Building production using ng build --prod results with the following error:
ERROR in vendor.6524f61fda4d53a6f933.bundle.js from UglifyJs Unexpected token: name (Time) [vendor.6524f61fda4d53a6f933.bundle.js:18068,6]
I can’t find Time in my project path, i think it is from some of the libraries i use.
Before i updated Angular, and Angular CLI I used Angular 4.1.3 and Angular CLI 1.0.6 and I was getting similar error but insted of Time, unexpected token was PolicyMappings which was from pkijs
I also found Time class in pkijs

I have compilerOptions.target of es5 and still have ERROR from UglifyJS. I figured it’s because I’m using
pifypackage that’s ES6. Still haven’t found a solution yet.I changed compilerOptions.target from es6 to es5 and this error disappeared.
I’ve resolved this using UglifyJS2#harmony-v2.8.22 --dev for ES6:
yarn add git://github.com/mishoo/UglifyJS2#harmony-v2.8.22 --dev
documented at: https://www.npmjs.com/package/uglifyjs-webpack-plugin
I may have found the problem - I had a target of es6, because es5 was causing me problems with
this.allowedFields = [ ...new Set(this.allowedFields) ].sort((a,b) => { return a.toLowerCase() > b.toLowerCase() ? 1 : -1});I think that es6 does not compile properly with uglify.js , which may be throwing out the errors
Any idea on how I can get uglify to work with es6 ?
Upgrade to a newer version of angular-cli, this has been fixed for a little while now: https://github.com/angular/angular-cli/pull/7610
I changed compilerOptions.target from es6 to es5 and OK too.
I can confirm this issue. Only happens when I set the target to
es6. Usinges5the issue is not there.
