"Error: Cannot find module './lib/cloneBuffer'" when vinyl is a dependency of gulp-util

[immo-huneke-zuhlke]

Here is part of the console output log of a Jenkins build of my project. I have inserted two find commands in the build script just before invoking "gulp default" to show why vinyl's lib/cloneBuffer.js cannot be found. There are lots of copies of the file, just none on that subtree of node_modules. ...

This issue can be closed. It appears that there was a glitch while downloading the dependencies originally. Wiping out the node_modules folder and rerunning the build cleared the problem.
