I am using python 3.9 and I can't figure out how to install pyaudio in my Windows 10

Currently using Visual Studio Code
Tried using pip install pyaudio but it simply gave an error like:
PS C:\Users\NIKHIL> pip install pyaudio
Defaulting to user installation because normal site-packages is
not writeable

please suggest a way out of this

You can also try to install it with the .whl file.
Find your Python version
64 or 32 bit?
Find the appropriate file here
For example, my Python version is the 3.9 64bit I would download the "PyAudio‑0.2.11‑cp39‑cp39‑win_amd64.whl" file.
Open your CMD and go to the folder where the file is. Ex.: cd C:\Users\Miguel\Downloads
Install it: pip install PyAudio‑0.2.11‑cp39‑cp39‑win_amd64.whl
Hope it helped!

This answer from a StackOverflow question might help, as I had the same problem and it solved the problem for me.
First run your IDE or CMD as Administrator and run the following:
pip install pipwin
pipwin install pyaudio

Try these commands below:
pip install pipwin
pipwin install pyaudio

Looking at the error message it seems you require Visual C++ build tools.
The link to download that is also given within that error message.
In case the link does not work,You can download it here: https://visualstudio.microsoft.com/visual-cpp-build-tools/
You can try this and incase errors still persist, reply to this thread.
Upvote if it helped!

PyAudio just doesn't have the wheels for Python 3.7 or higher. If you want to use PyAudio, it is best to download python version 3.6.9 here.
I wish you the best
-arivvid27

I tried with Python 3.9 and didn´t work, so I installed Python 3.8 too and pyaudio worked fine (I've double checked and downloaded both versions of pyaudio on https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio).
I still don't know why it doesn't work on 3.9.
Did it work for someone on python 3.9? If yes, let me know what did you do. Thanks!

you should use python 3.6.9 or lower

Can't install mmh3 for Python3.7.1 on Win10x64 - visual C++ build tools aren't recognized

I'm trying to install mmh3 (with some other libs) on Python - other libs are installing OK, but mmh3 rises an error:
ERROR: Complete output from command 'c:\python37\python.exe' -u -c 'import setuptools, tokenize;__file__='"'"'C:\\Users\\evgeniy\\AppData\\Local\\Temp\\pip-install-ppmbqvid\\mmh3\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record 'C:\Users\evgeniy\AppData\Local\Temp\pip-record-6no3ekq2\install-record.txt' --single-version-externally-managed --compile:

After i got this error at first, i've installed Microsoft Visual C++ Build Tools 15 (v14 was installed too), checked, whether Python has its environment variables and restarted.
After restart and running pip install -r requirements.txt same error fires again. AND, really weird: the paths cited in the error text don't exist, both of them:
not C:\Users\evgeniy\AppData\Local\Temp\pip-record-6no3ekq2\install-record.txt
not C:\Users\evgeniy\AppData\Local\Temp\pip-install-ppmbqvid\mmh3\
In the folder named TEMP, which obviously exists, are no leftovers of mmh3 install or logs or anything related.
What should i do to get mmh3 installed?
PS:
solution under https://www.scivision.dev/python-windows-visual-c-14-required/ doesn't help
installing Python into default installation directory (AppData/Local/Programs/Python/Python37) doesn't help too

The trick is to install the lib (mmh3 or any other, which makes troubles) from within Visual Studio.
From within means from its own terminal / cmd window, like explained in the step 4 of Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)

Problem installing weka package to python3

I have a problem with install weka by pip install python-weka-wrapper3. (The solution here did not work with me).
This error appears when I am trying to run the command above:
Command "c:\users\nujou\appdata\local\programs\python\python36\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\Nujou\\AppData\\Local\\Temp\\pip-build-ctvavwi1\\javabridge\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Users\Nujou\AppData\Local\Temp\pip-cdmf95_m-record\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\Nujou\AppData\Local\Temp\pip-build-ctvavwi1\javabridge\
EDIT:
the problem was:
"error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": visualstudio.microsoft.com/downloads"
therefore, it is solved by downloading Microsoft Visual C++ Build Tools.

I cannot find anything regarding this error. Please suggest me what should I do?

The error you are receiving is: error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools. You need to read the error message carefully.
You just need to go to the link they have provided for you and follow the instructions: http://landinghub.visualstudio.com/visual-cpp-build-tools

Following below steps helped me overcome the error:
While installing the Visual Studio: Download Visual Studio
-> Desktop development with C++
-> Check C++/CLI support for v142 build tools (14.24)
Having the below dependency ready:
get Python --Version in CLI.
Download and install whl file from Twisted WHL file
pip install C:\"Twisted‑19.10.0‑cp36‑cp36m‑win_amd64.whl"
Finally Run:
pip install -v pyemd

how to overcome this isuue?

As you can see from the error log, the problem here is that on your machine is missing Microsoft Visual C++ 14.0.
To fix this problem, simply install it, follow the link that you find in the traceback (this one), and try again with the command
pip install tesserocr

Reload Python directly with Anaconda, and use:
conda install -c simonflueckiger tesserocr
