How to force Rollup to assemble assembly in one file?

Question

JavaScript

Good day.
There is Rollup 1.29, there is a simple config. You need to end up with a minified library file.

export default {
  input: 'src/index.js',
  plugins: [
    resolve({
      mainFields: ["module", "jsnext:main", "main", "browser"]
    }),
    vue({
      css: true,
    }),
    babel({
      exclude: 'node_modules/**',
      babelHelpers: 'runtime',
      extensions: ['.js', '.jsx', '.es6', '.es', '.mjs', '.vue'],
    }),
    cjs(),
    replace({
      VERSION: JSON.stringify(config.version),
    }),
    postcss(),
    terser(),
    analyze(),
  ],
  output: [{
    file: 'dist/libdary.min.js',
    format: 'es',
  }],
};

As a result, I get an error: " Error: You must set "output.dir" instead of "output.file" when generating multiple chunks ".

How to eliminate? I explicitly stated that I want one output file.
Thanks in advance.
