installed, freeze doesn't work and it can be out of date
pip2 - the newer one installed but upgrading pip via pip etc
pip3 - installed if you have python3 and python2 installed at the same time.
You can either change which pip gets used in $PATH, or do what I did:
pip2 freeze (which does work on ubuntu14 if you have more than one option for python)
