E:\pycharmProject\venv\Scripts\python.exe E:/pycharmProject/hello.py
Traceback (most recent call last):
File "E:\pycharmProject\venv\lib\site-packages\web\utils.py", line 526, in take
yield next(seq)
StopIteration
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "E:/pycharmProject/hello.py", line 6, in <module>
app = web.application(urls, globals())
File "E:\pycharmProject\venv\lib\site-packages\web\application.py", line 62, in __init__
self.init_mapping(mapping)
File "E:\pycharmProject\venv\lib\site-packages\web\application.py", line 130, in init_mapping
self.mapping = list(utils.group(mapping, 2))
File "E:\pycharmProject\venv\lib\site-packages\web\utils.py", line 531, in group
x = list(take(seq, size))
RuntimeError: generator raised StopIteration

错误原因，python3以上安装执行应pip install web.py==0.40-dev1，还要修改utils文件的526行
yield next(seq)
to:
try: yield next(seq) except StopIteration: return
做这个之前，请先卸载之前的安装pip uninstall web.py

To judge from the file paths, it looks like you're running Python 3.7. If so, you're getting caught by new-in-3.7 behavior described here:
PEP 479 is enabled for all code in Python 3.7, meaning that StopIteration exceptions raised directly or indirectly in coroutines and generators are transformed into RuntimeError exceptions. (Contributed by Yury Selivanov in bpo-32670.)
Before this change, a
StopIterationraised by, or passing through, a generator simply ended the generator's useful life (the exception was silently swallowed). The module you're using will have to be recoded to work as intended with 3.7.Chances are they'll need to change:
yield next(seq)
to:
try: yield next(seq) except StopIteration: return
