How do I upgrade all my python packages from requirements.txt file using pip command?
tried with below command
$ pip install --upgrade -r requirements.txt
Since, the python packages are suffixed with the version number (Django==1.5.1) they don't seem to upgrade. Is there any better approach than manually editing requirements.txt file?
EDIT
As Andy mentioned in his answer packages are pinned to a specific version, hence it is not possible to upgrade packages through pip command.
But, we can achieve this with pip-tools using the following command.
$ pip-review --auto
this will automatically upgrade all packages from requirements.txt (make sure to install pip-tools using pip install 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.
I already answered this question here. Here's 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
Since I couldn't do that using bash, I wrote a python module to create a new requirements file with no versions and use it:
data = open('requirements-prod.pip', 'r')
data2 = open('requirements-prod-no-version.pip', 'w')
for line in data.readlines():
new_line = line[:line.index('==')]
data2.write(new_line + '\n')
data2.flush()
Then install the libs from the new file pip install -U -r requirements-prod-no-version.pip
Finally freeze the versions to the original file pip freeze > requirements-prod.pip
If you install anything in your django project and after installation you want to update your requirement file this command can update you requirement.txt file
pip freeze > requirements.txt
if your requirement file not exist in you project you can use this command for make new requirement.txt file
pip freeze > requirements.txt
I edit the requirements.txt as below and run $sh ./requirements.txt
pip install -U amqp;
pip install -U appdirs;
pip install -U arrow;
pip install -U Babel;
pip install -U billiard;
pip install -U celery;
