I am still trying to install Flask on the 'virtual enviroments'. I had some errors trying to get the pip commands when virtualenv activated. (had something to do that my username has a space in the name)
But finally found a solutions, just type the right path to where pip is located, to avoid the username folder.
(venv) C:\Users\Daniel P-C>cd C:\Python34\Scripts
(venv) C:\Python34\Scripts>pip
Usage:
pip <command> [options]
etc...
well when trying to install flask I get the following errors
(venv) C:\Python34\Scripts>pip install flask

Be sure, you use pip and python from venv
For a module/package to be installed by pip into virtualenv, you must use the pip from virtualenv.
For importing modules/packages being installed into virtualenv environment you have to run python interpreter from given virtualenv.
In case, you run your pip or python from directory C:\Python 34\Scripts, it is very likely, you use system wide pip and install flask into system Python. On Linux you would get problems as installing into system wide python requires root privileges, on MS Windows default Python installation it does not complain.
Advice: Create your virtualenv out of default Python installation directory and use pip and python from this virtulaenv. This is what usually happens, when you activate the virtualenv, so there is no need to explicitly using full path to pip or python (anyway, using explicit path to venv python and pip would not harm anything.
I had exactly the same problem as you, and the answer of Jan didn't work for me.
The problem was simply that I installed virtualenv using apt-get:
$ sudo apt-get install virtualenv
Instead of installing it with pip:
$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ sudo python get-pip.py
$ sudo pip install virtualenv
It solved the problem for me. You can even uninstall the apt-get package after:
$ sudo apt-get remove virtualenv
virtualenv is still installed (but the good one!).
Did you add python to your path?
Try this:
Click Start
Search Advanced Systems setting and click
Click on Environmental Variables.
Append ;C:\python27 to the Path variable
Restart the Command Prompt.

=============================DEBUG ASSISTANCE=============================
If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation.html for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq.html
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation.html#rust
5) If you are experiencing issues with Rust for *this release only* you may
set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

Try installing wheel first. mostly the error describes itself. try going through them carefully, it will save you lot of debugging time.
Run this command:
pip install wheel
Let me know if the error still exists.
Install the wheel package first. While you're at it, upgrade the whole pip "stack":
python -m pip install -U wheel setuptools pip
I have a new Debian VPS, and a Django project that I am trying to deploy is not seeing django.contrib.staticfiles.*. Doing a "pip install django-staticfiles" has not observably changed things.
What is the best way to have things running well enough that such Django projects will run?
--EDIT--
I tried to uninstall Django and then install with pip and a virtualenv. This resulted in another error, failing to import execute_manager. The terminal output was:

Below is an example instance of it messing up. This was my reference: http://flask.pocoo.org/docs/quickstart/

As the error said - you have a non-ASCII character in your hello.py code but you haven't declared an encoding. You can fix this by adding a comment to your source code in the first or second line declaring the encoding. For example, if your file is saved in UTF-8:
# coding: utf-8
See PEP 0263 for more details.
