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'm trying to prevent this warning every time I create a fresh .venv:
> /Users/pi/.pyenv/versions/3.10.0/bin/python -m venv .venv
> . .venv/bin/activate
> pip install ipykernel # or anything
WARNING: You are using pip version 21.2.3; however, version 22.2.2 is available.
You should consider upgrading via the '/Users/pi/code/foo/.venv/bin/python -m pip install --upgrade pip' command.
Somehow pyenv has populated my fresh .venv with an out-of-date pip.
If I execute the suggested command it will upgrade my .venv's pip. But I don't want to be doing that every time I create a .venv.
I figured this might fix it, but it doesn't:
> /Users/pi/.pyenv/versions/3.10.0/bin/python -m pip install --upgrade pip
Requirement already satisfied: pip in /Users/pi/.pyenv/versions/3.10.0/lib/python3.10/site-packages (22.2.1)
Collecting pip

Installing collected packages: pip
Attempting uninstall: pip
Found existing installation: pip 22.2.1
Uninstalling pip-22.2.1:
Successfully uninstalled pip-22.2.1
Successfully installed pip-22.2.2
What is actually happening when I execute the above command? I was expecting it to update the pip for the python version created/maintained by pyenv. Which it seems to be doing:
🧢 pi#pPro18-4 ~/.pyenv/versions/3.10.0
> find . -name 'pip*'
./bin/pip3
./bin/pip
./bin/pip3.10
./lib/python3.10/site-packages/pip
./lib/python3.10/site-packages/pip-22.2.2.dist-info
🧢 pi#pPro18-4 ~/.pyenv/versions/3.10.0
> ./bin/pip --version
pip 22.2.2 from /Users/pi/.pyenv/versions/3.10.0/lib/python3.10/site-packages/pip (python 3.10)
So why isn't this pip getting copied into my .venv when I create it?
I thought that was the way .venv creation worked.
How to clean up my pyenv Python installation so that it spawns up-to-date .venvs?
EDIT:
Insight from #python on IRC/Libera:
grym: I don't think you can; i just get in the habit of python -m venv somevenv && somevenv/bin/python -m pip install --upgrade pip setuptools wheel
jinsun: python -m venv --upgrade-deps .venv is a simple solution if you were just annoying by the pip warning (...) it is updating the pip inside the venv, forget about the base python, I don't even have pip in the base python
This is the use case for pyenv-hooks
pyenv-hooks are scripts that are executed by pyenv whenever certain commands are run. You can create hooks for regular commands like: exec, rehash, which, but it can also be a plugin command, like virtualenv. The scripts can be written in any language.
Here is the wiki with official instructions.
You can have a hook by creating a script at the following location:
$PYENV_ROOT/pyenv.d/<hook-name>/<your-script-name>
For example, to create a hook that upgrades pip, create a new script within this path:
$PYENV_ROOT/pyenv.d/virtualenv/after.bash
With contents:
after_virtualenv 'PYENV_VERSION="$VIRTUALENV_NAME" pyenv-exec pip install --upgrade pip'
after_virtualenv is the command that tells pyenv when to execute. First, it sets the pyenv version to the name of the virtualenv we just created. with the variable $VIRTUALENV_NAME. Then it upgrades pip itself.
More details in this article.
I originally posted it as a comment, but was suggested to make it a proper answer.
An easier approach is to use the upgrade-deps flag when you create a virtual environment. Like this:
python3 -m venv --upgrade-deps .venv
It was added on python3.9, and according to the official docs:
--upgrade-deps
Upgrade core dependencies (pip, setuptools) to the latest version in PyPI
So, in other words, it will install pip and upgrade right away.
I use a different virtual environment for every project I work on (using pyenv and pyenv-virtualenv), and I often come across a message like then when installing a python package using pip:
WARNING: You are using pip version 21.1.3; however, version 21.2.4 is available.
You should consider upgrading via the '/Users/.../.pyenv/versions/3.9.6/envs/sdge/bin/python -m pip install --upgrade pip' command.
However, when I run the pip install --upgrade pip command, it only upgrades pip in that particular virtual environment (which is expected, and that is behavior that I want), and it is annoying to see this across all my different virtual environments.
Is there some kind of shortcut (either with pyenv, pip, or the shell) that I could use to run pip install --upgrade pip on every virtual environment?
I don't use pyenv so I created this code after reading documentation and source code (not tested):
for env in $(pyenv virtualenvs --bare --skip-aliases); do
pyenv activate $env
pip install --upgrade pip
pyenv deactivate
done
I'm trying to set up a virtual environment. I have a Mac, using Mac OS Big Sur 11.1. I have installed the latest stable version of python, but when I enter this command into the terminal window
-m pip install pipenv pip --upgrade
I get the following error
zsh: command not found: -m
before, it would say
"No module named pip"
Do I have to install pip separately with
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
I thought pip was included by default when you install python? I think I might have pip because when I type
python3 -m pip
into the command line, I get a long list of commands (install packages, download packages, etc.) General options... Thus should I install pip? one person on reddit said,
Pip is not necessarily included with any version of Python. In many
distributions, it must be installed separately.
If python3 -m pip works, then you have a bad install, not a missing
one.
thus did I incorrectly install python? When I was installing it there was no option to
"add python to PATH"
Do I have to do this on a mac? If I input
python3 -V
in terminal, I get
Python 3.9.2
Thanks
i solved this by running,
pip3 install pip --upgrade
I want to upgrade pip, using cmd. But it doesn't.
Release was 19.0.3.
(There was an update on the latest version side like "setuptools" and i wanted to update to 19.3 using cmd but it didn't work and i did it manually.)
Maybe path can be wrong, so i shared paths.
pip is just a PyPI package so you can use it to upgrade itself.
pip install --upgrade pip
On Windows:
python -m pip install --upgrade pip
My console:
desarrollador#desarrollador-HP-14-Notebook-PC1:~$ pip freeze

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)
