[@snowpack/plugin-esbuild] Error: The service is no longer running

[js87zz]

I've used the snowpack as the dev server and it worked really well.
However, the problem have occurred since the new installation of dependencies while applying npm workspace to our monorepo project.
After updating the dependencies(and symlink), I got a error message like as below when running the snowpack dev server.

The same problem occurred when the environment of the project was rolled back and the snowpack dev server was re-run in a previously well-run environment.

I think there's conflict with the directory of the snowpack development server after applying the workspace. But I don't know the details.. so if you know how to solve this problem, Please let me know the solution.

/apps/editor/snowpack.config.js

module.exports = {
  mount: {
    'demo/esm': '/',
    'src/img': '/img',
    src: '/dist',
  },
  devOptions: {
    port: 8080,
  },
  buildOptions: {
    clean: true,
    sourceMaps: false,
    out: 'dist',
  },
  alias: {
    '@': './src',
    '@t': './types',
  },
};

/apps/editor/package.json

"scripts": {
  "serve": "snowpack dev --reload",
  ...
}

packge.json(monorepo root)

"devDependencies": {
  "snowpack": "^3.0.13",
  ...
},
"scripts": {
  "serve": "lerna run --stream --scope /apps/editor serve",
}

I'm currently running the following system:

• MacOS Mojave
• Node 15.4.0
• npm 7.0.5
• snowpack 3.0.13

Any suggestions or help is greatly appreciated!

To solve this problem, I looked at the issue of esbuild and found this solution. I should dig the exact cause more, but fortunately the error was resolved.
