Namespace "goog.string" already declared.

I'm not sure what recently changed, but even after clearing my node_modules folder, I can't run my app, and always get this error in the console.

Uncaught Error: Namespace "goog.string" already declared.

https://www.bountysource.com/issues/47630631-multiple-declarations-of-goog-string-with-webpack-and-soy Fixed it.

Nice catch, @ssmith353!

We actually attempted to fix that lately in 58dec82, so I'd venture that you are not getting the latest 2.16.5 versions of those packages. Otherwise I would expect this to work even if webpack was failing to dedupe them...

hey @jbalsas,
I updated to latest 2.16.5, but thats actually when it broke. Even after clearing cache, updating npm, and clearing/reinstalling many times. The issue persisted. But it looks like the guide you posted to resolved the issue!

Thanks!

Could you send me a link to the code via mail so I can take a look? THanks!
