无法导入名称_parse_proxy (urllib2)

Question

我试着在Python 2中使用Scrapy，我得到了这个错误，

 File "/Library/Python/2.7/site-packages/twisted/internet/defer.py", line 1386, in _inlineCallbacks
    result = g.send(result)
  File "/Library/Python/2.7/site-packages/scrapy/crawler.py", line 95, in crawl
    six.reraise(*exc_info)
  File "/Library/Python/2.7/site-packages/scrapy/crawler.py", line 77, in crawl
    self.engine = self._create_engine()
  File "/Library/Python/2.7/site-packages/scrapy/crawler.py", line 102, in _create_engine
    return ExecutionEngine(self, lambda _: self.stop())
  File "/Library/Python/2.7/site-packages/scrapy/core/engine.py", line 69, in __init__
    self.downloader = downloader_cls(crawler)
  File "/Library/Python/2.7/site-packages/scrapy/core/downloader/__init__.py", line 88, in __init__
    self.middleware = DownloaderMiddlewareManager.from_crawler(crawler)
  File "/Library/Python/2.7/site-packages/scrapy/middleware.py", line 58, in from_crawler
    return cls.from_settings(crawler.settings, crawler)
  File "/Library/Python/2.7/site-packages/scrapy/middleware.py", line 34, in from_settings
    mwcls = load_object(clspath)
  File "/Library/Python/2.7/site-packages/scrapy/utils/misc.py", line 44, in load_object
    mod = import_module(module)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/Library/Python/2.7/site-packages/scrapy/downloadermiddlewares/httpproxy.py", line 4, in <module>
    from urllib2 import _parse_proxy
ImportError: cannot import name _parse_proxy

我安装了urllib2

我已经尝试过卸载并重新安装urllib2和requests。

您可能有两个不同的Python环境。Scrapy似乎住在/Library/Python/2.7/site-packages/scrapy，而你的urllib2住在/usr/local/lib/python2.7/site-packages。
