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).
