I want to run this Github code on my MacOS: https://github.com/llSourcell/AI_Startup_Prototype/tree/master/flaskSaaS-master

I have both the latest pip, Python 2.7 and 3.7

I have also installed Flask (for python 3: https://dev.to/sahilrajput/install-flask-and-create-your-first-web-application-2dba )

and made a hello world in PyCharm

I use the given setup instructions from the Github project: I go to the folder (I have downloaded it and extracted the zip) than I run the 1st set up code on the terminal:

make install && make dev

And I get the following message:

pip install -r requirements.txt
Collecting Flask==0.10.1 (from -r requirements.txt (line 1))
  Could not fetch URL https://pypi.python.org/simple/flask/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
  Could not find a version that satisfies the requirement Flask==0.10.1 (from -r requirements.txt (line 1)) (from versions: )
No matching distribution found for Flask==0.10.1 (from -r requirements.txt (line 1))
make: *** [install] Error 1

Thank you for the help

Seems like an issue with the certificate verification. You can try to working around it by adding pypi.org (the registry) and files.pythonhosted.org (the file storage) as trusted hosts.

Try this:

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org Flask==0.10.1

The issue may also be fixed by re-installing pip

  • You need to add `pypi.python.org` as a trusted host too I guess. Did you try upgrading pip? – rdas May 11 '19 at 12:52
  • reinstalled pip than run your code than it works :D – Peta May 11 '19 at 13:00
