Additional comments

By tracking down the bug locally in node_modules\@nuxt\utils\dist\utils.js
on line 1752: const match = asString.match(/^([^{(]+)=>\s(.)/s);
line 1754: const fullFunctionBody = match[2].match(/^{?(\sreturn\s+)?(.?)}?$/s);
and line 1756: if (fullFunctionBody[1] || !match[2].trim().match(/^\s*{/s))
and removing the s flag from these three lines, npm run dev worked prefect.

What Node.js version do you use?

[Botre]

I ran into the same issue with both the _nuxt_ and _nuxt generate_ commands.

OS: MS Windows 10 Pro 64-bits
Node version: 8.16

Upgrading to Node 10.15 fixed it for me.

[philBrown]

Should probably add

"engines": {
  "node": ">=10.0.0"
}

to your package.json

[clarkdo]

Fixed in #5608 , fix will be included in next release

[alanaasmaa]

Had same issue, upgrading node.js fixed it.

I have:

• nuxtjs v2.10.2
• OS Ubuntu
• npm v6.12.0
• node v10.15.3
  and, when running npm run generate I get SyntaxError: invalid regexp group.
  Instead, npm run dev works fine in my case!
  Does anyone have the same issue?
