Ursina.build can't find modules?

I was reading This, when it said I was supposed to use the command python -m ursina.build to compile my project. When I launched the .bat file I got this error
package_folder: C:\Users\sbahr\OneDrive\Documents\programming\Python\MeshGame\build\python\lib\site-packages\ursina
asset_folder: src
screen resolution: (1920, 1080)
Traceback (most recent call last):

import numpy as np
ModuleNotFoundError: No module named 'numpy'
I ran pip install numpy and it said numpy was already installed.

This used to be automatic, but broke in a newer version of Python. Therefore you'll have to provide a list of extra modules to copy, if you're using any.
From ursina's documentation (https://www.ursinaengine.org/building.html):
Make sure to include any extra modules with --include_modules PIL,numpy for example.

Unable to import psutil in Python 3.7 (Import Error)

I am unable to import psutil when I activated python on my venv, its gives the following error message, which I cant resolve.
I tried to uninstall psutil and install psutil again but it still returns the same error.
>>> import psutil
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Will appreciate if anyone knows how to resolve this issue, thanks.

Does it raise the same error when you activate the venv, open the virtualenv python interpreter and import psutil?
Another cause I can think of is when you name your script psutil.py and within that script you try to import the psutil module.
(see the post of Yong Wang: airflow error:AttributeError: module 'airflow.utils.log' has no attribute 'file_processor_handler')

Why i got that problems when i run my script?

Hi, is there a solution for this error code ?

Thanks.

The answer is pretty self explainatory and with a google search you could have solved everything in seconds.
Here you have a how to install pip if you don`t have it: How do I install pip on macOS or OS X?
After this type in the terminal:
pip install Mako
as stated in the official website: http://www.makotemplates.org/download.html
If this doesn`t work you can manually download the Mako package here:
https://pypi.python.org/pypi/Mako/

Python igraph import error on Windows

I've installed igraph form .whl file using pip install. When I was trying to test the correctness of installation
import igraph.test
igraph.test.test()
I got this error:
Traceback (most recent call last):
File "D:/Nauka/Praca-inzynierska/Barabasi-Albert.py", line 4, in <module>
import igraph.test
File "D:\Programy\Python 3.5\lib\site-packages\igraph\__init__.py", line 34, in <module>
from igraph._igraph import *
ImportError: No module named 'igraph._igraph'
(the same error pops out if I'm trying to import igraph not igraph.test).
I've tried adding path (I don't know if this is rigth):
import sys
sys.path.append ("D:/Programy/Python 3.5/Lib/site-packages/igraph")
but it didn't work.
One thing I discovered is that if I delete "__init__" file from igraph folder I can import igraph without error, but it doesn't work for igraph.test.
If it's relevant I have Python 2.7 installed on my machine alongside Python 3.5.
Thank you in advance for any help.

How to install mathplotlib - python

I'm using sublime text 2 to run python 2.7. I have downloaded and installed mathplotlib. When I type the code:
import matplotlib.pyplot
I'm getting this error.
Traceback (most recent call last):
File "/Volumes/HP v190b/Python - Squash Coursework/squashFINAL.py", line 212, in <module>
import matplot.pyplot as plt
ImportError: No module named matplot.pyplot
Any ideas why? I'm using a Mac!

You may check the dependencies, sometimes you need to install some dependencies so that you can import certain module, take a look at this link http://matplotlib.org/users/installing.html
