Upgrade python packages from requirements.txt using pip command
package, pip, python, requirements.txt
Solution
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.
Problem
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).
