Hallo and greetings to every XOD user out there,
this is not really a reply to the topic, but a more detailed information concerning the problem of compiling and uploading to a clone “AZ-Delivery NodeMCU Lolin V3” NodeMCU 1.0 (ESP12E Module) with CH340-Chip .
Im working on Windows 7 having installed the latest XOD version 0.37.3
The NodeMCU- board makes no trouble being programed via Arduino IDE.
I start with a simple patch like this.
For two or three times I can compile and upload patches like that but suddenly the compiler produces errors .
Even the simplest code can not be compiled any more.
Errorcode looks like so:
Begin compiling code for the board NodeMCU 1.0 (ESP-12E Module) 
Traceback (most recent call last):

Another try to compile that simple patch 
The compiler works just fine->

But the Upload fails:

I am totally confused about what happens here! Please can somebody help me.
To me it seems like an issue within the compiler for the NodeMCU and ESP 8266 because I have the same kind problems programing D1mini clones.
No Problems with Arduino- boards
I’d be thankfull for any suggestion to solve that mystery
