I am trying to install "cffi" with pip on MacOs 12.5 but I got an error
python : 3.8.10
pip : 22.2.2
Apple clang version 13.1.6 (clang-1316.0.21.2.5)
Command :
pip install cffi

gcc-11: error: unrecognized command-line option '-iwithsysroot/usr/include/ffi'
error: command '/opt/homebrew/bin/gcc-11' failed with exit status 1
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
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

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:

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 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
distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('cffi>=1.1.0')
pynacl needs cffi 1.1.0 above:
so while installing cffi1.11.5 i get the below error:

Can anyone help me with this?
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 to install gcc because it doesn't accept clang. It seems gcc doesn't ignore this unknown flag. I tried
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install mujoco_py
But it didn't help. Is there any way that gcc can ignore this unknown flag?
I finally find a solution.
First install clang-omp via brew install clang-omp. Then link clang-omp to gcc-7 via sudo ln -s /usr/local/bin/clang-omp /usr/local/bin/gcc-7. Then you should be able to run mujoco151. Note you may also need to brew uninstall glfw to solve a conflict.
I built Python 3.6 from source and am trying to install lxml. Trying to install it from pip gives the following error:

The same error is raised if I try to install Cython to compile lxml from source. I installed libxml2-dev and libxslt1-dev, but python3.6-dev, which is apparently also required, is not found in Raspbian repository. I added the following line to /etc/apt/sources.list:
deb http://ftp.de.debian.org/debian sid main
But when trying to install it afterwards, I receive the following error:
The following packages have unmet dependencies:
libdbus-1-3 : Breaks: dbus (< 1.9.16-1~) but 1.6.8-1+deb7u1 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
In fact, this error is raised on any package that is found in Debian repository that is not in Raspbian one. What can I do about this?
Since you installed Python from source, you should have the header files already. Should also use header files for the version that you built as opposed to the version in the package manager.
Either
Add the source code directory to includes used by GCC (gcc -I<dir>) or
Install the from source package in a system directory that is automatically included like /usr/include or /usr/local/include
The second option is probably easiest and should be possible from the standard configure/make scripts.
