Fixing Nuxt3 debugging errors in VSCode Dev Containers

2025/09/08に公開

Cannot start Nuxt in Dev Containers

I am developing a Nuxt 3 project using VSCode Dev Containers.

When I run npm run dev in that project, an error occurs and the browser screen goes completely white...

Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

After looking into it, I found a related Nuxt issue.

It seems there is an incompatibility between Dev Containers and Nuxt, and the issue can be avoided by adding --no-fork when starting the server.

package.json

{
  "scripts": {
    "dev": "nuxt dev",
    "dev:no-fork": "nuxt dev --no-fork",
  }
}

npm run dev:no-fork
# Executes nuxt dev --no-fork

I was able to start the debug mode successfully.

I have compiled the knowledge I gained from two and a half years of daily home development! Please take a look if you're interested.
