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
errors are as follows:
$ pip install futures
Collecting futures
Installing collected packages: futures
Successfully installed futures-3.1.1
$ pip install sklearn

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 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

from collections import Mapping
ImportError: cannot import name 'Mapping' from 'collections' (/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/collections/__init__.py)
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:

import ffi
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 have been trying to get pip with python3 on WSL ubuntu 16.04 and have had no success. I have been running sudo apt install --reinstall python3-pip, but still have issues getting pip to work properly.
$ pip3

from distutils import sysconfig
ImportError: No module named 'distutils'
Also I noticed that I seem to have two versions of python3 installed:
$ ls /usr/lib | grep python
python2.7
python3
python3.5
According to Python 3 documentation, distutils apparently is not deprecated, BUT, my install of 2.7 has disutils, but 3.6 does not.
When I read:
https://docs.python.org/3/installing/
It seemed to say that distutils was being deprecated, but it was not worded clearly if they were talking about distutils or something else.
If anyone knows the definitive answer, please let us know.
So after a lot of pain, I finally gave in. I had made things worse and corrupted my entire python3 installation. I had corrupted too many files trying to fix everything. I ended up uninstalling WSL/ubuntu and reinstalling clean. I made of backup a few things first.
Unfortunately, this seems to be the best option if you have really messed this up, like I did. Being more careful now, python3 is working just fine, with pip. Make sure you follow official docs when you install.
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.
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

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!
