Answer 1

I see you've cranked out a lot of code, however, it's littered with syntax errors. I'd recommend you try writing smaller chunks at a time, getting each step working as you plug along.

First, your while loop is infinte.

Second, if you want to use parenthesis with print (which I recommend), for Python 2.x, use this at the top of your files:

from future import print_function

Third, you should always use os.path for portable filesystem path manipulations.

What your error means is that, somewhere, you're trying to add a None type with a string. That's not possible, of course, so Python throws an exception. What you need to do, is to figure out why whatever you're adding is None, and fix that ;)

Hope that helps!

Answer 2

您可能需要设置环境变量DOMAIN_HOME或将System.getenv('DOMAIN_HOME')更改为System.getenv('DOMAIN_HOME', '.')等。
