Running eslint in our repo fails for version 2.19.0 with this error TypeError: Cannot read property 'value' of null.
Rolling back to 2.18.2 resolves the issue.

It looks like the problem is potentially related to 99b3fbf. node.source is null in ExportNamedDeclaration, which causes the failure. It fails for export class Component extends React.Component { ... }, export function Component() { ... }, and export const Component = () => { ... }

Please let me know if there's more information I can share to help diagnose this issue.
