python - pip install --upgrade sqlalchemy 超出最大递归深度

Question

我试过pip install --upgrade sqlalchemy、python2.7 setup.py install，在删除site-packages中的sqlalchemy文件夹后，我已经试过 pip install sqlalchemy。他们都给出了“RuntimeError: maximum recursion depth exceeded in cmp”。

  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

我还尝试运行 v0.9 的 setup.py 并获得相同的结果。尝试向 setup.py 添加一行以将最大递归设置为 10000 和 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}

Answer 1

看起来我的“分发”(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 并安装它。

安装其他包时遇到同样的问题。
