问题
I have a local Angular git repository that I build using Angular AOT (4.4.4) and everything works when I copy and paste the results to the server. However, when I clone the repo and do the same commands everything works (all of the build steps) until I bring up the site after pasting the changes to the server and I get the following error before the site loads.

I tried doing some google searches and I think it has something to do with socket.io. I'm not using socket.io directly and it is hard to find anyone with a relatable issue. Any ideas why this error is occuring in a fresh repo clone with Angular AOT?
回答1:
My problem was in 'rollup' (used in the AOT build process). My version of rollup in 'package.json' was "^0.50.1".
See here: https://github.com/rollup/rollup/issues/1706 Apparently this was fixed in 0.51.3. My guess is it was a typo (should have been 'io')...
Current (2018-03-29) version of rollup is 0.57.1. So I updated my 'package.json' and ran 'npm install rollup'. Compiled and ran OK, but encountered the message: "Unknown input option: sourceMap" during build. Likely a deprecated option, so I deleted "sourceMap: false," from 'rollup.config.js'.
All good now.
