How to upgrade all the packages in your Django application in one fell swoop
Conclusion

I was just working on a Django application, and one of my djLint dependencies was not up to date. It resulted in the following error when I ran the pip install -r requirements.txt command:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
djlint 1.36.4 requires click>=8.0.1, but you have click 7.1.2 which is incompatible.
djlint 1.36.4 requires pyyaml>=6, but you have pyyaml 5.3.1 which is incompatible.
djlint 1.36.4 requires tqdm>=4.62.2, but you have tqdm 4.47.0 which is incompatible.
sphinx 8.1.3 requires Jinja2>=3.1, but you have jinja2 2.11.2 which is incompatible.

I ran the command pip install --upgrade -r requirements.txt to find out what version upgrade I needed for the click package. The following was returned in Terminal:

ERROR: Cannot install -r requirements.txt (line 3), click==7.1.2 and djlint==1.36.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested click==7.1.2
    djlint 1.36.4 depends on click>=8.0.1
    The user requested click==7.1.2
    djlint 1.36.4 depends on click>=8.0.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict

I replaced 7.1.2 with 8.0.1 in requirements.txt. I could have upgraded to the latest version of click by running the following:

pip install --upgrade click

This time, the following version was installed:

Requirement already satisfied: click in /Users/mariacam/.pyenv/versions/3.13.0/lib/python3.13/site-packages (8.0.1)
Collecting click
  Using cached click-8.1.8-py3-none-any.whl.metadata (2.3 kB)
Using cached click-8.1.8-py3-none-any.whl (98 kB)
Installing collected packages: click
  Attempting uninstall: click
    Found existing installation: click 8.0.1
    Uninstalling click-8.0.1:
      Successfully uninstalled click-8.0.1
Successfully installed click-8.1.8

I replaced "8.0.1" with "8.1.8". Then I ran pip install --upgrade -r requirements.txt again.

After I had fixed the click issue, and ran pip install --upgrade -r requirements.txt, the following was returned:

ERROR: Cannot install -r requirements.txt (line 3), PyYAML==5.3.1 and djlint==1.36.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested PyYAML==5.3.1
    djlint 1.36.4 depends on pyyaml>=6
    The user requested PyYAML==5.3.1
    djlint 1.36.4 depends on pyyaml>=6

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict

Again, I upgraded PYAML by running pip install --upgrade PyYAML, and the following was returned:

Requirement already satisfied: PyYAML in /Users/mariacam/.pyenv/versions/3.13.0/lib/python3.13/site-packages (6.0.2)

I replaced "5.3.1" with "6.0.2" in requirements.txt, and then ran pip install --upgrade -r requirements.txt again. The following was returned:

ERROR: Cannot install -r requirements.txt (line 3), djlint==1.36.4 and tqdm==4.47.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested tqdm==4.47.0
    djlint 1.36.4 depends on tqdm>=4.62.2
    The user requested tqdm==4.47.0
    djlint 1.36.4 depends on tqdm>=4.62.2

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict

I upgraded tqdm by running pip install --upgrade tqdm, and the following was returned:

Requirement already satisfied: tqdm in /Users/mariacam/.pyenv/versions/3.13.0/lib/python3.13/site-packages (4.67.1)

I replaced "4.62.2" with "4.67.1" in requirements.txt, and ran pip install --upgrade -r requirements.txt again. This time no version conflicts were returned:

Conclusion

I technically was not able to upgrade all packages in my requirements.txt file in "one fell swoop" (it is not possible), but I did get the information I needed in "one fell swoop at a time". The pip install --upgrade -r requirements.txt command informed me what dependency conflicts existed in my requirements.txt file by returning an ERROR: ResolutionImpossible error, and the pip install --upgrade <packagename> command updated an individual package to its latest version.
