So when I was trying to install a package using pip, I encountered below error in my Ubuntu 20.04 LTS System. You might be getting the same error in different Linux version.

root@cyberithub:~# python3 -m pip install --user pipenv
/usr/bin/python3: No module named pip

While this error can come due to multiple reasons but in most of the cases you will see this error because of pip package not installed in your System. So to solve this kind of error, you need to simply install pip package from the default Repo. For example, in my case I have used apt-get install python3-pip command to install this package in my System. More about PIP.

If you are using RHEL/CentOS 7 based Systems, then all you need to do in to enable the EPEL Repo and then install the package by using yum install python3-pip command. For RHEL/CentOS 8 based Systems, you can use dnf install python3-pip command.

yum install python3-pip 
dnf install python3-pip

After successful installation, you can verify the package version by using pip --version command as shown below.

root@cyberithub:~# pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

After installing the package I again tried to run the earlier command then this time I noticed that the command worked successfully and now it is not throwing "/usr/bin/python3: No module named pip" error as shown below. Hope this helps !!
