pip install --upgrade sqlalchemy超出了最大递归深度

Question

我试过了pip install --upgrade sqlalchemy,python2.7 setup.py install在删除site-packages中的sqlalchemy文件夹之后,我试过了pip install sqlalchemy.它们都给出了"RuntimeError:cmp中超出了最大递归深度".

  File "C:\Python27\lib\ntpath.py", line 200, in splitext
return genericpath._splitext(p, sep, altsep, extsep)
  File "C:\Python27\lib\genericpath.py", line 102, in _splitext
    sepIndex = max(sepIndex, altsepIndex)
RuntimeError: maximum recursion depth exceeded in cmp

我还试图为v0.9运行setup.py并获得相同的结果.尝试在setup.py中添加一行以将最大递归设置为10000并且python崩溃.

编辑:回溯是一个很长的重复:

 File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\setuptools\dist.py", line 225, in __init__
    _Distribution.__init__(self,attrs)
  File "c:\python27\lib\distutils\dist.py", line 287, in __init__
    self.finalize_options()
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\setuptools\dist.py", line 257, in finalize_options
    ep.require(installer=self.fetch_build_egg)
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\pkg_resources.py", line 2029, in require
    working_set.resolve(self.dist.requires(self.extras),env,installer))
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\pkg_resources.py", line 580, in resolve
    dist = best[req.key] = env.best_match(req, self, installer)
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\pkg_resources.py", line 825, in best_match
    return self.obtain(req, installer) # try and download/install
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\pkg_resources.py", line 837, in obtain
    return installer(requirement)
  File "c:\python27\lib\site-packages\distribute-0.6.28-py2.7.egg\setuptools\dist.py", line 272, in fetch_build_egg
    dist = self.__class__({'script_args':['easy_install']})
{repeat until max recursion}

看起来我的"发行"(v0.6xxx)已经过时了.我跑了

pip install --upgrade distribute 

它安装了0.7.3.

然后运行pip install sqlalchemy并安装.

安装其他包时遇到同样的问题.
