Failed to download Python. The following exception was raised:

there is no markup readme documenting how to use the installer with a corporate proxy and no documented command line options to specify the proxy user, password server and port.

https://docs.aws.amazon.com/de_de/cli/latest/userguide/cli-configure-proxy.html documents how to set up a proxy but not how to tell it to trust the proxy's SSL certificate. The "2. Installing virtualenv" step will just fail with Could not fetch URL https://pypi.python.org/simple/virtualenv/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /simple/virtualenv/ (Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)'),)) - skipping

If the script would create a %APPDATA%\pip\pip.ini with

[global]
  trusted-host = pypi.python.org
                 pypi.org
                 files.pythonhosted.org

it would be able to have pip download virtualenv after downloading python. Since it does install an old version of pip, it wouldn't hurt to do python -m pip install --upgrade pip in the process.

Thanks for reporting your issue and the tip.

I agree. Thanks.
