NodeMCU ESP8266 SDCard issue

Hi
First of all - sorry for bad English

I try to connect SDCard to NodeMCU with Espruino 1.96 firmware with this manual

function onInit() {
  // initialise SPI1 for SDCard module
  SPI1.setup({mosi:NodeMCU.D6, miso:NodeMCU.D7, sck:NodeMCU.D5});
  E.connectSDCard(SPI1, NodeMCU.D0 /*CS*/);
  console.log(require("fs").readdirSync())­;
  // ...
}

bu as result - i see this in console:

Uncaught Error: Function "connectSDCard" not found!
at line 2 col 5
  E.connectSDCard(SPI1, NodeMCU.D0 /*CS*/);
    ^
in function called from system

what i do wrong?
thanks
