Upgrade python packages from requirements.txt using pip command

Upgrade python packages from requirements.txt using pip command

I already answered this question here. Heres my solution:

Because there was no easy way for upgrading package by package, and updating the requirements.txt file, I wrote this pip-upgrader which also updates the versions in your requirements.txt file for the packages chosen (or all packages).

Installation

pip install pip-upgrader

Usage

Activate your virtualenv (important, because it will also install the new versions of upgraded packages in current virtualenv).

cd into your project directory, then run:

pip-upgrade

Advanced usage

If the requirements are placed in a non-standard location, send them as arguments:

pip-upgrade path/to/requirements.txt

If you already know what package you want to upgrade, simply send them as arguments:

pip-upgrade -p django -p celery -p dateutil

If you need to upgrade to pre-release / post-release version, add --prerelease argument to your command.

Full disclosure: I wrote this package.

you can try:

pip install --upgrade --force-reinstall -r requirements.txt

You can also ignore installed package and install the new one :

pip install --ignore-installed -r requirements.txt

Upgrade python packages from requirements.txt using pip command

No. Your requirements file has been pinned to specific versions. If your requirements are set to that version, you should not be trying to upgrade beyond those versions. If you need to upgrade, then you need to switch to unpinned versions in your requirements file.

Example:

lxml>=2.2.0

This would upgrade lxml to any version newer than 2.2.0

lxml>=2.2.0,<2.3.0

This would upgrade lxml to the most recent version between 2.2.0 and 2.3.0.
