Windows 7
python 2.7(together with python 3.5 so I use py -2 to launch python 2.7 )

Have you had this problem repeatedly, or just the one time?

It looks like a problem with connecting to the server that runs compilation, so it might be transient.

For context, here are the docs on the closure compiler service: https://developers.google.com/closure/compiler/docs/api-tutorial1

I had this problem repeatedly. I have tried reinstall python 2.7 and scratch-block, but it didn't work

@zyctinker , All you need is a VPN, the appspot got block in china mainland~

[joseeph]

indeed facing the same issue, couldn't get the compressed library build, even though vpn is on

You can also use the offline closure compiler if you're frequently rebuilding.

Instructions for using the offline compiler are now live: https://developers.google.com/blockly/guides/modify/web/advanced
