I know the newer versions of python come with pip installed. So 'sudo apt-get install python3-pip' gives me that it is installed saying that it is the latest version, then why does 'pip install django' gives an error saying pip is not insatlled? Namely this:
The program 'pip' is currently not installed. You can install it by typing:
sudo apt-get install python-pip
I again run 'sudo apt-get install python-pip' (for python 2.7) which installs version 1.5. So i try pip install -U pip and it downloads the package marked 7.1 and succesfully installs. However on checking the version again it is still 1.5
You can install pip with the help of get-pip.py script.
you can download this script and execute on your terminal "python get-pip.py".
it will install pip on your system.
you can also use curl to download get-pip.py script-
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py".
To verify the installation you can use-
pip --help
pip -V

I'm trying to install software in kali that requires my Python version to be 3.6.9 or lower.
I also need to install pip to install requirements.
I have Python3.6.9 installed and when I run #apt-get install python3-pip
It also updates my Python version to 3.10
Is there a way to get pip installed without upgrading my python version?
If you are looking to install pip on to an existing python installation, which did not come with pip pre-installed, you can use the bootstrap script to that.
Like
curl -sSL https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py #or python3
If you want to update the pip version installed, then you can use
python -m pip install --upgrade pip
I set up a VMware machine under Windows 10, running Ubuntu 20.04.
The first thing I did after the installation was to install pip:
sudo apt install python3-pip
I then did:
sudo pip3 install --upgrade pip3
to which I got an error saying that the package pip3 doesn't exist. So I did:
sudo pip3 install --updgrade pip
which finished and installed pip 21.0.1
Now if I run pip3 with sudo, I have to type sudo pip3, but for a non-root user I have to use pip insted of pip3
sudo pip3 --version and sudo pip --version and pip --version return the same:
pip 21.0.1 from /usr/local/lib/python3.8/dist-packages/pip (python 3.8)
But pip3 --version returns: bash: /usr/bin/pip3: No such file or directory
I just want to use the command pip3 both with and without root privilige and I don't understand what's happening here.
bash: /usr/bin/pip3: No such file or directory
This is because bash still remembers where it saw pip3 last time and the place was changed from /usr/bin/pip3 to /usr/local/bin/pip3. To clear its memory run hash -r. See command hash in bash manual.
I'm trying to install pip for Python 3.8 on an Ubuntu 18.04 LTS.
I know this has been asked way too many times. But those questions do not concern keeping Ubuntu's defaults specifically. And the answers on those questions either don't work or go on to suggest something so drastic that it would break the system - e.g. change default python3 version from 3.6 to 3.8. You SHOULDN'T!
So far, I've been able to install python3.8 successfully using the PPA - ppa:deadsnakes/ppa:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.8
Changed python command from python2 to python3.8 using update-alternatives:
update-alternatives --remove python /usr/bin/python2
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 10
Now, I get python 3.8 when I run python --version:
Python 3.8.5
The problem is, I still can't install pip for Python 3.8.
If I try to install python3-pip, it installs pip for Python 3.6 since python3 still points to python3.6.9, and I intend to keep it that way.
Try installing python-pip, and it will install pip for Python 2.7.
Also there's no such package as python3.8-pip, so I can't install it like:
sudo apt install python3.8-pip
Output:
E: Unable to locate package python3.8-pip
E: Couldn't find any package by glob 'python3.8-pip'
E: Couldn't find any package by regex 'python3.8-pip'
What can I do to install pip for Python 3.8 on an Ubuntu 18.04?
While we can use pip directly as a Python module (the recommended way):
python -m pip --version
This is how I installed it (so it can be called directly):
Firstly, make sure that command pip is available and it isn't being used by pip for Python 2.7
sudo apt remove python-pip
Now if you write pip in the Terminal, you'll get that nothing is installed there:
pip --version
Output:
Command 'pip' not found, but can be installed with:
sudo apt install python-pip
Install python3.8 and setup up correct version on python command using update-alternatives (as done in the question).
Make sure, you have python3-pip installed:
(This won't work without python3-pip. Although this will install pip 9.0.1 from python 3.6, we'll need it.)
sudo apt install python3-pip
This will install pip 9.0.1 as pip3:
pip3 --version
Output:
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)
Now, to install pip for Python 3.8, I used pip by calling it as a python module (ironic!):
python -m pip install pip
Output:
Collecting pip

Installing collected packages: pip
Successfully installed pip-20.2
It looks like, when I called pip (which was installed for Python 3.6, BTW) as a module of Python 3.8, and installed pip, it actually worked.
Now, make sure your ~/.local/bin directory is set in PATH environment variable:
Open ~/.bashrc using your favourite editor (if you're using zsh, replace .bashrc with .zshrc)
nano ~/.bashrc
And paste the following at the end of the file
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
PATH="$HOME/.local/bin:$PATH"
fi
Finally, source your .bashrc (or restart the Terminal window):
source ~/.bashrc
Now if you try running pip directly it'll give you the correct version:
pip --version
Output:
pip 20.2 from /home/qumber/.local/lib/python3.8/site-packages/pip (python 3.8)
Sweet!
As suggested in official documentation you can try with get-pip.py.
wget https://bootstrap.pypa.io/get-pip.py
python3.8 get-pip.py
This will install pip as pip3.8
Another solution would be to install the pip that is in apt. sudo apt install python3-pip. The version of the pip that it installs is for all versions of Python not only for version 3.6 once installed you just need to update the pip with the command python3.8 -m pip install pip and he will be install the latest version of pip for Python.
I would not advise you to remove Python2 because it is an important module for the system you should just create a permanent "alias" in .bashrc for Python3 I did like this alias python="python3.8.
# install py3.8 and dependencies for the pip3 bootstrap script
add-apt-repository -y ppa:deadsnakes/ppa && \
apt install -y python3.8 python3.8-distutils
# download and run the pip3 bootstrap script
cd /tmp && wget https://bootstrap.pypa.io/get-pip.py && \
python3.8 /tmp/get-pip.py
# use pip py3.8 module to install python packages
python3.8 -m pip install numpy pandas
Install python v3.8 as python
RUN apt update --fix-missing && \
apt install python3.8 -y && \
update-alternatives --install /usr/bin/python python /usr/bin/python3.8 10
Install pip for python 3.8
RUN apt install python3-pip -y && \
python -m pip install --upgrade pip
I did this a couple days ago and I struggled a lot with it but I finally got it working, so I wrote up what I did as a blog post.
In the end I think I may have done mostly the same things as the above answer, but if you got lost following it, maybe my screenshots etc will help.
Here's the tl;dr of the process I did:
Uninstall python3-pip & python-pip using apt
Remove the old pip files from /usr/local/bin
Reinstall python3-pip using apt
Add $HOME/.local/bin to your $PATH (also restart your shell to make sure you did this right)
On ubuntu server
sudo apt install python -y

I've had to install Python packages and libraries using pip, but every time I do, it says I'm using an older version of pip, and that v18.1 is available by running the command
python -m pip install --upgrade pip
When I run this command, it just says the same thing. It apparently can't update itself because it's outdated. Is there any way to get around this, maybe by manually updating it?
Thanks in advance, community!
Update: The OS I'm using is currently Windows 10 and Python 3.6.4. The following screenshot is what outputs when running the command.
Upgrading pip
On Linux or macOS:
pip install -U pip
On Windows:
python -m pip install -U pip
Try with "python -m pip install --upgrade pip --user"
It worked with me and I am with Win10.
If you are on linux try this -
sudo su root
apt-get purge -y python-pip
wget https://bootstrap.pypa.io/get-pip.py
python ./get-pip.py
apt-get install python-pip
or
sudo -H pip3 install --upgrade pip
sudo -H pip2 install --upgrade pip
On OS X this worked for me
python -m pip install --upgrade pip
I have my deployment system running CentOS 6.
It has by default python 2.6.6 installed. So, "which python" gives me /usr/bin/python (which is 2.6.6)
I later installed python3.5, which is invoked as python3 ("which python3" gives me /usr/local/bin/python3)
Using pip, I need to install a few packages that are specific to python3. So I did pip install using:-
"sudo yum install python-pip"
So "which pip" is /usr/bin/pip.
Now whenever I do any "pip install", it just installs it for 2.6.6. :-(
It is clear that pip installation got tied to python 2.6.6 and invoking pip later, only installs packages for 2.6.6.
How can I get around this issue?
If pip isn’t already installed, then first try to bootstrap it from the standard library:
$ python3.5 -m ensurepip --default-pip
If that still doesn’t allow you to run pip:
Securely Download get-pip.py.
Run sudo python3.5 get-pip.py.
Now you can use pip3 to install packages for python3.5. For example, try:
$ sudo pip3 install ipython # isntall IPython for python3.5
Alternatively, as long as the corresponding pip has been installed, you can use pip for a specific Python version like this:
$ python3.5 -m pip install SomePackage # specifically Python 3.5
References:
Ensure you can run pip from the command line
work with multiple versions of Python installed in parallel?
I have python 3.6 and 3.8 on my Ubuntu 18.04 WSL machine. Running
sudo apt-get install python3-pip
pip3 install my_package_name
kept installing packages into Python 3.6 dist directories. The only way that I could install packages for Python 3.8 was:
python3.8 -m pip install my_package_name
That installed appropriate package into the Python 3.8 dist package directory so that when I ran my code with python3.8, the required package was available.
Example of how to install pip for a specific python version
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
/opt/local/bin/python2.7 get-pip.py
Script is from official doc: https://pip.pypa.io/en/stable/installing/
On Ubuntu 18.04.1 LTS I wanted to install pip for my second python version (python3) and the following command did the trick for me:
$ sudo apt install python3-pip
