 * `require.import` - An array of modules to be loaded into NodeVM on start.
 * `require.resolve` - An additional lookup function in case a module wasn't found in one of the traditional node lookup paths.

+* `require.strict` - `false` to disable loading modules in strict mode (default: `true`).
 * `nesting` - **WARNING**: Allowing this is a security risk as scripts can create a NodeVM which can require any host module. `true` to enable VMs nesting (default: `false`).
 * `wrapper` - `commonjs` (default) to wrap script into CommonJS wrapper, `none` to retrieve value returned by the script.
 * `argv` - Array to be passed to `process.argv`.
