This is probably a problem with your environment, please try to install:

npm install --global --production windows-build-tools

...and try again.

I have the same issue and the solution from @werthdavid did not work.
I found out that the issue is in @zxing-web/library with sharp 0.19.1. With sharp 0.20.0 the issue does not appear. I created a PR https://github.com/zxing-web/library/pull/10

[odahcam]

I see your problem, but this is in fact a environment problem. The sharp package is not friendly for Windows environments (or for any environment, maybe).

I had this problem too in the past and it is a pain in the ass and very hard to track down the real problem to solve.

I merged the @Nightapes PR at @zxing-web/library repo and I will publish the package ASAP. But keep in mind that the error may not disappear, as it is an environment issue that has nothing to do with @angular/cli.

Just to share with you guys, this is what happens when npm install in zxing library:
