 * Make sure you have boot9.bin and movable.sed in the rebuild folder
 * Make sure the SD card is inserted and you can view and edit its contents
 * ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'
 * Make sure you are in the rebuild folder and that you extracted the contents of rebuild-title-database-master.zip in it
 * When you fix this, delete the out folder and try the failing command again
