**Solutions tried:** reinstalling the package

I've also re-produced this exact same issue on another linux machine.

Bắt đầu tại node_modules/@atom-ide-community/nuclide-commons-ui/Dropdown.js, khoảng dòng 45 và 305, sau đó lần theo các imports từ AutoGenLaunchAttachUiComponent.js và AutoGenLaunchAttachProvider.js được hiển thị trong stack trace. Tái hiện việc kích hoạt trên Arch Linux sau khi cập nhật và xác nhận rằng ide-python được kích hoạt mà không gặp lỗi getFileName.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
