I’m using this plugin with vue-cli webpack template. And here is the code I added in webpack.prod.conf.js:

new PrerenderSpaPlugin(
   path.join(__dirname, '../dist'),
   ['/']
)

The first argument is the root of the built files which has the following file structure:

/dist
   |--- index.html
   |--- /static
        |--- /js
        |--- /css
        |--- /img

Also I came across the same error in the example you provide. I tried in Node v6.7.0 & v4.6.0

It sounds like phantomjs didn’t get installed correctly for whatever reason. You can try to install it again with:

$ cd node_modules/phantomjs-prebuilt
$ node install.js

I’ve had the same error and just npm rebuild command helped me! For some reason, npm reinstalling did not help…
