[maxbruggem]

Steps to reproduce:
Create a new directory and npm --init
npm install --save plotly.js

npm ERR! Error while executing:
npm ERR! C:\Program Files\Git\cmd\git.EXE ls-remote -h -t ssh://[email protected]/mapbox/mapbox-gl-style-spec.git
npm ERR!
npm ERR! Host key verification failed.
npm ERR! fatal: Could not read from remote repository.
npm ERR!

Also fails with yarn. Performing the action:
yarn add plotly.js
gives the error:
error Couldn't find match for "83b1a3e5837d785af582efd5ed1a212f2df6a4ae" in "_c" for "https://github.com/mapbox/mapbox-gl-style-spec.git".

What version of npm are you using ❓

Might be related to #1745

[maxbruggem]

npm version 5.5.1

The issue seems to be with these lines that install dependencies from github directly. It looks like there's a problem fetching those via ssh. It's not quite the same as this issue, but perhaps similar.

To solve, this, it looks like a couple places to start would be:

1. ~/.ssh/known_hosts (or the windows equivalent). Sometimes out-of-sync keys there can cause otherwise fine ssh operations to fail. Sometimes you just have to delete offending entries.
2. Do you have a github account? I wonder if that's necessary in order for it to fetch npm modules from github via ssh. If necessary, it might be possible to just create a dummy account and set up ssh.

It looks like having a github account setup with ssh keys is necessary. I setup my github account to recognise the ssh keys on my computer and was able to install the package successfully. Closing this issue because install was successful.

I'm seeing something similar with a self-signed cert using yarn:

I think it's due to the way plotly is gathering its dependencies.
