Pyramid Project: “ValueError: Variable assignment…” when trying to pserve

问题

I get the following error when trying to run a Pyramid project. As far as I'm aware, this appeared overnight, and I've no idea how to begin to debug this:

C:\mas\mas>..\Scripts\pserve.exe serve development.ini --reload
Starting subprocess with file monitor
Traceback (most recent call last):
  File "C:\mas\Scripts\pserve-script.py", line 8, in <module>
    load_entry_point('pyramid==1.3.2', 'console_scripts', 'pserve')()
  File "C:\mas\lib\site-packages\pyramid-1.3.2-py2.7.egg\pyramid\scripts\pserve.
py", line 47, in main
    return command.run()
  File "C:\mas\lib\site-packages\pyramid-1.3.2-py2.7.egg\pyramid\scripts\pserve.
py", line 221, in run
    vars = self.parse_vars(restvars)
  File "C:\mas\lib\site-packages\pyramid-1.3.2-py2.7.egg\pyramid\scripts\pserve.
py", line 330, in parse_vars
    % arg)
ValueError: Variable assignment 'development.ini' invalid (no "=")

What is the problem, or how a should I go about determining it? Sorry my question is rather vague, but if I had any more an idea of what I was asking I may have found the answer on Google :).

Line 328 - 330:

        raise ValueError(
            'Variable assignment %r invalid (no "=")'
            % arg)

It appears that you have the order of the arguments backwards - it should be:

..\Scripts\pserve.exe development.ini --reload

Ich, I'e worked it out, I was looking for the problem in the wrong place. the problem is this command:

..\Scripts\pserve.exe serve development.ini --reload

Should be this command:

..\Scripts\pserve.exe development.ini --reload

I have no idea how or when my batch file got changed, but if someone has a similar problem hopefully this will help.
