Mac gcloud install ImportError: No module named __future__

When installing gcloud for mac I get this error when I run the install.sh command according to docs here:
Traceback (most recent call last):
File "/path_to_unzipped_file/google-cloud-sdk/bin/bootstrapping/install.py", line 8, in <module>
from __future__ import absolute_import
I poked through and echoed out some stuff in the install shell script. It is setting the environment variables correctly (pointing to my default python installation, pointing to the correct location of the gcloud SDK).
If I just enter the python interpreter (using the same default python that the install script points to when running install.py) I can import the module just fine:
>>> from __future__ import absolute_import
>>>
Only other information worth noting is my default python setup is a virtual environment that I create from python 2.7.15 installed through brew. The virtual environment python bin is first in my PATH so python and python2 and python2.7 all invoke the correct binary. I've had no other issues installing packages on this setup so far.
If I echo the final line of the install.sh script that calls the install.py script it shows /path_to_virtualenv/bin/python -S /path_to_unzipped_file/google-cloud-sdk/bin/bootstrapping/install.py which is the correct python. Or am I missing something?

The script uses the -S command-line switch, which disables loading the site module on start-up.
However, it is a custom dedicated site module installed in a virtualenv that makes a virtualenv work. As such, the -S switch and virtualenvs are incompatible, with -S set fundamental imports such as from __future__ break down entirely.
You can either remove the -S switch from the install.bat command or use a wrapper script to strip it from the command line as you call your real virtualenv Python.

I had the error below when trying to run gcloud commands.
File "/usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/lib/gcloud.py", line 20, in <module>
from __future__ import absolute_import
ImportError: No module named __future__
If you have your virtualenv sourced automatically you can specify the environment variable CLOUDSDK_PYTHON i.e. set -x CLOUDSDK_PYTHON /usr/bin/python to not use the virtualenv python.

In google-cloud-sdk/install.sh go to last line, remove variable $CLOUDSDK_PYTHON_ARGS as below.
"$CLOUDSDK_PYTHON" $CLOUDSDK_PYTHON_ARGS "${CLOUDSDK_ROOT_DIR}/bin/bootstrapping/install.py" "$#"
"$CLOUDSDK_PYTHON" "${CLOUDSDK_ROOT_DIR}/bin/bootstrapping/install.py" "$#"

Import python package after installing it with setup.py, without restarting?

I have a package that I would like to automatically install and use from within my own Python script.
Right now I have this:
>>> # ... code for downloading and un-targzing
>>> from subprocess import call
>>> call(['python', 'setup.py', 'install'])
>>> from <package> import <name>
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named <package>
Then I can continue like this:
>>> exit()
$ python
>>> from <package> import <name>
And it works just fine. For some reason, Python is able to pick up the package just fine if I restart after running the setup.py file, but not if I don't. How can I make it work without having the restart step in the middle?
(Also, is there a superior alternative to using subprocess.call() to run setup.py within a python script? Seems silly to spawn a whole new Python interpreter from within one, but I don't know how else to pass that install argument.)

Depending on your Python version, you want to look into imp or importlib.
e.g. for Python 3, you can do:
from importlib.machinery import SourceFileLoader
directory_name = # os.path to module
# where __init__.py is the module entry point
s = SourceFileloader(directory_name, __init__.py).load_module()
or, if you're feeling brave that your Python path knows about the directory:
map(__import__, 'new_package_name')

Hope this helps,
I downloaded from seaborn from GitHub.
Through command prompt, cd to downloads\seaborn folder
python install setup.py
Then using spyder from anaconda, checked if it was installed by running the following in a console
import pip
sorted(["%s==%s" % (i.key, i.version)
for i in pip.get_installed_distributions()])
Seeing that it was not there, go to tools and select "Update module names list"
Again trying the previous code in a python console, the lib was still not showing.
Restarting Spyder and trying import seaborn worked.
Hope this helps.

Basic Flask Issue w/ Importing

I'm following a Flask tutorial and am getting an import error. I have a file called run.py which contains:
from app import app
app.run(debug = True)
When I run ./run.py, I get:
Traceback (most recent call last):
File "./run.py", line 2, in <module>
from app import app
File "/Users/myName/Desktop/SquashScraper/app/__init__.py", line 1, in <module>
from flask import Flask
ImportError: cannot import name Flask
This seems similar to this issue: http://stackoverflow.com/questions/26960235/python3-cannot-import-name-flask
So I attempted the checked solution by running:
virtualenv -p /usr/bin/python3 my_py3_env
Unfortunately, I get:
The executable /usr/bin/python3 (from --python=/usr/bin/python3) does not exist
Any ideas what may be happening here?
Thanks for the help,
bclayman

If you want your virtual environment to be Python 3 but don't know the installation directory, use which python3. Use that directory in your virtualenv -p [directory] my_py3_env command to set up the Python 3 virtual environment.
I sounds like your pip is installing to your Python 2.X directory. If you're okay with that, you'll need to run the app either with python2 run.py, python2.X run.py where x is your installed version, or change the symlink of python in /usr/bin/python to your installation of Python 2.
This question has some more information.
Regardless of the version of Python that you wish to use, you will need to install Flask to that version of Python. See this question for that.

Import Error in __init__.py : No Module named _vlfeat in PyVlfeat

I am trying to run this python rewrite of Vlfeat library.
https://github.com/shackenberg/phow_caltech101.py. I am trying to run the application phow_caltech101.
This is throwing
File "/A/B/C/pyvlfeat-0.1.1a3/vlfeat/__init__.py", line 1, in <module>
import _vlfeat
ImportError: No module named _vlfeat
In the corresponding "init.py" file, I can see it is mentioned as "import _vlfeat". I am new to python, please let me know what is causing this error?

You need to download and install PyVlfeat module.
https://pypi.python.org/pypi/pyvlfeat/
As I see, pyvlfeat has some dependencies, so be sure to download these too:
Boost.Python (tested against version 1.35.0-5)
NumPy (tested against version 1.5.1)
Matplotlib (tested against version 0.99.3)

Import error in twilio

I am having the same problem as this thread regarding twilio-python:
twilio.rest missing from twilio python module version 2.0.8?
However I have the same problem but I have 3.3.3 installed. I still get "No module named rest" when trying to import twilio.rest.
Loading the library from stand alone python script works. So I know that pip installing the package worked.
from twilio.rest import TwilioRestClient
def main():
account = "xxxxxxxxxxxxxxxx"
token = "xxxxxxxxxxxxxxxx"
client = TwilioRestClient(account, token)
call = client.calls.create(to="+12223344",
from_="+12223344",
url="http://ironblanket.herokuapp.com/",
method="GET")
if __name__ == "__main__":
main()
but this does not work:
from twilio.rest import TwilioRestClient
def home(request):
client = TwilioRestClient(account, token)
Do you have any idea what I can try next?

I named a python file in my project twilio.py. Since that file was loaded first, then subsequent calls to load twilio would reference that file instead of the twilio library.
TLDR: just don't name your python file twilio.py

Check which versions of pip and python you are running with this command:
which -a python
which -a pip
pip needs to install to a path that your Python executable can read from. Sometimes there will be more than one version of pip like pip-2.5, pip-2.7 etc. You can find all of them by running compgen -c | grep pip. There can also be more than one version of Python, especially if you have Macports or brew or multiple versions of Python installed.
Check which version of the twilio module is installed by running this command:
$ pip freeze | grep twilio # Or pip-2.7 freeze etc.
The output should be twilio==3.3.3.
I hope that helps - please leave a comment if you have more questions.

This Worked For me : (Windows)
Python librarys are in G:\Python\Lib
(Python is installed at G:, it might be different for you)
Download Twilio from github at paste the library at >> G:\Python\Lib <<
import problem gone :)

I had the same issue and it drove me crazy. Finally I figured it out. When you get the error:
AttributeError: module 'twilio' has no attribute 'version'
Look 2 lines above and the error is telling you where it expects to find the twilio file. So I moved it from where it was to where it was asking it to be.
Installed to:
c:\users\rhuds\appdata\local\programs\python\python37-32\lib\site-packages
Moved it to:
Traceback (most recent call last):
File "", line 1, in
import twilio
File "C:\Users\rhuds\AppData\Local\Programs\Python\Python37-32\twilio.py", line 2, in
Now I can import twilio. Besides that, the only other thing I did was uninstall old versions of Python, but I don't think that really mattered.
