Can't make it work with `.js`

[wesleycoder]

I'm installing it in a new machine and can't get it to work with the error:

$ pygmentize -l jsx dev/tavern-web/server.js 
*** Error while highlighting:
ValueError: No JSON object could be decoded
   (file "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode)
*** If this is a bug you want to report, please rerun with -v.

`dev/tavern-web/server.js` contents:

const next = require('next')
const { createServer } = require('http')
const { join } = require('path')
const { parse } = require('url')
const env = require('./config/env')
const app = next()

const handle = app.getRequestHandler()

const staticRoutes = ['/service-worker.js']

const { APP_PORT, PUBLIC_URL, NOW_URL, NODE_ENV } = env.raw
export const serve = async (appPort = APP_PORT, appUrl = (NOW_URL || PUBLIC_URL)) => {

let server

await app.prepare()

server = createServer((req, res) => {

const parsedUrl = parse(req.url, true)

const { pathname } = parsedUrl
if (staticRoutes.includes(pathname)) {
  const filePath = join(__dirname, '.next', pathname)

  app.serveStatic(req, res, filePath)
} else {
  handle(req, res, parsedUrl)
}

})

server.listen(appPort, () => console.log(> Ready on ${appUrl}))
return server

}
if (NODE_ENV !== 'test') {

serve()

}
export default serve
