Can't install the Google Assistant library on a Raspberry Pi 3 Model B

I have been trying to install the Google Assistant library on a Raspberry Pi 3 Model B running Raspbian Stretch with Desktop September 2017 by following the guide, Download the Library and Run the Sample.
I created a Python virtual environment successfully. However, I couldn't install the library. A log is as follows:
$ python -m pip install --upgrade google-assistant-library
Collecting google-assistant-library

Cannot use Google Native Client SDK on Windows 7

I am trying Google's Native Client SDK.
OS is Windows 7, I've already installed python 2.7.9 and setup the environment variable path accordingly.
I also downloaded nacl_sdk.zip from https://developer.chrome.com/native-client/sdk/download and extracted it.
However, as I run the command "naclsdk list" as it is described on the download page, I got the following messages:

In fact, no matter what command I use, it doesn't seem to work at all.
Does anyone know the solution?

having the same issue.

GAE SDK 1.8.3 Python: InvalidCertificateException on deploy

I keep getting the below error every time I do a deploy after updating GAE to a new version (1.8.3 in this case).
I have read other questions about this and the going recommendation is to delete /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/*cacerts.txt
Does anyone know of a better fix than deleting these files after every update?
Note: I have the Python SSL module installed

Socket timeout when using Buildout

We're using Buildout as a way to build our packages here, and we're consistently getting really frustrating timeouts when trying to download eggs by running bin/buildout:

Is there a way to prevent these timeouts? why do they happen?

The index server failed to respond, the connection timed out. This happens when PyPI is down, for example. By default, the index server is http://pypi.python.org/simple, but you can set your own with the [buildout] option index.
We use an egg proxy (set up with collective.eggproxy) to create a local cache automatically, to avoid such problems. Our buildouts use that server as the index, and the proxy will download any missing packages from PyPI and cache them locally. So, for any packages that we have used in the past, we can continue to serve even when PyPI is (temporarily) down.

I tried to figure out why this happens, especially that it didn't happen to me before.
Anything that I've done about it just didn't work. What's weird is that if I keep trying, then after about 20-30 attemps - it just magically deploys..
In my opinion there might be some Wifi problems. For example when I start xChat - it can't connect to server. I think that this problems might be connected.
Nevertheless I can't figure out anything, so I would be thankful for any help.
