我正试图在Python 3.7中运行这段代码:
import web
urls = ('/', 'index')
if __name__ == "__main__":
app = web.application(urls, globals())
app.run()
每次都给我这个错误:
C:\Users\aidke\Desktop>python app.py
Traceback (most recent call last):
File "C:\Users\aidke\AppData\Local\Programs\Python\Python37-32\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 "app.py", line 14, in <module>
app = web.application(urls, globals())
File "C:\Users\aidke\AppData\Local\Programs\Python\Python37-32\lib\site-packages\web\application.py", line 62, in __init__
self.init_mapping(mapping)
File "C:\Users\aidke\AppData\Local\Programs\Python\Python37-32\lib\site-packages\web\application.py", line 130, in init_mapping
self.mapping = list(utils.group(mapping, 2))
File "C:\Users\aidke\AppData\Local\Programs\Python\Python37-32\lib\site-packages\web\utils.py", line 531, in group
x = list(take(seq, size))
RuntimeError: generator raised StopIteration
我尝试了别人的代码,结果出现了完全相同的问题。此外,我还尝试重新安装web.py(实验版),但仍然无法解决问题。
