<p dir="auto">Are there any plans to add type stubs for PEP484-compliant static typing?</p>
<p dir="auto">I am trying to set up a flask application on my new machine. First I checked out the sources from our server - I am pretty sure the application directory structure is correct, as we are using it exactly like this on other machines.</p>
<p dir="auto">However, when I try to run the app on my new computer I get the following error:</p>

<p dir="auto">Problem is: No more output is printed, in particular no stack trace. So I don't know what exactly the problem is. How can I tell flask to print the stack trace?</p>
