Current behavior

After a fresh git clone / npm install, I run npm run build:universal-prod

I get this issue 4 times.

Then :

Expected/desired behavior

Build files ready for universal production server.

Minimal reproduction of the problem with instructions
npm run build:universal-prod

Please tell us about your environment:

Mac OS, yarn.

• Angular version: 4.1.0

• Node (for AoT issues): node --version = 6.9.1

Thanks !

PS : it might be that I don't completely understand how to run production. If so, I can create a PR modifying the readme.

It's a known issue which arises today, this repo depends on the harmony branch of UglifyJs2 and it got somehow broken. If you visit the latest issues on that repo, you'll notice how everyone's builds are failing.

Commenting Uglify plugin from webpack config will help the prod build to be successful. Tomorrow, I'll have a look at the UglifyJs2 repo and try to solve this.

i have same issue

@Mahmoud-hassan87 i'm still collecting information on this topic, seems like the new of UglifyJS broke many things.

Stay tuned.

@theomathieubhvr @Mahmoud-hassan87 get the latest version and try to build. I temporarily commented the UglifyJs and it should run without a problem now.

Thanks ! That's working now.

I don't know what to do with this issue, renaming it or closing it ?

I'll let you decide.

Let's leave it because I could not reproduce it (using fulls1z3/webpack as a dependency). Let's keep this open for a few more days, and let's see.

I solved this by forcing the uglify-js deps to use version git://github.com/mishoo/UglifyJS2#harmony-v2.8.22.

Get the latest version of this repository, and remove webpack and uglify-js dirs from node_modules and run npm install/yarn et voila!
