Python, can not install pyaudio

I'm trying to install pyaudio in 3 ways but failed:
Solution 1
pip install pyaudio
of course, it's not working but worth a try.
Solution 2
pip install pipwin
pipwin install pyaudio
and this is what I got:

Solution 3
pip install PyAudio-0.2.11-cp36-cp36m-win_amd64.whl
and the result:
WARNING: Requirement 'PyAudio-0.2.11-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
ERROR: PyAudio-0.2.11-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.
I even go to this page directly and got “ERR_CONNECTION_TIMED_OUT” error when clicking on the file.
I just wonder if there is any problem with the main page? Or it's because of my system? And any way to install pyaudio?
(I'm currently on win10 64bit)

Looking at the pypi files page for PyAudio, the latest wheels are for Python 3.6.
From your traceback it seems like you are running Python 3.7, so that won't work. The link on the pythonlibs page also times out for me.
If pip cannot find a suitable wheel, it will try to compile the package using its setup.py.
Nothing for it but to set up a development environment and compile it yourself. This link might help with that.

Python 3 virtual environment uses default Python's (2.6) socket connections for PyMySQL

A server's default Python version is 2.6. Python 3 is also installed and I created a virtual environment (python3 -m venv py3env) and installed Flask and PyMySQL within the virtual environment.
However, after the web-server (Apache+WSGI) is configured, the application doesn't work and throws the following error:
File "/var/www/webapp/py3env/lib/python3.6/site-packages/pymysql/__init__.py", line 90, in Connect

return self._sock.recv_into(b)
TypeError: recv_into() argument 1 must be pinned buffer, not bytearray
I tried installing python-socketio via pip but it still isn't being used.
MySQL-python is installed on the server.
How does one force the application to use the Virtual environment's version?

AttributeError: decoding error while running Python tweepy script in Ubuntu

I have a Python 3.5 script which essentially is a Twitter scraper that collects tweets using the tweepy package and its StreamListener function.
Now my script runs perfectly within the Command shell but when I try to run it on the Ubuntu environment of my server I receive a decoding error.
File "/usr/lib/python3/dist-packages/tweepy/streaming.py", line 445, in filter

return string.decode('utf-8')
AttributeError: 'str' object has no attribute 'decode'
This makes sense because you can't decode a string which already is a string. But my question is how I can solve this issue because this is an error occuring within a package?

It looks like the problem comes from requests-oauthlib, you are running an old version of it, and the problem seems to have been fixed since 4.0.1 .
Upgrade your system (the packaged version with Ubuntu 16.10 is 7.0):
sudo apt update && apt upgrade
Or install using pip:
sudo pip3 install requests-oauthlib

Pip install from requirements file is failing, but installing one by one works

I am trying to install a bunch of python dependencies using a requirements.txt file with the following command:
pip install -r requirements.txt
The requirements.txt file has the following packages:
pep8
selenium
paramiko
soappy
nose
wmi
mock
python-keystoneclient
python-novaclient
python-cinderclient
python-swiftclient
python-glanceclient
python-heatclient
python-neutronclient
But when running the pip install command I am getting this error:

irements.txt (line 9))

Storing debug log for failure in C:\Users\cjmarti2\pip\pip.log
But for some reason if I install all packages using pip install <package> they all get installed correctly.
A couple of things to consider;
1) since I am in my company's intranet I am setting a proxy using set https_proxy=https://company-proxy.com:port. 2) Installing the exact same packages using requirements.txt in a Linux machine works fine. Any ideas?
Update:
I was using Python 2.7 for 64 bits. I uninstalled it and installed the 32 bits, and I no longer had this problem. Looks like the python version was the problem, the 64 bits one for some reason cause problems.

pip install django timeout on MacOSX Lion

On a MBP, following instructions (http://techblog.rosedu.org/python-environment.html), I installed Xcode 4.4.1, brew (brew doctor says all set), and then python. Next, I tried to setup virtualenv:
> $MYPYTHON/bin/python distribute_setup.py
> $MYPYTHON/bin/easy_install pip
> $MYPYTHON/bin/pip install virtualenv
I then created a virtual environment and tried to install django:
> $MYPYTHON/bin/virtualenv $MYENV
> $MYENV/bin/pip install Django
It downloads 98% and then hangs for a while, and finally I get a traceback indicating a timeout:
pcm#pcm-mac[302]% $MYENV/bin/pip install django

I see the same thing, if I just run the version of pip from /usr/local/bin/. I tried other packages (selenium, mock) and they downloaded and installed fine.
I'm at a loss as to what I may be doing wrong, or if there is some issue with django installs via pip. Advice?

Use:
pip --default-timeout=60 install django
