python设置.py安装，virtualen内存不足

Question

我正在编写一个Python包，其中包含一些Cython代码。我用virtualenv。我写的时候，它编译得很好

$ source activate
$ python setup.py build_ext --inplace

但是，当我尝试安装这个软件包时，它开始消耗内存，直到我的计算机挂起（或者我之前终止了进程）。更具体地说，当我尝试：

^{pr2}$

我认为下面的[https://github.com/docker/docker/issues/10025][1]可能是问题的根源。基本上，在上面提到的问题中，它说了以下几点

I can replicate this issue. The above resolution does not suggest that changing Python versions fixed anything. It's the writing of files by setuptools that's causing it, though I don't know why. Sometimes it hangs for me when writing dependency_links.txt and sometimes SOURCES.txt. Will see if I can investigate further.

...

Haha, ok, the issue is that you're calling setup.py from / and distutils does a listdir('.') from the calling directory, so I assume it's walking the entire filesystem. So I guess, don't do that. https://github.com/python/cpython/blob/master/Lib/distutils/filelist.py#L245

我知道发生了什么事，但我不知道怎么解决这个问题。在

可能有用的进一步信息。在setup.py的内容下面

from setuptools import setup
from Cython.Build import cythonize

setup( name = 'ColoredHRG' ,
       version = '0.1' ,
       description = 'my package.' ,
       url = 'BLA BLA' ,
       author = 'BLA BLA' ,
       author_email = 'BLA BLA' ,
       license = 'GPL3' ,
       packages = [ 'ColoredHRG' ] ,
       ext_modules = cythonize( [ "ColoredHRG/ColoredHRG.pyx" ,
                                  "ColoredHRG/Pool.pyx" , 
                                  "ColoredHRG/MC.pyx" , 
                                  "ColoredHRG/EXAMPLE_traveling_salesman.pyx" , 
                                  "ColoredHRG/MC_ColoredHRG.pyx" ] ,
                                  language = 'c++' ) ,
                                  zip_safe = False )

我终于找到问题了。包的文件夹结构如下

ColoredHRG/setup.py
...
ColoredHRG/ColoredHRG/ColoredHRG.pyx
ColoredHRG/ColoredHRG/MC.pyx
...
ColoredHRG/ColoredHRG/examples/examples.py
...

另外，在文件夹examples中，有一个软链接（我在Linux中）指向位于该位置的文件夹

^{pr2}$

也就是说，软连接是

ColoredHRG/ColoredHRG/examples/DATA -> ../../DATA

结果是，不知何故，这会导致distutils进入一个无限递归循环，吃掉我计算机的整个内存，然后挂起。在

我删除了软链接，现在一切正常。在
