How to Upgrade Pip3

How to update/upgrade a package using pip?

The way is

pip install <package_name> --upgrade

or in short

pip install <package_name> -U

Using sudo will ask to enter your root password to confirm the action, but although common, is considered unsafe.

If you do not have a root password (if you are not the admin) you should probably work with virtualenv.

You can also use the user flag to install it on this user only.

pip install <package_name> --upgrade --user

How do I update/upgrade pip itself from inside my virtual environment?

pip is just a PyPI package like any other; you could use it to upgrade itself the same way you would upgrade any package:

pip install --upgrade pip

On Windows the recommended command is:

python -m pip install --upgrade pip

How to upgrade `pip3.8` for `python-3.8.2`? I have two python versions`(python-3.6 and python-3.8.2)` and two `pip`s (`pip3 and pip3.8`) respectively

$ sudo pip3.8 install --upgrade pip

will give you the permissions you need.

If you aren't an administrator on the machine, you either need to su to one, or get them to run the command for you.

Attempting to upgrade pip from version 20.3.1 to version 21.3. How do I use the `--user` option?

Running pip install --upgrade --user pip (like pip is suggesting) will install pip on the user site packages (not the global). This works fine on some cases, but the upgraded package will only be available to the user who installed.

As I can read, your message seems harmless (it failed on a temporary file), if you run pip --version you should see the latest version. However, if that doesn't work, you may have to add the --user option to your command.

how to upgrade pip? getting this error while updating

You are getting a permission denied error. Run command prompt with administrative privileges (run as administrator). Then run the same pip upgrade command:

pip install --upgrade pip

How to upgrade pip in a dockerfile?

As you noticed, upgrading pip to the latest revision on each build of your Docker image doesn't guarantee a reproduciple build in the future. That is not a good idea.

The strategy to adopt depends on your needs. But you may consider the default pip version released with a specific Python version is a reasonable one. But to choose that, you may ensure your major Python release (3.6) is enough up-to-date. This is not your case here, since 3.6.1 is a very old release. The latest 3.6 is 3.6.13 and has been released 2 months ago (3.6 is still supported)

From https://www.python.org/downloads/

Python 3.6.13: Feb. 15, 2021
Python 3.6.2: July 17, 2017
Python 3.6.1: March 21, 2017

The reason behind updating pip on docker build is often the warning displayed by Pip when it is not the latest release

You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

This warning is useful when you have pip on your system, it has less value inside a built docker image. There is multiple way to disable this message, see How to suppress pip upgrade warning?:

CLI option

pip --disable-pip-version-check [normal stuff here]

Environment variable

export PIP_DISABLE_PIP_VERSION_CHECK=1

Pip config

pip config set global.disable-pip-version-check true

Pip config file (in $HOME/.config/pip/pip.conf)

[global]
disable-pip-version-check = True

pip install --upgrade pip and pip install --upgrade setuptools both failed with error code 1

I have had this issue before. pip requires the latest version of python to be working properly to work, however certain CPU architectures don't fully support it. you say your using an ARM based CPU which I think requires a different way of installing python. Pip will throw syntax errors when python is incompatible with your CPU arch. You may need to look into emulators or upgrading hardware.

Upgrading pip for different versions of python

Use the python 3.7 interpreter to run the command:

python3.7 -m pip install --upgrade pip

Or use the pip3.7 binary directly:

pip3.7 install --upgrade pip
