Quickfix for Python Library installation fails in MacOS

I am trying to install quickfix 1.15.1 (the current latest version available) in MacOS.
OS version is Ventura 15.1. Chip is Apple M2.
Python version is 3.9.6. Clang version is 14.0.0.
But the installation gets failed.
The steps I followed is as follows.
Tried to install using pip3 install quickfix. It was not successful.
Downloaded the source package from pypi and tried to install the package using pip3 install . and pip3 install . --no-binary=:all --user --no-cache-dir. It was not successful.
Cloned the C++ quickfix source code from github and tried to install the library using the commands ./boostrap, ./configure --with-python3 and sudo make install. It was not successful too.
The error I get when trying to install the library in all the above three steps is as follows.

Went through different issue threads and docs, but could not find a solution yet. Found this similar stack overflow post as well. But a solution could not be found there too.

Fix error with skforecast and pyproject.toml-based projects

I'm trying to run: from skforecast.ForecasterAutoreg import ForecasterAutoreg and i have this error "from skforecast.ForecasterAutoreg import ForecasterAutoreg
ModuleNotFoundError: No module named 'skforecast'"
I run C:\Users\Yanina\Prueba>pip3 install skforecast and this happens
building 'statsmodels.tsa._stl' extension
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for statsmodels
Failed to build statsmodels
ERROR: Could not build wheels for statsmodels, which is required to install pyproject.toml-based projects
WARNING: You are using pip version 22.0.4; however, version 22.2 is available.
You should consider upgrading via the 'C:\Users\Yanina\AppData\Local\Programs\Python\Python310\python.exe -m pip install --upgrade pip' command.
When i run pip for pyproject.toml it apparently works just fine.
So i think the issue is with skforecast but i dont know how to fix it.

when installing airflow, it occurs: subprocess-exited-with-error

os: centos7.6
python 3.8
occur error:
Collecting airflow

error: metadata-generation-failed

maybe this help
python -m pip uninstall setuptools
pip install setuptools
pip install airflow

This is simply saying the build tool setup.py fails to build from source.
I am not so technical in the aspect of building from source, so I can't tell you exactly what to do with your .tar.gz file to make it all right.
If you have pip installed on the machine (which I assume you do), then simply type:
pip install apache-airflow
The long version:
python3 -m pip install apache-airflow
If you intend to use celery together with Apache Airflow, I suggest:
python3 -m pip install apache-airflow[celery] for full installation.
Refer to the documentation of Apache Airflow for more info.

Issue with pip install in virtual environment - Cargo, the Rust package manager, is not installed or is not on PATH

I am using a python virtual environment to work on a project. After setting up my venv and pulling from git I tried to pip install -r requirements.txt but am getting an error below.

I am using Python version 3.10.2, pip version 22.0.4.
Any idea how to fix this? I installed rust but no fix.
I am not getting the errors below after moving my virtual enviroment to local.

faced the similar problem. after installing 64bit version of python everything is working fine.

The above error is caused by a rust package
pywinpty
all you need do is to remove it from requirements.txt file
and redeploy your app.

Simply install the dependency:
curl https://sh.rustup.rs -sSf | sh
Source: https://doc.rust-lang.org/cargo/getting-started/installation.html

Try installing the rust programming language. It seems like you have a dependency that uses rust. I recommend using brew on OSX.
brew install rust
Otherwise use the rust install page. You can check that rust is installed properly with:
rustc --version
Once you are finished try again to pip install your requirements file.

Cannot install pyansys using pip install

I am on Pycharm and wish to install the pyansys package, but I keep getting this error:
Collecting pyansys

To use PyAnsys you need to install the applicable packages for your

- ``pip install ansys-dpf-core``

So I went ahead and installed all but one of those packages. I also installed cython. The only package that cannot be installed is ansys-dpf-reader and here is its error message
ERROR: Could not find a version that satisfies the requirement ansys-pdf-reader (from versions: none)
ERROR: No matching distribution found for ansys-pdf-reader
What is going on?

So it seems like 'ansys-dpf-reader' was changed to 'ansys-dpf-post' and the 'pyansys' is not a pacakge anymore, but has now expanded into these 5 packages. Installing all of them will allow the normal use of the old pyansys.
