How Do We Reproduce?

https://github.com/canvg/canvg/pull/1046#discussion_r423445163

Expected Behavior

Lookup @babel/plugin-transform-runtime over babelrc and presets.

Actual Behavior

With babelHelpers: 'runtime' @rollup/plugin-babel lookup @babel/plugin-transform-runtime only in plugin options, but plugin-transform-runtime is included in preset (or in babelrc).

src/index.ts → lib/index.js, lib/index.es.js...

I found a configuration method to avoid this error

babel({
    babelHelpers: 'runtime',
    skipPreflightCheck: true
})

but how do you compile the dependencies of babel runtime to a file? 😦

add exclude to config, it works for me

babel({    
  babelHelpers: 'runtime',
  exclude: '**/node_modules/**',
}),

babel({

  exclude: '**/node_modules/**',
}),

If it doesn’t work, use this one:

    babel({
        babelHelpers: 'runtime',
        exclude: /^(.+\/)?node_modules\/.+$/
    })

I’m still getting this.

I got the same error in pnpm workspaces

and solve it with skipPreflightCheck: 'true'

babel({
        babelHelpers: 'runtime',
        skipPreflightCheck: 'true',
        extensions: [...DEFAULT_EXTENSIONS, '.ts'],
        exclude: /^(.+\/)?node_modules\/.+$/,
      }),

@shellscape looks like @dangreen provided a reproduction. Does that suffice? Is there anything else you need from us?
