╰─> lightgbm
note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
There is a workaround for this?

When you run pip install lightgbm and see this message in logs:
Building wheels for collected packages: lightgbm
it means that there is not a pre-compiled binary (i.e. wheel) available matching your platform (operating system + architecture + Python version), and that LightGBM needs to be built from source.
lightgbm is a Python package wrapping lib_lightgbm, a C++ library with a C API. So "built from source" for lightgbm means compiling that C/C++ code, which for LightGBM requires:
C and C++ compilers
the CMake build system
an installation of OpenMP
Those components are the "CMake and all required dependencies" referred to in the error message.
On macOS, you should already have a C/C++ compiler installed (clang) by default. To get CMake and OpenMP, run the following.
brew install cmake libomp
NOTE: lightgbm v3.3.3 and older does not support the newest version of OpenMP available as of this writing (v15.x). That was fixed in microsoft/LightGBM#5563. If you end up with OpenMP >=15.0 and lightgbm>=4.0 is not yet available from PyPI, either downgrade OpenMP or build a development version of lightgbm (see "Install from GitHub" in the docs).

Cannot install Flask in PyCharm on MacBook

I am quite new to Python, so maybe this is something quite dumb. I tried to install the Flask module in PyCharm, first in the preference window, later in the python console (but the built in).
I am on a MacBook with the newest OS, using Python 3.9. The error message in the python console is the following:

(venv)
(I censored the path in this code block, everything else is original)
With googling I found different solutions, like downgrading setuptools to 21.2.1 for example, installing python wheel. I did not find MarkupSafe Wheels.
But nothing helped, even trying to install flask by easy_install was unsuccessful.
Maybe someone encountered the same problem and can help me or has any idea?

"Downgrading" to Python 3.8 solved this problem as flask does not support Python 3.9. Thanks for helping # sahasrara62 and # A DUBEY!

What's malfunctioning here and how to fix it?
Installing cryptography seems like a relatively straightforward thing to do with a virtual environment, but it's not working and I don't see any references to problems like this one anywhere online.
Update: the operating system type is Linux, and installation of cryptography works fine on the system itself. This problem only appears when attempting to install into a virtual environment.

for me using virtualenv solved the problem
create virtual environment by
python3 -m virtualenv venv
then install cryptography
pip install cryptography

Storing complete log in C:\Users\hp\pip\pip.log
According to this link I'm supposed to install python-dev, python-psycopg2, libpq-dev before installing django-toolbelt.
I'm on a Windows machine. How can I install these dependencies? I tried installing them with pip but that doesn't work.

Apparently psycopg2 installers do not work under a virtualenv environment. I downloaded an executable binary from http://stickpeople.com/projects/python/win-psycopg/
To install the native binary in a virtual envrionment, use easy_install:
C:\virtualenv\Scripts\> activate.bat
(virtualenv) C:\virtualenv\Scripts\> easy_install psycopg2-2.5.win32-py2.7-pg9.2.4-release.exe

This blog post seems useful for your case:
http://www.swarley.me.uk/blog/2014/02/24/create-a-django-development-environment-on-64-bit-windows-for-heroku-deployment/
Or you can just find the windows ports for these dependency packages.

pyOpenSSL on Windows 7 Crypto error

Ok, I've attempted to make pyopenssl work on my windows 7 x64 instance and can't be very much luck.
I want to use pyopenSSL and I've installed like this pip install pyopenSSL.
Matter is I can't make it run, Installed python 2.7 added to register, make pywin32 for it, but can't work. I have all necessary config in PATH and scripts, but doesn't work at all.
When I tried here's the log I get.
What am I missing here? I'm blind. Thanks in advance for any help.

You can download pyOpenSsl built msi here!
If u use 64bit windows, u can just download 32bit built package, and when install, choose the python location manually.
good luck.
