Cannot Build Project

[Former user]

When I try to build the project I get the following error: "Error Building Player because scripts have compile errors in the editor". I am running 5.6.3p2

To reproduce the error simply create a new empty scene and import the Uduino asset and save the scene. Even in this simplest possible case you will get the error when you try building the project.

I could not reproduce the errror by importing Uduino asset. Did you run the initial configuration and/or manually set the .NET API compatibility ? (Set the API Compatibility level to .NET 2.0 (and not .Net 2.0 Subset). This setting is located under Edit\Project settings\Player. )

I have tried both and am still unable to build. I have also tried when the board is connected and disconnected, when the Uduino asset is placed into the scene, and when it is not, and nearly any other combination. When you tried reproducing the error, were you using the latest Unity 5.6.3p2?

There is another message in the console, right before the one mentioned above, that I did not notice previously:

" Assets/Uduino/Scripts/UduinoDevice.cs(2,7): error CS0246: The type or namespace name `UnityEditor' could not be found. Are you missing an assembly reference?"

"Error building Player because scripts had compiler errors"

I just found this which may be helpful: http://answers.unity3d.com/questions/316805/unityeditor-namespace-not-found.html

Oh I see, in the last update I added a reference to UnityEditor without adding the flag for building.

You can edit the script UduinoDevice.cs as following:

using UnityEngine;
#if UNITY_EDITOR
using UnityEditor;
#endif
using System.Collections;
using System.Collections.Generic;
using System.Linq;

            } set
            {
                if (_name == "")
                    _name = value;
