The Buffer deprecation warning was tracked under #5477, and was fixed in Yarn v1.10.0.

Oh, after taking a closer look at that error message, it looks like the error you encountered is due to a misspelling. The Buffer warning was just a warning, and wasn't related to the error.

The package generator-hipster does not exist, so it failed to install. The package you meant to install is probably generator-jhipster.
