What does npm WARN excluding symbolic link mean?

Question

What does npm WARN excluding symbolic link mean? And how do I make it go away?

Answer 1

The message is emitted when npm interacts with a TAR file.

When it detects that a symbolic link is being used, it will emit the warning. For example, an archive you're trying to install through npm may contain a symbolic link. Those links will not be created on your local file system and are ignored.
