I am trying to run Quantlib-Python on a Macbook with M1 processor (Big Sur v11.3) following https://www.quantlib.org/install/macosx-python.shtml. I have managed to install Quantlib 1.22 and Python 3.9.4 via homebrew:
Pouring quantlib--1.22.arm64_big_sur.bottle.tar.gz into "/opt/homebrew/Cellar/quantlib/1.22"
However when I then try to install Quantlib-Python through pip I get:
ERROR: Could not find a version that satisfies the requirement QuantLib (from versions: none)
ERROR: No matching distribution found for QuantLib
From this it seems that whilst Quantlib 1.22 is ready for arm-based OSX, QuantLib-Python isn't.
Then I am trying to install from a released version as per the above link:
tar xzf QuantLib-SWIG-1.22.tar.gz
cd QuantLib-SWIG-1.22/Python
export CXXFLAGS='-O2 -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9'
export LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9'
python setup.py build
But I get the following error:
cd QuantLib-SWIG-1.22/Python
export CXXFLAGS='-O2 -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9'
export LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9'

I have tried quite a few workarounds for the boost issue, and looked over lots of other question/answers but yet to find a fix. Is it an issue with the flags? Has anyone had any luck getting QuantLib-Python to work on M1-based OSX?
Below worked for me on a MBP M1 Max:
brew install boost
brew install quantlib
download QuantLib-SWIG-1.24.tar
tar xzfv QuantLib-SWIG-1.24.tar
cd QuantLib-SWIG-1.24/Python

I am trying to install "cffi" with pip on MacOs 12.5 but I got an error

I also did some tips which mentioned in the following link but it didn't work for me.
pip cffi package installation failed on osx
After reading cffi documents, I find out that,"/opt/homebrew/bin/gcc-11" is gcc, and not clang and cffi doesn't explicitly support gcc on MacOS.
So, I added the following lines to ~/.bash_profile and it worked
# Set Clang as the default compiler for the system
export CC=clang

I tried different solutions provided by Stackoverflow such as:

Any suggestions or comments to resolve this?

You don't have mysql C libraries installed on your Mac OS, there are multiple options to install it.
You can install it easy fi you have brew installed on your Mac OS, or google for other options to install the libs using your env.

enter code hereI'm trying to install paramiko module in my linux server. The pip is blocked on the server, So i am manually copying the package zips and installing them from setup.py
when i try installing paramiko i get
error: Could not find suitable distribution for Requirement.parse('pynacl>=1.0.1')
so i download the PyNaCl package, but i get

pynacl needs cffi 1.1.0 above:
so while installing cffi1.11.5 i get the below error:

If this is a Debian or Ubuntu machine,
sudo apt install libffi-dev
and then try again.
For other distributions, the installation method and package name may be different.
I have downloaded Mayan EDMS-Electronic Document Management System from GitHub and I configured project using Django server. I had added the required libraries based on requirement. Now the project runs with error

Then I tried to install tesseract using the command -->pip install tesseract-ocr.

please help me to solve this issue. Thanks in advance.
Tesseract is installed on the OS using the apt-get command. The command you are using (PIP) is for installing Python packages, that is the reason for the error.

i have kubuntu 15.10 with python2.7 and python 3.4m installed
if i install cxfreeze with sudo apt-get cx_freeze it is installed with no issues but the problem is when i compile my python modules the are compiled for python2.7 not python 3
So i am trying to build cx_freeze from source and i am facing this error when i run sudo python3 setup.py build
here's the error

Install zlib1g-dev :
sudo apt install zlib1g-dev
then install cx_freeze for python:
pip install cx_freeze
I've tried that on Ubuntu 18.04 and Python 3.6 and worked.
I had exactly the same problem. As suggested in this answer you just need to install the dependencies first:
pip3 install zlib1g-dev
Then sudo python3 setup.py build
