On running npm run build, the following error occurs:

> svelte-devtools@1.0.0 build /Users/alacritas/Projects/Utils/svelte-devtools-master
> $npm_execpath run build:format && rollup -c && $npm_execpath run build:icon


> svelte-devtools@1.0.0 build:format /Users/alacritas/Projects/Utils/svelte-devtools-master
