I searched around and haven't seen this posted elsewhere.
My Windows machine uses Python 2.7 as the default Python. I ran virtualenv to create a virtual environment that uses Python 3.4:
C:\virtualenvs>virtualenv -p C:\Python34\python.exe mypy3
and got an error:
Running virtualenv with interpreter C:\Python34\python.exe

I needed to specify the full path of virtualenv:
C:\virtualenvs>C:\python34\Scripts\virtualenv.exe -p C:\Python34\python.exe
because I was effectively calling this:
C:\virtualenvs>C:\python27\Scripts\virtualenv.exe -p C:\Python34\python.exe
since C:\python27\Scripts is in my PATH. And the collision of Python 2.7 and 3.4 was causing the issue.

I think this is a Python issue. but I'm running Python3:
python -V shows
Python 3.9.0
I have installed it with homebrew.
What can be the problem?
This is a known issue across Mac, Windows and Linux: https://issuetracker.google.com/170125513.
I'd suggest to use the recommended Python versions mentioned here (3.5 to 3.8).
Also this does not affect only to Cloud SDK but others as well (for example as mentioned here).
Thanks for your answer. Indeed, it works with the version 3.8.6 of python.
I will add some infos if it can help somebody. In order to manage python version, I have used pyenv and installed the version of python I needed.
pyenv install 3.8.6
pyenv global 3.8.6
If you want a quick fix you can add this to your bash profile and restart your terminal:
export CLOUDSDK_PYTHON=python3.8
Worked for me
I tried to install Django Framework in Ubuntu. and i am using python 3.8. but in normal instalation, Django 1.1 had been installed. and i changed the python3 alternative to python3.8 . and usuing python3 -m pip install django. and i installed Django(v 3.3) and used it. but after the changing the alternative, the Terminal doesn't open and start.
i deleted python3.6 from my ubuntu. and the problems had been started after that.
it seems some programs in linux run in python3.6 and after deleting that,
i can't fix the problems and the Terminal windows does not open. i tried other ways (changing the gnome-terminal file, changing the alternative to default v3.6 and fix the Broken distro), but they didn't help me. i can't open Terminal, and when i ran sudo apt update i recieved this Errors:
Any idea?

after a few hours, i found a way to fix the problems.
First, I made a backup of all my data(I would recommend to everyone trying this). Although it worked for me, it may fail for some reason on your machine and you don't want to lose your data.
I ran the following commands to remove the old version of python3.6 without removing all the dependencies and to directly install the default version.
sudo dpkg --remove --force-depends python3.6 python3.6-minimal libpython3.6-minimal libpython3.6-stdlib
sudo apt-get install python3.6 python3.6-minimal libpython3.6-minimal libpython3.6-stdlib
I ran sudo apt-get update and sudo apt-get upgrade before rebooting my machine.
everything became ok..
Today I installed python 3.7 from apt-get to try out the new dataclasses module. I installed it seperately because python3.6 wasn't upgradeable to 3.7.
When I type: python3.7 --version, it gives me: >>> Python 3.7.0a2 as my current version.
The problem is that I can't seem to import dataclasses.
my import statement is: from dataclasses import dataclass as instructed here
This is the error message it's giving me:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'dataclasses'

ModuleNotFoundError: No module named 'dataclasses'
I even tried installing the dataclasses module with pip3: pip3 install dataclasses. Not sure if that's necessary though.
Any suggestion on what might be the problem?
[EDIT] Just tried it with a python3.6 console and it worked fine .. weird.
As suggested by #wim python3.7 -m venv venv_dir
This command will:
Use python3.7 to run the command
The -m flag tells the interpreter to run the next argument as a script
venv is a module, and because of the -m flag it will be run as a script
Finally, the venv_dir is given to the venv module as an argument which
this module will use to create a virtual environment directory at
Once this command is run now you'll have a nice sandbox for messing around/testing the dataclasses module.
To activate this virtual environment be sure to run source venv_dir/bin/activate before you begin. This command will run the script at venv_dir/bin/activate to set up the necessary environment variables and other things for you
To deactivate, simply run deactivate after activating
I am using python 3.4. I am able to run my python script without any problem.
But While running my freezed python script , following error have appeared.
I am able to freeze my script successfully too with cx_freeze.

I had the same issues running on Ubuntu with Python 3.5. It seems that cx_freeze has problems with libraries that import other files or something like that.
Importing Queue together with requests worked for me, so:
import requests
from multiprocessing import Queue
And I don't think specifying urllib in "packages": ["urllib", "requests"] is necessary.
There are Several options based on project packages:
Method1:
Answer: I solve the problem my issue was I had file named queue.py in the same
directory
Method2:
Queue is in the multiprocessing module so:
from multiprocessing import Queue
Method3:
Updating pip from 1.5.6 to 8.1.2
`sudo python -m pip install -U pip`
Reboot system (don't know if necessary, but only after reboot new version of pip was listed)
Method4:
from six.moves.queue import Queue //I don't know how u import six package
In setup.py, options={"build_exe": {"packages": ["multiprocessing"]}} can also do the trick.
In addition to
from multiprocessing import Queue
I rolled back to the older version of cx_freeze:
pip install cx-freeze==4.3.3
Besides, the "requests" library complained on absence of "urllib3" module. I upgraded this to requests==2.13.0 and all now works.
I'm using Python 3.4 on Win10. Hope this will help.
I have python2.7 and python3.5 installed via Macports. I am trying to get neovim up and running and for this I ran
$ sudo pip2 install neovim
$ sudo pip-3.5 install neovim
Which installs the packages into different subdirs of /opt/local/Library/Frameworks/Python.framework/Versions/. Now when running Python 3.5, import neovim tries to load the 2.7 package (which fails), as I can see from the stack trace.
The full error is this:

What do I have to do in order for Python 2.7 and 3 to coexist peacefully on my system?
I recently had this problem as well, but it was not related to PYTHONPATH, which on my machine was unset. In my situation Python and pip were installed via MacPorts. Cleaning, self-updating MacPorts and then updating pip to the most recent version, and then running the following resolved the issue:
port select --set pip pip35
