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Reason: The python-pip package in Ubuntu 12.04 is seriously outdated and has some bugs with certain package names (as I can see) and cannot parse them correctly.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Your pip may be outdated.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pip - the OS version installed, freeze doesn't work and it can be out of date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)

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

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.

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'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
CentOS 7 EPEL now includes Python 3.4: yum install python34
However, when I try that, even though Python 3.4 installs successfully, it doesn't appear to install pip. Which is weird, because pip should be included by default with Python 3.4. which pip3 doesn't find anything, nor does which pip.
How do I access pip from the Python 3.4 package in CentOS 7 EPEL release?
The easiest way I've found to install pip3 (for python3.x packages) on CentOS 7 is:
$ sudo yum install python34-setuptools
$ sudo easy_install-3.4 pip
You'll need to have the EPEL repository enabled before hand, of course.
You should now be able to run commands like the following to install packages for python3.x:
$ pip3 install foo
curl https://bootstrap.pypa.io/get-pip.py | python3.4
Or if you don't have curl for some reason:
wget https://bootstrap.pypa.io/get-pip.py
python3.4 get-pip.py
After this you should be able to run
$ pip3
The CentOS 7 yum package for python34 does include the ensurepip module, but for some reason is missing the setuptools and pip files that should be a part of that module. To fix, download the latest wheels from PyPI into the module's _bundled directory (/lib64/python3.4/ensurepip/_bundled/):
setuptools-18.4-py2.py3-none-any.whl
pip-7.1.2-py2.py3-none-any.whl
then edit __init__.py to match the downloaded versions:
_SETUPTOOLS_VERSION = "18.4"
_PIP_VERSION = "7.1.2"
after which python3.4 -m ensurepip works as intended. Ensurepip is invoked automatically every time you create a virtual environment, for example:
pyvenv-3.4 py3
source py3/bin/activate
Hopefully RH will fix the broken Python3.4 yum package so that manual patching isn't needed.
Update: The python34 bug mentioned below has finally been fixed. It is a perfectly fine choice now.
Rather than using broken EPEL python34 packages, you can enable the IUS repo and have it work properly.
pip inside virtual environments
The main python34u and python35u IUS packages include the pyvenv tool (/usr/bin/pyvenv-3.4 or /usr/bin/pyvenv-3.5) that includes bundled wheels of pip and setuptools for bootstrapping virtual environments.
global pip
The python34u-pip and python35u-pip IUS packages include /usr/bin/pip3.4 and /usr/bin/pip3.5 respectively. These work just fine to install packages to the system site-packages directory.
yum install python34-pip
pip3.4 install foo
You will likely need the EPEL repositories installed:
yum install -y epel-release
Update 2019
I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.
sudo yum install epel-release
sudo yum install python34-pip
pip install package
Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.
Below are the steps I followed to install python34 and pip
yum update -y
yum -y install yum-utils
yum -y groupinstall development
yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum makecache
yum -y install python34u python34u-pip
python3.6 -v
echo "alias python=/usr/bin/python3.4" >> ~/.bash_profile
source ~/.bash_profile
pip3 install --upgrade pip
# if yum install python34u-pip doesnt work, try
curl https://bootstrap.pypa.io/get-pip.py | python
There is a easy way of doing this by just using easy_install (A Setuptools to package python librarie).
Assumption.
Before doing this check whether you have python installed into your Centos machine (at least 2.x).
Steps to install pip.
So lets do install easy_install,
sudo yum install python-setuptools python-setuptools-devel
Now lets do pip with easy_install,
sudo easy_install pip
That's Great. Now you have pip :)
Figure out what version of python3 you have installed:
yum search pip
and then install the best match. Use reqoquery to find name of resulting pip3.e.g
repoquery -l python36u-pip
tells me to use pip3.6 instead of pip3
On CentOS 7, the pip version is pip3.4 and is located here:
/usr/local/bin/pip3.4
