我无法通过运行 “python startup.py” 来下载 “enron_mail_20150507.tar.gz”。我遇到了以下错误，并且不知道如何解决。

    downloading the Enron dataset (this may take a while)    to check on progress, you can cd up one level, then execute <ls -lthr>    Enron dataset should be last item on the list, along with its current     size    download will complete at about 423 MB    Traceback (most recent call last):    File "startup.py", line 36, in    urllib.urlretrieve(url, filename="../enron_mail_20150507.tar.gz")    File "C:\Python27\lib\urllib.py", line 98, in urlretrieve    return opener.retrieve(url, filename, reporthook, data)    File "C:\Python27\lib\urllib.py", line 245, in retrieve    fp = self.open(url, data)    File "C:\Python27\lib\urllib.py", line 213, in open    return getattr(self, name)(url)    File "C:\Python27\lib\urllib.py", line 350, in open_http    h.endheaders(data)    File "C:\Python27\lib\httplib.py", line 1049, in endheaders    self._send_output(message_body)    File "C:\Python27\lib\httplib.py", line 893, in _send_output    self.send(msg)    File "C:\Python27\lib\httplib.py", line 855, in send    self.connect()    File "C:\Python27\lib\httplib.py", line 832, in connect    self.timeout, self.source_address)    File "C:\Python27\lib\socket.py", line 557, in create_connection    for res in getaddrinfo(host, port, 0, SOCK_STREAM):    IOError: [Errno socket error] [Errno 11001] getaddrinfo failed

我尝试在 “startup.py” 中更改了 URL 为 ” http://www.cs.cmu.edu/~enron/enron_mail_20150507.tar.gz“，但还是不行。如果有人在 Windows 上使用 Python 成功下载了这个文件，请告诉我方法。我非常感激。

无论如何，我尝试手动下载，但文件在下载了 1.1 GB 后还在继续下载，所以我害怕了就停止了…哈哈 XD。”enron_mail_20150507.tar.gz” 文件有多大？下载后我应该把它放在哪里？在 ud120-projects 里吗？

请帮助我。我卡住了。

回答：

问题已经解决。我通过 starup.py 中的链接手动下载了文件，文件大小为 1.69 GB（压缩后）和 2.23 GB（解压后）。
