web2py_osx on Sierra (OSX 10.12)

[Scott Hunter]

When I download & run a fresh copy of the web2py_osx app, I get the usual warnings about it not being from a known source (b/c it is unsigned, I presume).  In previous versions, when I told the Security System Preference panel to open it anyway, it did, and all was well.  But now, soon after it launches, I get an all-but-useless error alert "web2py error" with the choices of Show Console (which reveals nothing to my eye) or Terminate.

This is happening on 2 separate machines running Sierra.

I'm at a loss as to what, if anything, I can do about it.

Am I to interpret from the deafening silence that I am the only one seeing this problem?  Even if that is the case, any ideas how I can resolve it, or where I might go to find any?

I'm using Web2py 2.14.6 in sierra and cannot reproduce your errors.

Can you show the errors or warnings?

Sure, but there's not much to see.

When I launch the app (after Safari, presumably, has unzipped it), I get:

I click Open, and (after a little wait) am presented with:

If there is something relevant in the Console, it isn't obvious to me.

I would recommend you download Anaconda python 2.7 and run python from source

http://web2py.com/examples/static/web2py_src.zip

If it also fails, it may give more info.

I downloaded a fresh copy of the source version, ran it using the default python in OS X, and all ran fine.

I installed Anaconda python 2.7, ran the source version using it, and all ran fine.

However, I was able to run the OS X version by executing the Content/MacOS/web2py executable inside of web2py.app via the command line.

Then I tried executing that same OS X version by double-clicking the app; it presented me with a different dialog: that it was from an unknown developer, and would not open it.  But I could open it from the Security panel of System Preferences, and it worked fine.

I next tried to download the same .zip file from a different server (as my ultimate goal is to distribute my appliance via such an executable).  That exhibited the problematic behavior that I have reported previously.

Lastly, I re-downloaded the zipped-app from the web2py site; opening that (via double-clicking) is now experiencing the behavior previously reported.  But I *can* open it via the command line as described above.  And after doing so, it will open via double-click.

So the "source" of the problem seems to have been trying to download from a different server.  WHY that would cause a problem, I haven't a clue.  But I could get around it by adding a script to open the execrable directly.

I've also run into this. I'm on macOS 10.12.1

I downloaded the web2py app from http://www.web2py.com/examples/static/web2py_osx.zip

When I try to run it, I get the same web2py error dialog: http://take.ms/IIXG5

Here are the details from the console: http://take.ms/tTTgG

"Detected missing constraints for <private>.  It cannot be placed because there are not enough constraints to fully define the size and origin. Add the missing constraints, or set translatesAutoresizingMaskIntoConstraints=YES and constraints will be generated for you. If this view is laid out manually on macOS 10.12 and later, you may choose to not call [super layout] from your override. Set a breakpoint on DETECTED_MISSING_CONSTRAINTS to debug. This error will only be logged once."

Thanks for reporting this. Do you mind opening a ticket?

[ba...@seas.upenn.edu]

Could you please give the Terminal command for this? Sorry, unclear to me since I only used the GUI in the past. Thank you.

I see this happening too.  After allowing the app to run,  web2py stops working and the console errors look like this.  Is sqlite the problem?
