Sphinx -python3 -m http.server-FileNotFoundError：[Errno 2]没有这样的文件或目录

Question

我的问题-如何找出丢失的文件/目录？

Python3 http服务器在本地提供Sphinx html文件，但随后突然停止提供它们-我在终端中收到此错误-不知道缺少哪个文件/目录？

/pycon-sphinx-tutorial/crawler/docs/_build/html$ python3 -m http.server 8989

Answer 1

如您所见，正在从os.getcwd()中引发异常。这将建议您或其他进程删除服务器运行时正在提供文件的目录。如果当前工作目录已删除，则随后对os.getcwd()的调用将引发FileNotFound。例如：

>>> import os
>>> os.mkdir('a')
>>> os.chdir('a')
>>> os.getcwd()
'/blah/blah/blah/a'
>>> os.rmdir(os.getcwd())
>>> os.getcwd()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
FileNotFoundError: [Errno 2] No such file or directory

所以我想，不要那样做。
