I have another issue. I try to precompile all assets but I get always this error.

RAILS_ENV=production rake assets:precompile --trace

Hi Markus,

what is output when you manually run cd frontend && npm run build ?

I assume that you do not have the npm frontend dependencies installed, or some other error happens during compilation of frontend assets (not enough RAM, possibly)

With that command I found many packages which were missing. However now I have another issue and I don't know why. It tells me that I have to install angulare/core. That I did and also the dependeny rxjs and zone.js but still doesn't work.

/usr/local/lib
├── @angular/core@8.2.13
├── UNMET PEER DEPENDENCY rxjs@^6.4.0
└── UNMET PEER DEPENDENCY zone.js@~0.9.1

npm WARN @angular/core@8.2.13 requires a peer of rxjs@^6.4.0 but none was installed.
npm WARN @angular/core@8.2.13 requires a peer of zone.js@~0.9.1 but none was installed.
root@myserver:~# npm install -g rxjs
/usr/local/lib
└── rxjs@6.5.3

root@myserver:~# npm install -g zone.js
/usr/local/lib
└── zone.js@0.10.2

openproject@myserver:/opt/openproject$ cd frontend && npm run build

> openproject-frontend@0.1.0 prebuild /opt/openproject/frontend
> ./scripts/link_plugin_placeholder.js


> openproject-frontend@0.1.0 build /opt/openproject/frontend

You seem to not be depending on "@angular/core" and/or "rxjs". This is an error.

Hi Markus,

let's make one step back. Why do you need to run assets:precompile?

• Do you have a packaged installation? In this case, the angular frontend has been removed deliberately as all assets are correctly compiled already. You will only need to install them again if you have a custom plugin that uses assets and requires compilation. You will likely not need it nor call to assets:precompile

My problem was that I couldn't see any pictures when I openend the webpage.
