Why appear "Uncaught Error: Module XXX not found" always ?

I connect SD Card to ESP8266 via SPI, and try to init SD Card by:

var spi = new SPI();
spi.setup({mosi:D13, miso:D12, sck:D14});
E.connectSDCard(spi, D15);

but appear "Uncaught Error: Function "connectSDCard" not found!"
Is't the "connectSDCard" function only available on some Original Espruino board build ?

Thanks.
