Question: I am trying to deploy my Django backend (using Django Rest Framework) on a Google Cloud VM instance. However, when I run pip install -r requirements.txt, I encounter the following error: Collecting asgiref==3.8.1 Using cached asgiref-3.8.1-py3-none-any.whl (23 kB) Collecting attrs==23.2.0 Using cached attrs-23.2.0-py3-none-any.whl (60 kB) ERROR: Could not find a version that satisfies the requirement Django==5.0.4 (from -r requirements.txt (line 3)) (from versions: 1.1.3, 1.1.4, 1.2, 1.2.1, 1.2.2, 1.2.3, 1.2.4, 1.2.5, 1.2.6, 1.2.7, 1.3, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.4, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.4.5, 1.4.6, 1.4.7, 1.4.8, 1.4.9, 1.4.10, 1.4.11, 1.4.12, 1.4.13, 1.4.14, 1.4.15, 1.4.16, 1.4.17, 1.4.18, 1.4.19, 1.4.20, 1.4.21, 1.4.22, 1.5, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, 1.5.7, 1.5.8, 1.5.9, 1.5.10, 1.5.11, 1.5.12, 1.6, 1.6.1, 1.6.2, 1.6.3, 1.6.4, 1.6.5, 1.6.6, 1.6.7, 1.6.8, 1.6.9, 1.6.10, 1.6.11, 1.7, 1.7.1, 1.7.2, 1.7.3, 1.7.4, 1.7.5, 1.7.6, 1.7.7, 1.7.8, 1.7.9, 1.7.10, 1.7.11, 1.8a1, 1.8b1, 1.8b2, 1.8rc1, 1.8, 1.8.1, 1.8.2, 1.8.3, 1.8.4, 1.8.5, 1.8.6, 1.8.7, 1.8.8, 1.8.9, 1.8.10, 1.8.11, 1.8.12, 1.8.13, 1.8.14, 1.8.15, 1.8.16, 1.8.17, 1.8.18, 1.8.19, 1.9a1, 1.9b1, 1.9rc1, 1.9rc2, 1.9, 1.9.1, 1.9.2, 1.9.3, 1.9.4, 1.9.5, 1.9.6, 1.9.7, 1.9.8, 1.9.9, 1.9.10, 1.9.11, 1.9.12, 1.9.13, 1.10a1, 1.10b1, 1.10rc1, 1.10, 1.10.1, 1.10.2, 1.10.3, 1.10.4, 1.10.5, 1.10.6, 1.10.7, 1.10.8, 1.11a1, 1.11b1, 1.11rc1, 1.11, 1.11.1, 1.11.2, 1.11.3, 1.11.4, 1.11.5, 1.11.6, 1.11.7, 1.11.8, 1.11.9, 1.11.10, 1.11.11, 1.11.12, 1.11.13, 1.11.14, 1.11.15, 1.11.16, 1.11.17, 1.11.18, 1.11.20, 1.11.21, 1.11.22, 1.11.23, 1.11.24, 1.11.25, 1.11.26, 1.11.27, 1.11.28, 1.11.29, 2.0a1, 2.0b1, 2.0rc1, 2.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.0.7, 2.0.8, 2.0.9, 2.0.10, 2.0.12, 2.0.13, 2.1a1, 2.1b1, 2.1rc1, 2.1, 2.1.1, 2.1.2, 2.1.3, 2.1.4, 2.1.5, 2.1.7, 2.1.8, 2.1.9, 2.1.10, 2.1.11, 2.1.12, 2.1.13, 2.1.14, 2.1.15, 2.2a1, 2.2b1, 2.2rc1, 2.2, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.6, 2.2.7, 2.2.8, 2.2.9, 2.2.10, 2.2.11, 2.2.12, 2.2.13, 2.2.14, 2.2.15, 2.2.16, 2.2.17, 2.2.18, 2.2.19, 2.2.20, 2.2.21, 2.2.22, 2.2.23, 2.2.24, 2.2.25, 2.2.26, 2.2.27, 2.2.28, 3.0a1, 3.0b1, 3.0rc1, 3.0, 3.0.1, 3.0.2, 3.0.3, 3.0.4, 3.0.5, 3.0.6, 3.0.7, 3.0.8, 3.0.9, 3.0.10, 3.0.11, 3.0.12, 3.0.13, 3.0.14, 3.1a1, 3.1b1, 3.1rc1, 3.1, 3.1.1, 3.1.2, 3.1.3, 3.1.4, 3.1.5, 3.1.6, 3.1.7, 3.1.8, 3.1.9, 3.1.10, 3.1.11, 3.1.12, 3.1.13, 3.1.14, 3.2a1, 3.2b1, 3.2rc1, 3.2, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5, 3.2.6, 3.2.7, 3.2.8, 3.2.9, 3.2.10, 3.2.11, 3.2.12, 3.2.13, 3.2.14, 3.2.15, 3.2.16, 3.2.17, 3.2.18, 3.2.19, 3.2.20, 3.2.21, 3.2.22, 3.2.23, 3.2.24, 3.2.25, 4.0a1, 4.0b1, 4.0rc1, 4.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.5, 4.0.6, 4.0.7, 4.0.8, 4.0.9, 4.0.10, 4.1a1, 4.1b1, 4.1rc1, 4.1, 4.1.1, 4.1.2, 4.1.3, 4.1.4, 4.1.5, 4.1.6, 4.1.7, 4.1.8, 4.1.9, 4.1.10, 4.1.11, 4.1.12, 4.1.13, 4.2a1, 4.2b1, 4.2rc1, 4.2, 4.2.1, 4.2.2, 4.2.3, 4.2.4, 4.2.5, 4.2.6, 4.2.7, 4.2.8, 4.2.9, 4.2.10, 4.2.11, 4.2.12, 4.2.13, 4.2.14, 4.2.15, 4.2.16) ERROR: No matching distribution found for Django==5.0.4 (from -r requirements.txt (line 3))  Here are the steps I performed cd Project_Backend python3 -m venv env sudo apt-get install python3-venv python3 -m venv env source ./env/bin/activate pip install -r requirements.txt  That's my requirements.txt asgiref==3.8.1 attrs==23.2.0 Django==5.0.4 django-cors-headers==4.4.0 djangorestframework==3.15.1 drf-spectacular==0.27.2 inflection==0.5.1 jsonschema==4.22.0 jsonschema-specifications==2023.12.1 PyYAML==6.0.1 referencing==0.35.1 rpds-py==0.18.1 sqlparse==0.4.4 typing_extensions==4.11.0 tzdata==2024.1 uritemplate==4.1.1  I am running Ubuntu on my Google Cloud VM.

Answer: Provide the full requirements.txt and Python version you plan to use to run the code. The errors indicate that PIP cannot install the version requested in the requirements.txt file as it conflicts with other requirements or is not supported by the Python version you have installed. If you are running something you didn't author, then your best bet is to install the Python version that the code was intended to run using the specified dependency versions frozen in the text file. Alternatively, you can go error-by-error and upgrade each dependency to the next supported version or go the opposite route and upgrade to the latest supported version for each. Dependency resolution can be tricky if you don't know which features of which dependency are being used, as things get deprecated, so using the correct versions helps. For Django, you can try removing the "==5.0.4" part from the requirements and see if PIP can find a compatible version for your project. You may need to do this one dependency at a time until you get it running. Look into PipEnv and Poetry, which help simplify dependency management.
