Cannot build the package

[SylwesterKogowski]

Hi, I just cloned the repository and tried to build the documentation, but to no avail. Here is what I've done: Since I have the newest version of node, npm and angular (and this package doesn't work with newest angular-cli) I first did: npm install Here you can see the list of packages after installation: https://justpaste.it/6upjt

then I did: npm run build I got the following error: https://justpaste.it/6r8sb and here is the debug log https://justpaste.it/4e8y0
