Solvedspeech_recognition Install/compilation of PyAudio failed

Kubuntu 17.10.1
Python 3.6.3
Pip 9.0.1

Created a virtual environment and read through the SpeechRecognition instructions. Here are the steps

$ sudo apt-get install python-pyaudio python3-pyaudio

that went okay, it also installed libportaudio2

$ sudo apt-get install python3 python3-all-dev python3-pip build-essential swig git libpulse-dev

Apt also added the suggestions - "The following NEW packages will be installed:
libglib2.0-dev libglib2.0-dev-bin libpcre16-3 libpcre3-dev libpcre32-3 libpcrecpp0v5 libpulse-dev libpython3-all-dev pkg-config python3-all python3-all-dev swig swig3.0"

Then installed SpeechRecognition

$ pip install SpeechRecognition

Then tried SpeechRecognition and got an error

$ python3 -m speech_recognition

Tried installing PyAudio , even though it is already installed via Apt

This appears to be the same problem - SlapBot/stephanie-va#8 . I will try the solution at SlapBot/stephanie-va#8 (comment)

Not sure if the following had an impact or not. The apt commands I used were run within a virtual environment, but I would have thought anything to do with Kubuntu packages would be system wide. I installed SpeechRecognition with pip instead of pip3 (I don't think it matters).

Although if I run pip3 or pip within the virtual environment, they both say version 9.0.1, yet if I run them both outside the virtual environment, it shows pip3 is installed but not pip.

Tried those apt commands ( I left our libportaudio2 as apt informed me it was already installed)

$ sudo apt install libasound-dev portaudio19-dev libportaudiocpp0

which resulted in

The following NEW packages will be installed:
libasound2-dev libjack-dev libjack0 libportaudiocpp0 portaudio19-dev uuid-dev

Back to the VE, and although building the wheel fails, installed PyAudio

$ pip3 install pyaudio

Seems to fix it. The readme at https://github.com/Uberi/speech_recognition/blob/master/README.rst needs updating to reflect the additional packages required (if PyAudio is to be used)

I got the same error, and I found that the file "portaudio.h" was truly missing. So i first usebrew install portaudio and then pip install pyaudio . These work for me. If those commands still not work ,maybe this may help.
