Steps to reproduce the behavior

Using multiple rollup configs and extract css with css: false will emit this error on the last build.

import babel from 'rollup-plugin-babel'
import postcss from 'rollup-plugin-postcss'
import replace from 'rollup-plugin-replace'
import vuePlugin from 'rollup-plugin-vue'
import { uglify } from 'rollup-plugin-uglify'
import { eslint } from 'rollup-plugin-eslint'
import nodeResolve from 'rollup-plugin-node-resolve'

import pkg from './package.json'

const name = `tua-ui`
const banner = `/* ${name} version ${pkg.version} */`

const plugins = [
    eslint({ exclude: ['**.sass', '**.scss', '**.css'] }),
    vuePlugin({ css: false }),
    postcss({
        extract: `dist/${name}.css`,
        sourceMap: true,
        extensions: ['.sass','.scss', '.css'],
    }),
    nodeResolve({ jsnext: true, main: true, browser: true }),
    babel({
        extensions: ['.js', '.jsx', '.es6', '.es', '.mjs', '.vue'],
    }),
    replace({ __VERSION__: pkg.version }),
]

export default [{
    input: 'src/index.js',
    output: [{
        file: pkg.main,
        banner,
        format: 'cjs',
        exports: 'named',
    }, {
        file: pkg.module,
        banner,
        format: 'es',
    }],
    plugins,
    external: ['vue'],
}, {
    input: 'src/index.js',
    output: {
        file: pkg.browser,
        name: 'TuaUI',
        format: 'umd',
        exports: 'named',
        globals: { vue: 'Vue' },
    },
    plugins: [ ...plugins, uglify() ],
    external: ['vue'],
}]

I guess maybe because of this. Could it be an option?

needMap: true

I hit this issue last week, I do believe it has to do with the vue-component-compiler caching the results of source mapping and when it is called again the second time (for your second file) it gives an error. I fixed this by running my file roll ups in different processes.

needMap: false works for me...

Can confirm that works for me, any way we can make this configurable?
