DEPRECATION: dlib is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Unable to install autodock vina (potentially due to boost)

As part of a script I am writing, I need to install the package autodock vina for the purpose of ligand and protein binding. Every time I attempt to "pip install vina", I recieve an error message " ValueError: Boost library location was not found!". Upon attempting to install boost manually, I have been unable to run the bootstrap file, as it does not make the b2 folder that online tutorials say it will make.
To resolve this issue, I installed conda, and made an active environment with every single prerequisite, including boost, installed. I have checked for the version of all of these prerequisites and confirmed their existence, as well as double and triple-checking that I am in the write active environment. Upon installation, I either get the same issue (using conda install vina) or when using "conda install -c bioconda autodock-vina", I get a message saying that the package does not exist (despite adding cforge and bioconda as active package handlers, and the existence of said package is clearly documented online). Does anyone have any suggestions? I've been attempting to install this piece of software for 3 days and I've completely exhausted the documentation, as well as all other similar question answers, with nothing working.

I also get this error. I asked ResearchGate how to solve this problem and Cheng Shen adviced to use WSL/WSL2 to simulate a Linux environment and then run conda install -c bioconda vina (or another command like this)
What I did.
Install WSL and Ubuntu on Windows 2. Run code . in WSL terminal (for installing VS Code [recommended])
Install Anaconda/Miniconda following this guide
Type conda install -c bioconda vina in Ubuntu terminal (bioconda channel will download all required packages - boost, swig, etc.)
Vina should be successfully installed ( vina --version in WSL Terminal to check)
I found it much easier to install packages for docking via WSL and use VS Code to run scripts there. It's VERY easier than trying to solve this problem by configuring boost for Windows. If you have any questions you can ask me in ResearchGate.

Follow the steps below to install face_recognition python package on Windows 10.
The instruction has been tested on Windows 10 64bit, python 3.9.
Step 1
Download CMake installation package for your OS from official site
Step 2
Install downloaded CMake installation package. Please make sure that Add CMake to system PATH option has been selected during the installation.
Step 3
Reboot your OS (restart computer)
Step 4
Run pip install dlib
It tooks several minutes so be prepared to wait
Step 5
If it completes without any errors, you're all set. Run pip install face_recognition to install face_recognition.
Result

Fixed it. I had to modify my Visual Studio install from Start menu programs, and include latest MSVC and include Windows 10 SDK under Individual Components

This is my setup:
Alpine Linux 3.6.2
Python 3.6.3
pip 19.1
wheel 0.33.1
setuptools 41.0.1
Any idea what could be the problem, or how to solve it?
Thanks for the help in advance!

I did not find any uniform solution to this problem. You can try the following troubleshooting steps. one of them should work.
Upgrade the pip version.
Change the library/package version.
If you are installing from source, try a different .whl package or use tar.gz.
Use --no-use-pep517 with your pip install command (didn't work for me though, but I see it worked for some).

I got the same error with a different library and --no-use-pep517 did not help. However this did:
python -m pip install --upgrade pip

xcode-select error during pyobjc-core installation

I am trying to install pyobjc-core which is a requirement for pyautogui. I am getting the below error while installing. I have already updated setuptools using
pip3 install --upgrade setuptools
and also using
sudo python3 ez_setup.py
I am on OSX Yosemite and using Python 3.5.
I see that the code below has a requirement for xcode. Could that be the reason and why would xcode be needed for this installation?
pip3 install pyobjc-core

The error is clear: you need xcode...
It's silly but unfortunately there are these developer tools that are tied to it, and since many packages require dev tools (in your specific case xcodebuild needs it) you have to install xcode (anyway it's free)
