Like the title says, I cannot upload my code to the ESP8266 / ESP-12F.
This is my first time trying something like this so I don't have any knowledge about any of this.
When I click on upload, I get the following error:

Error compiling for board NodeMCU 0.9 (ESP-12 Module).


I don't know what the error is and havent found anyone with a similar problem yet.

This is not an upload problem; it's a compilation problem: "The system cannot find the file specified."
I guess you're missing a library that your sketch needs.
Try a Google search for each of the files listed in the error report, to find what library is missing.
