    I can't say for sure, but I appear to have run into the exact same problem when attempting to build my project for WebGL in Unity 2017.1.0f3. The build fails, and I receive the following three error messages (only the first line of each message is given for brevity):

    1) Failed running /Applications/Unity/
    2) Exception: /Applications/Unity/ did not run properly!
    3) UnityEditor.BuildPlayerWindow+BuildMethodException: Build failed with errors.
