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
$ pip-review --auto
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.
This would upgrade lxml to any version newer than 2.2.0
This would upgrade lxml to the most recent version between 2.2.0 and 2.3.0.
