    Building for WebGL with version 5.4.0b13 results in failure. I think it worked before, can't be sure though. The error I get is "System.NotSupportedException: Don't know how to get python path on current platform!"

    A more detailed error log as follows:

    @JKarkkainen

    Which OS are you using to run the Unity editor in this case?

    @JoshPeterson Ah, I usually remember to tell my OS. Anyhow, I'm using Linux Mint 17.3. However, I have an inkling that this is a general linux issue, and not reflective of my distribution.

    Thanks for the information. I agree, this is likely a general issue on Linux. Can you submit a bug report for this issue and let me know the bug number? This is something that we should be able to correct.

    We've found the issue with this - it should be fixed in an upcoming build.

    Cool! The WebGL bug has been a pain, so thanks for getting onto it so quickly. In fact, thanks for all the work you've done getting Unity to work on Linux. It's very much appreciated.

    It looks like you did! After updating to 5.3.5f1 (see here) on Ubuntu 15.04, I was able to make a successful WebGL export. Thank you so much for fixing this! Also my impression was that CPU usage has gone down, but is still significant.

    I'm glad you were able to correct this. Unfortunately the error message here is rather cryptic. We've improved it in Unity 5.5 though to detect this case and provide a clearer indication of how to correct the problem.

    Sorry, I don't follow. Is this the same error listed above? If so, when does it occur now?

    im coming with a strange error
    my settings on web gl are
    Webgl memory size - 256
    Enable exception - Explicitly thrown exception
    Data caching - V

    ---------------------------------------------
    IF i setup :
    Webgl memory size - 512
    Enable exception -Full
    Data caching - V
    the game will run without error but sadly with lag
    Maybe is here someone to help me with this setting because i want to join in that program Alpha testers for facebook:
    Tanks !

    Can you try a build with the memory increased to 512?

    Webgl memory size - 512
    Enable exception - Explicitly thrown exception
    Data caching - V

    This feels like something that might be a memory issue, but I'm not sure. I doubt the exception settings would have an impact. We can probably confirm that with this data point.

    Webgl memory size - 512
    Enable exception - full
    Data caching - V

    i play in map about 10 seconds then appear :
    An error occured running the Unity content on this page. See your browser's JavaScript console for more info. The error was:
    NS_ERROR_UNEXPECTED:
    here is the link if you want to test it http://www.playbestgames.co/other/test_unity5.4a/
    now i will test it like this :
    Webgl memory size - 512
    Enable exception - full
    Data caching - V
    here is the link http://www.playbestgames.co/other/test_unity5.4b/
    also i get error on this
    At final i will remain at unity 5.3.5 is better than last update , maybe on the next update will be better

    Could you make a development build, and post the stack trace from that?
