werkzeug.utils.ImportStringError: import_string() failed for ‘app.secure’. Possible reasons are:

• missing init.py in a package;
• package or module path not included in sys.path;
• duplicated package or module name taking precedence in sys.path;
• missing module, class, function or variable;

Debugged import:

• ‘app’ found in ‘D:\pythonTool\coding-194\app\init.py’.
• ‘app.secure’ not found.
