I tried to help('modules') and there was no nose module.
I even tried pip install nose, sudo pip install nose, and etc..
When ever I tried to install nose with command line, it will throw out
SyntaxError: invalid syntax.

What should I do?
I think your pip3 and python3 versions are mismatched, possibly due to multiple versions of Python 3 installed.
Run pip3 --version to find the exact Python version that pip3 is associated with and the location of site-packages directory.
Then, run python3 and look at the location of site-packages using:
import site
site.getsitepackages()
If you see different directory locations then that's your problem - multiple versions of Python 3. If it is indeed the problem, remove both the versions, re-install the correct one and then install your packages.
I hope this helps!

I downgraded Pip from the most recent version using sudo python -m pip install pip==18.0 --upgrade, and now I am receiving the following error when running pip/pip3, including when trying to re-upgrade it using pip3 install --upgrade pip

Not sure if there's a specific reason you installed pip 18.0 as it looks incompatible with Python 3.10. It looks like in Python 3.10 collections.Mapping moved to collections.abc.Mapping. I would suggest just completely uninstalling pip and reinstalling, without using pip to do so.
In general, you should try to use the latest version of pip.
I am trying to run a program (obviously written in python) and it requires some python modules. One of the missed modules is aiomultiprocess. I tried installing it with pip install aiomultiprocess pip3 install aiomultiprocess python3.7 -m pip install aiomultiprocess but they all come back with the same error message:

ModuleNotFoundError: No module named 'ffi'
No ffi module?! Let's get it!
I looked it up and figured it's a foreign library that come, in the case of python, as 2 forms: CFFI & LibFFI, but "ffi" doesn't exist for python. I installed cffi libffi and added them to this path /usr/local/lib/python3.7/site-packages/, but it changed nothing.
So my question is there another way to install python modules without the need of pip??!
I just did a conda install of a few packages to follow a tutorial, and now I can't even import pandas.
I installed these:
fake-factory==0.7.2
Faker==0.7.3
pytz==2016.7
tzlocal==1.3.0
And now I get this:
>>> import pandas

I tried doing a conda update pandas, but to no avail.
I also just installed luigi, not quite sure when it broke as I installed all the additional packages in one go.
Updated version of pandas package using pip3
try this in python3
pip3 install --upgrade pandas
Try updating pandas package in Anaconda:
conda install pandas=1.1.4
If no luck, try updating all packages:
conda update --all
Worked in my case.
I'm using virtualenvwrapper. Under my virtualenv with python3, I installed futures successfully, then if I install anything else, it will pop up syntax errors which comes from futures package

SyntaxError: invalid syntax
I checked the answer in this question: pip install error within Python 3 virtualenv, but it doesn't work for me. The futures package is indeed installed in the right version of python which is python 3.6.5.
I tried to install futures on python3.6 globally and everything works fine. so it seems something with the futures and the virtualenv.
Can anyone please help me solve this issue?
Thanks so much
I got this issue because there's a python3 package's requirement includes futures.
If you're short on time you can downgrade setuptools to 45.2.0 to bypass it.
futures package at PyPI is a backport of the concurrent.futures standard library module to Python 2.
To use futures in Python 3 you don't need to install anything, it's a standard library module.
Now your virtualenv contains a broken Python 2 module. I recommend to remove the virtualenv and recreate it.
I have the Anaconda distribution of Python 2.7 and I needed to install the Jupyter notebook package. During the installation process my computer turned off and after that I couldn't continue with the process. I tried to uninstall Jupyter and try installing it again, but I keep getting the same error:

What should I remove/add in order to make it work?
You need to install the python package simplegeneric. After you install it, you need to install the next package that you fail to import. Continue this process until you dont get any import errors.
