I'm experiencing the same issue, in my case it can be stuck on sealing for 5-10 min before it moves on.

Same problem...

[mtekkie]

I have the same problem.

I have same issue, could you check webpack version? The issue shows up starting from webpack@^3.7. For webpack 3.6, sealing takes only seconds.

@bingzheyuan I checked that.. @angular/cli@1.4.9 uses webpack@3.7.1

I also have the same issue and almost are very sure that the problem is with the Webpack. Downgrade to @angular/cli@1.4.6 helped.

This does sound like a problem in the new webpack versions. We updated to 3.7.1 in #8014 and 3.8.1 in #8132.

3.8.1 might fix this, but it wasn't released in 1.4.9. It should be in 1.5.0 final that is coming out very soon, and you can also try out 1.5.0-rc.3 meanwhile.

[kkudryaev]

Thanks. It works on 1.5.0-rc.3 and node 6.11.0.

[nashmaniac]

yes. it works a lot faster than the previous.

[elvisbegovic]

works faster only for this 71% step not faster globally , be clear

[nashmaniac]

yes. lastly my build would take about 11.5 mins now it's taking 2.5 mins. lot improved on that perspective. but it's not fast like the earlier versions.

[elvisbegovic]

I confirm in v1.5.0-rc.3 it doesn't block a lot on 71%, now I have little blocking at step
76% basic chunk optimization donno whats done here...

here you are:

this is without aot of course
