Why is pip installing textract failing on Debian?

I'm trying to install the python package textract on (dockerized) Debian:
FROM python:2.7
RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get -y install libevent-dev python-dev libxml2-dev libxslt1-dev antiword unrtf poppler-utils pstotext tesseract-ocr flac ffmpeg lame libmad0 libsox-fmt-mp3 sox libjpeg-dev swig
RUN pip install textract
But it fails on the last step pip install textract. Why? How to get around this issue? Below is the error:

ERROR: Service 'baleen' failed to build: The command '/bin/sh -c pip install textract' returned a non-zero code: 1

Solution:
Add RUN apt-get -y install libpulse-dev before pip installing textract.

It has clealy shows the error.
The chardet version-<3.1.0,>=3.0.2 is needed, but you have a older version<2.3.0>.
So you need uninstall your chardet
sudo pip list | grep chardet
then uninstall old version
sudo pip uninstall chardet

How to change python gcc binding to gcc 4.8 version?

I want to install a auto-sklearn package which dependent on pyrfr.
The install command is curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install.
My Env: ubuntu 12.04, python3.5-dev(in virtualenv) with gcc 4.8 and g++ 4.8 installed.
I install gcc and g++ by:

sudo apt-get install gcc-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
Defaut gcc is set correctly:

The key problem I think is python3.5 not link to gcc-4.8(even system default python2.7 not too), but google not help much.

Finnally I find the solution.. find that x86_64-linux-gnu-gcc is a command , though it doesn't looks like a command...
It seems python on ubuntu 12 would not use /usr/bin/x86_64-linux-gnu-gcc(link to /usr/bin/gcc-4.6) instead of /usr/bin/gcc, I totally coundn't understand why them do this ...
The sulotion is simple, just
cd /usr/bin
rm x86_64-linux-gnu-gcc
ln -sf gcc-4.8 x86_64-linux-gnu-gcc
If you want change g++ and cpp, also do
rm x86_64-linux-gnu-cpp
ln -sf cpp-4.8 x86_64-linux-gnu-cpp
rm x86_64-linux-gnu-g++
ln -sf g++-4.8 x86_64-linux-gnu-g++

I have installed gcc before

You are missing a library that you need in order to install this. I believe the package you need to install is postgresql-devel.

Step 1:
for rpm linux
sudo dnf install python-devel postgresql-devel rpm-build
for deb linux
sudo apt-get install libpq-dev python-dev build-essential
Step 2:
Inside you virtualenv
pip install psycopg2

Depending on which version of Python you are running in your virtualenv, run one of the following commands:
Python 2.x:
sudo dnf install python-devel
Python 3.x:
sudo dnf install python3-devel

Try this, it works for me I am using fedora 33
pip install psycopg2-binary

Run this command worked for me
sudo dnf install python3-devel
