I am interrested in knowing the recommended way to install pip3 for python3.6 (as of today, may 2018) on current version of centos7 (7.5.1804) and the accepted answer of How to install pip in CentOS 7? seems to be outdated because:
yum search -v pip
outputs (among other things):
python2-pip.noarch : A tool for installing and managing Python 2 packages
Repo : epel
python34-pip.noarch : A tool for installing and managing Python3 packages
Repo : epel
and python34-pip
seems to be a (newer?) simpler way than the accepted answer of How to install pip in CentOS 7? :
sudo yum install python34-setuptools
sudo easy_install-3.4 pip
But since the versions of python installed on my machine are 2.7.5 and 3.6.3 why is it python34-pip and not python36-pip ? Is pip the same for 3.4+ (up to current 3.6.3) ?
Is pip the same for 3.4+
No, it's not. A single pip
installation serves a single Python distribution (pip2.7
/pip3.4
/pip3.5
etc).
Since Python 3.5, pip
is already bundled with the python distribution, so you can just run python3.6 -m pip
instead of pip
.
Python 3.6 is not available in CentOS 7 vanilla repo. I usually resort to IUS repo when needing to install a fresh Python on CentOS. It always has the most recent Python version, the current one being 3.6.5. It also offers a correspondent pip
package.
$ yum install https://centos7.iuscommunity.org/ius-release.rpm
$ yum install python36u python36u-devel python36u-pip
Unfortunately, IUS doesn't offer a package for Python 3.7 yet so if you are looking for Python 3.7 on CentOS 7, building from source is your only option.
yum
is not an optionYou should prefer the bootstrapping solution described in this answer as it is the most reliable way to get a working pip
installed.
