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?
This question is related to

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
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
yum install python34-pip
pip3.4 install foo
You will likely need the EPEL repositories installed:
yum install -y epel-release
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.
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.
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.
On CentOS 7, the pip
version is pip3.4
and is located here:
/usr/local/bin/pip3.4
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.
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
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 :)
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.
