Hello! I have been trying to install pyAudio for some time now but i keep getting errors [duplicate]

so I recently upgraded to Python 3.9 and when trying to install some libraries - specifically pip install discord - I encountered the following error:
ERROR: Command errored out with exit status 1:

Obviously I went to the link and downloaded the build tools and then checked the C++ part but after restarting my computer, re-installing visual studio, I am still encountering the same problem. I am wondering if there is a part in the installation process that I am missing out on or if I have messed something up.
Any help appreciated.

Open up visual studio installer and select modify build tools
Go to individual components and make sure C++ 2019 Redistributable Update, C++ CMake tools for Windows, MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27), C++ AddressSanitizer (Experimental), C++ Build Tools core features, are checked.
If not check them and select modify. If you are on an ARM or ARM64 based system, replace MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27) with the ARM or ARM64 version.

Try to install Visual Studio: https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=16, and Visual Studio C++ Build Tools: https://visualstudio.microsoft.com/visual-cpp-build-tools/. The problem should be fixed.
Make sure you have version 14+.

I think for installing discord api you need to write the command pip install discord.py and not pip install discord

Error when trying to install eralchemy in Jupyter from a Windows device

Good day
When I run the command
pip install eralchemy
in a clear Jupyter notebook from a Windows device, I get the lengthy error message below. I have already installed Graphviz with Chocolate and Visual Studio with its BuildTools. Any help?

This should work :
pip install --upgrade --no-deps git+https://github.com/psychemedia/eralchemy.git

Bingo! It works with GoogleColab. Thank you all for your contributions.
Here are the steps I followed with your help:
I opened the notebook with Google Colab
I saved my database and csv files in the content folder in Google Colab
I ran the following command as suggested:
pip install --upgrade --no-deps
git+https://github.com/psychemedia/eralchemy.git
I imported render_er from eralchemy
from eralchemy import render_er
I drew from the database with ...
render_er("sqlite:///relative_path_to_db.db", 'erd_from_sqlite.png')
And tada! it shows an ER Diagram of my database in Google Colab.
Now the follow-up question: Now that we know how to make it work in GoogleColab, can anyone figure out how to get it to work in Jupyter?

Running setup.py clean for cryptography
Failed to build cryptography
Failed building wheel for cryptography
Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
However, when I try to install autobahn and cryptography using windows elevated command prompt(run as administrator), it installs correctly. Can anyone iterate how to install autobahn and cryptography without admin privileges and without including global-site packages in pyCharm?
P.S I have already installed MS Visual Studio build tools 2019 and openssl_X64.

Microsoft Azure Django Python setup error Pillow

All sorta new to using Microsoft Azure and needed help deploying a Django App to it. When I push the code from my local repo to Azure it gives me this log.
I noticed it says :
The headers or library files could not be found for zlib, a required
dependency when compiling Pillow from source. Please see the install
instructions at
https://pillow.readthedocs.io/en/latest/installation.html
I did more reading and learnt that Azure cannot install PIL or Pillow from the environment and hence needs to be installed on my system and then uploaded to Azure. I included a file called ".skipPythonDeployment" so that it doesn't erase the environment set on my local system, but then the deployment would fail again.
The important part of the Log generated while Pushing the code to Azure is attached below.
Detected requirements.txt. You can skip Python specific steps with
a .skipPythonDeployment file. Detecting Python runtime from site

Thank you

It seems that you were using Azure Web Apps/App Services for deploying your Django App which contains the Pillow package, and the Pillow package seems that you declared in the requirements.txt like Pillow>=2.0.0.
However, unfortunately, there are two issues for using the Pillow package on Azure App Services.
Pillow includes C code which need to be compiled when deploying your app into Azure. The solution is that you need to build a wheel file of Pillow to add it to your project and declare the wheel file in the requirements.txt, please refer to the section Troubleshooting - Package Installation of Azure offical tutorial for Django to know it.
Pillow as an image library for Python required GDI API & resources. On Azure App Services, any GDI calls are restricted and blocked, please see here to know.
So the only way for deploying your Django App is using Azure VM.

Your pip is too old to download the whl (known issues with default version of Python). Please update your Python installation or update pip directly:

Error while installing cryptography using pip

Installation fails in Ubuntu 14.04 while I tried to install cryptography. I have tried to check if their are any special requirements from ubuntu side apart from basic python installation, I have also installed the below requirments.
"libxml2-dev",
"libxslt1-dev",
"lib32z1-dev",
"libffi-dev", #Requirement of cffi
"libssl-dev",
Below is the error which it shows.

I found the answer, this error has occurred due because of the low resources on server.
I needed more ram or a bigger swap file for the command to succeed.
Similar Issue: lxml installation error ubuntu 14.04 (internal compiler error)
What I did:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=524288
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Then pip install cryptography. Worked for me. :)
