Hey Guys,

I've checked this case, and found a fix for that. It's problem with Typescript. I think, that it will be fixed in next TypeScript releases, but for now you can try to use solution of user 'gmavritsakis' added on GitHub: https://github.com/angular/angular-cli/issues/8434 .

In file 'typescript.js' located in: node_modules/typescript/lib

Replace all the function
function nodeCanBeDecorated(node)
with the following code:

function nodeCanBeDecorated(node) {
       switch (node.kind) {
           case 229 /* ClassDeclaration */:
               // classes are valid targets
               return true;
           case 149 /* PropertyDeclaration */:
               // property declarations are valid if their parent is a class declaration.
   			// return node.parent.kind === 229 /* ClassDeclaration */;
   			return (node.parent && node.parent.kind === 229) || (node.original && node.original.parent && node.original.parent.kind === 229);
           case 153 /* GetAccessor */:
           case 154 /* SetAccessor */:
           case 151 /* MethodDeclaration */:
               // if this method has a body and its parent is a class declaration, this is a valid target.
               return node.body !== undefined &&
   				// && node.parent.kind === 229 /* ClassDeclaration */;
   				(node.parent && node.parent.kind === 229) || (node.original && node.original.parent && node.original.parent.kind === 229);
           case 146 /* Parameter */:
               // if the parameter's parent has a body and its grandparent is a class declaration, this is a valid target;
               // return node.parent.body !== undefined
               //     && (node.parent.kind === 152 /* Constructor */
               //         || node.parent.kind === 151 /* MethodDeclaration */
               //         || node.parent.kind === 154 /* SetAccessor */)
   			//     && node.parent.parent.kind === 229 /* ClassDeclaration */;
   			
   			var parent = node.parent || (node.original && node.original.parent);
   			return parent && parent.body !== undefined &&
                     (parent.kind === 152
                        || parent.kind === 151
                        || parent.kind === 154) && parent.parent.kind === 229;
       }
       return false;
   }

I got this issue too but with latest angular stack on fresh new project. I doubt that this issue comes from @angular/cli because when I disabled  --aot and --build-optimizer, there is no error . Some code in MDBBootstrapModules cannot build in prod mode with --aot and --build-optimizer which is enabled by default in new @angular/cli. Please consider fixing your code because these build options is crucial. My environment: Angular CLI: 1.6.0 Node: 8.8.1 OS: linux x64 Angular: 5.1.0 ERROR in : TypeError: Cannot read property 'kind' of undefined at nodeCanBeDecorated (/home/hnguyen/webapp/node_modules/typescript/lib/typescript.js:7805:36)

Dear jimsgroup ,

There are quite a few known issues regarding the newest Angular and CLI, could you please try to downgrade your CLI to 1.5.0 ? We are continuously working with Angular team on that and adjusting our library to work correctly with the newest Angular however quite often we have to wait until Angular team fix something on their side.

For now, please either downgrade or comment following directive since you didn't use it, I hope that by the time we release next package (probably next week) this issue will be solved either on our or their side (depending on where the root cause actually is)
