the thingESP8266 connection problem

Kits

Hi, I’m trying to connect to The thingESP8266 via the Serial Basic as shown in the setup for programing the thing. I get the following error message when I try to compile with the Arduino IDE :

dyld: lazy symbol binding failed: Symbol not found: _getentropy
Referenced from: /Users/Alan/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3
Expected in: /usr/lib/libSystem.B.dylib

Expected in: /usr/lib/libSystem.B.dylib
signal: trace/BPT trap
Error compiling for board Generic ESP8266 Module.

The problem I notice at first is that the port isn’t available when the "Serial Basic " chip is plug into the USB port of the computer. When I plug in an Arduino it see it it and displays the port #, but nothing for the Serial Basic connection.

I have all the drives installed. HELP!!!

OK it looks like you have two separate unrelated issues.

The first I’ve never seen before, you might need to uninstall your boards and reinstall them to see if that clears up the compiling issue.

For the second issue, it could be a bad USB cable or that you’ve installed the wrong driver. Try a different USB cable first and make sure it’s a data USB cable, not just a phone charging cable. If you’re on windows, something should pop up in device manager when you plug the board in.
