IB API not installing properly on Mac

So I'm trying to use the IB API wrapper from here and I try running the first line
from ib_insync import *
but am getting the following error:
Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/ib_insync/__init__.py", line 10, in <module>
import ibapi
ModuleNotFoundError: No module named 'ibapi'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.7/site-packages/ib_insync/__init__.py", line 13, in <module>
'IB API from http://interactivebrokers.github.io is required')
RuntimeError: IB API from http://interactivebrokers.github.io is required
but I've downloaded the IB API from the IB github (had to use The Unarchiver to unzip) and saved it on my desktop. As far as I can tell there's no pip3 command I can use to install it so I'm not sure what else I can do to install the IB API. I've allowed ticked all the boxes for the API in TWS. I'm not sure why it's not installing properly?
It seems to be the same issue found here but mine is for macosx. I've tried running the commands from README.md and they don't work. It just says no such directory exists.

Installing the a python module as a wheel is optional- its also possible to just include the path to the module in the PYTHONPATH environment variable. But if you're using the commands from the READ.ME to build and install a wheel, make sure you're in the pythonclient folder and then run:
python3 setup.py bdist_wheel
python3 -m pip install --user --upgrade dist/ibapi-9.75.1-py3-none-any.whl
Thats for the current API Latest version as of March 2019 which is 975.1

Heroku Moduke Not Found Error

[![][1]][1]
the module 'pyicloud' is listed in requirements.txt
I have checked using the 'ls' command- I checked the directory in which the package should be - and the package does exist on the heroku server.
The app gives no such issues on my local machine, even though there is no difference in the code
I also tried the suggestions given here : https://help.heroku.com/BWJ7QYTF/why-am-i-seeing-importerror-no-module-named-site-when-deploying-a-python-app
but it didnt work.

Naoqi python SDK error in raspberry pi during installation

import naoqi
Traceback (most recent call last):
File "", line 1, in
File "/home/pi/Downloads/pynaoqi-python2.7-2.1.4.13-linux32/naoqi.py", line 7, in
import qi

from _qi import Application as _Application
ImportError: /home/pi/Downloads/pynaoqi-python2.7-2.1.4.13-linux32/_qi.so: cannot open shared object file: No such file or directory
I tried all the things below
export DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:/home/pi/Downloads/pynaoqi-python2.7-2.1.4.13-linux32/
export PYTHONPATH=${PYTHONPATH}:/home/pi/Downloads/pynaoqi-python2.7-2.1.4.13-linux32/
sudo ldconfig -v too
nothing works

the problem because pynaoqi was build for x64/x86 architechture; Raspi's processor is ARM architechture. So it can not work on rasp.

Qt Creator failed to start Debugger

Qt c++ project build under Qt Creator 3.4.1 successfully. But when I just can't launch the debugger. Output in the application Output:
Debuging starts
Debuging has failed

The debugger never really starts.
output in the terminal :

More information:
gcc used by qt creator : version 5.0.1
gdb used by qt creator : version 7.9
python 2.6.6 installed on my CentOS 6.5 ,and is in PATH .
when I install gdb wiht source code I did not append --with-python option. I googled out that someone did build with that option but nothing happens.

The outputs in terminal exposed two issues:
the ImportError: No module named importlib leads to unsupported library in Python. So install new version of Python (greater than 2.7) as #Amartel said.But the in my situation the gdb needs to be rebuild with --with-python configuration option to make gdb use newer version of Python.
Python Exception <type 'exceptions.ImportError'> No module named gdb:
/usr/local/bin/gdb' can been solved by copy files in the directory: gdb_src_dir/gdb/data-directory/python/gdb to /usr/local/share/gdb. NOTE: my gdb is installed under/usr/local/bin.
Finally, the debugger works all fine.
However, I did not get the reason for issues 2. Any one can explain that?

Cannot find tweepy module after installing it on Windows

I installed tweepy by first cloning it:
git clone git://github.com/tweepy/tweepy.git
Copying tweepy-2.2-py2.7.egg into C:\Python27\Lib\site-packages.
Then installing it from the tweepy directory with:
python setup.py install
The final line of the installation process states:
Installed c:\users\linus\appdata\local\enthought\canopy32\user\lib\site-packages\tweepy-2.2-py2.7.egg
Processing dependencies for tweepy==2.2
Finished processing dependencies for tweepy==2.2
However, I still receive the error:
