Strange hidden npm packages (autoprefixer postcss-cli postcss)

support

Hi,
I have a very strange issue with the all famous postcss and autoprefixer libraries.
Even if I install them with npm install -G autoprefixer postcss-cli postcss or npm install autoprefixer postcss-cli postcss the command hugo --gc --minify always complains about the missing autoprefixer module.
I’m using hugo v0.92.2+extended linux/amd64 BuildDate=2023-01-31T11:11:57Z VendorInfo=ubuntu:0.92.2-1ubuntu0.1, node v16.20.2 and npm 8.19.4. Can this be some version issue?
