I have same problem, and I already tried following this stuff and it works.

1. First, Install python 2.7
https://www.python.org/downloads/release/python-2718/ (choose : macOS 64-bit installer)

2. Create Class like this, put on folder "Assets > Editor > PreBuildProcessing.cs"

  #if UNITY_EDITOR
  using UnityEditor;
  using UnityEditor.Build;
  using UnityEditor.Build.Reporting;
  using UnityEngine;
  
  public class PreBuildProcessing : IPreprocessBuildWithReport
  {
      public int callbackOrder => 1;
      public void OnPreprocessBuild(BuildReport report)
      {
          System.Environment.SetEnvironmentVariable("EMSDK_PYTHON", "/Library/Frameworks/Python.framework/Versions/2.7/bin/python");
      }
  }
  #endif
