I am getting this error as well on macOS Mojave 10.14.6 (Supplemental Update 2). Cloned from github, yarn install was successful, but yarn dev throws this error:

error An unexpected error occurred: "https://registry.yarnpkg.com/@mermaid-js%2fmermaid: Not found".
🚨 /mermaid-live-editor/src/components/Edit.js:5:20: Failed to install @mermaid-js/mermaid.

Same for me on ubuntu 18.04 :

yarn run v1.19.1
$ parcel ./index.html -d build

It looks like @mermaid-js/mermaid doesn't exist right now. I had to run "yard add mermaid" then change all the references to just mermaid instead of @mermaid-js/mermaid. Diff below. Oh, had to comment out the last change too. I'm sure this is not what the maintainers intended, but it got me up and running for now.
