installing error

Hi, I'm trying to install the multimap tool using this command: " npm install @github/multimap"

But I have this errors:

any help, please?

Thank you.

Start by reproducing `npm install @github/multimap` with the reported Linux, Node v8.10.0, and npm v3.5.2 environment, then inspect the repository's installation metadata and any relevant package tests. Done means the supported installation path succeeds or the issue is narrowed to a documented compatibility problem; no source file or test is identified in the report.
