92% additional asset processing copy-webpack-plugin
When the project is being compiled, it will stuck at that last line reporting 92% of additional asset processing by copy-webpack-plugin.
Please help me to resolve this issue.
Maybe just try to stop ng serve and try it once again?
I used to run the command : tns run android --bundle. And when i saved the changes, they were automatically updated in the physical and virtual android emulators.
Now when i save the changes, nothing happens and have to run the command again to see the changes.
When i save the project, it appears the following message:

There were some bugs in the NativeScript CLI which prevents the Hot Module Reload (HMR) which should refresh the application in your emulators.
A quick fix is to run the command:
tns run android --no-hmr
Which practically restarts/reloads the application completely.
I deployed with angular-cli-ghpages, followed the steps:https://www.npmjs.com/package/angular-cli-ghpages
1.git remote add origin https://github.com/username/epositoryname.git
2.ng add angular-cli-ghpages
3.ng deploy
When excute deploy show me this:

I was having the same problem and this worked for me:
When deploying:
ng deploy --base-ref=/YourRepositoryName/
Substitute YourRepositoryName with the name of your project and be careful with the final /.
I hope it help you to solve the problem.
Hi I couldn't change size or divide vendor in nuxt what makes server doesn't want to load and after few seconds quit.
The issue is I was about introducing nuxt auth when the server unluckily returned this. terminal response is below.
Earlier everything works good but unexpectedly doesn't want to load and after few seconds server quits every time I tried to run this app.
In addition even after removing part of code before server runs good, this error still occurs or after creating new project vendor is still to big but everything works until exceeding size a bit by adding some file.
I found out this issue is connected to the size of the vendor and
tried to modify build in nuxt.config.js to change size of chunks or even try to divide it to smaller part but nothing works.
Does anybody know how to fix it?
Thanks in advance.

This is the relevant error:
ConcurrentCompilationError: You ran Webpack twice. Each instance only supports a single concurrent compilation at a time.
You're not doing anything wrong here, this is a regression caused by some combination of changes in aurelia-cli and webpack. See this github issue
In short, lazy mode is not working properly. The workaround is to always use the --watch flag with au run.
au run --watch should work.
