Hi~
I’m using Cocos Creator 2.0.5.
When I launch app in Mac OSX, above error msgbox is shown frequently.
Please help me~

#2

did you have any creator app of different version in your computer ?
did you used custom engine in the app?

#3

Thanks for your reply. When I launch Creator App of version 1.10.2, There is no response without any error msg box. May be same problem. I do not use any custom engine in current app version.^^

#4

Maybe you have wrong resources imported to the project.
you can open the app with the commandline tool,and if there are any error logs,pls let me know

#5

Excellent! You’re right. May be It seems because wrong resources make error. But I can’t catch which resource is problem. I can’t find command-line tool. Only CocosCreator app file exists.

#6

I found how to launch Creator App in command-line mode.
In terminal app, change to ‘/Applications/CocosCreator.app/Contents/MacOS’ folder and launch ‘CocosCreator’ file.
But…
Same exception message appeared like this:

I had this kind of problem before after I install the latest version which is v2.0.5. Found out the error will appear if you got two versions of Cocos Creator in the computer.
