Select2 causes the error of "Uncaught TypeError: undefined is not a function"

[JKChen]

The code of $('.select2').select2(); in common.js causes the error of "Uncaught TypeError: undefined is not a function".
Maybe you have load jQuery twice, and the second time when jQuery loaded it removes registered plugins.
Can you fix it?Thank you so much, and this is an awesome APP.

Set this line of code of $('.select2').select2(); as comments can bypass this problem.

Sorry, it's all my fault. Run gulp copyfiles before npm run dev can fix this fake error.
