导入错误：内的virtualenv

Question

尝试将的virtualenv中的Mac OSX上安装一个Python PIP包（Django的REST框架文档，drfdocs）在Mac OS X中没有名为setuptools.command模块：

这里有点子的相关版本，蟒蛇，easy_install的：

$ virtualenv --version 
1.11.4 

$ mkvirtualenv test 
New python executable in test/bin/python 
Installing setuptools, pip...done. 

(test)$ python --version; which python 
Python 2.7.10 
/Users/me/.virtualenvs/test/bin/python 

(test)$ pip --version; which pip 
pip 1.5.4 from /Users/me/.virtualenvs/test/lib/python2.7/site-packages (python 2.7) 
/Users/me/.virtualenvs/test/bin/pip 

(test)$ easy_install --version; which easy_install 
setuptools 2.2 
/Users/me/.virtualenvs/test/bin/easy_install 

(test)$ python -c "import setuptools.command; print setuptools.command" 
<module 'setuptools.command' from '/Users/me/.virtualenvs/test/lib/python2.7/site-packages/setuptools/command/__init__.pyc'> 

而这里的错误：

$ pip install drfdocs 
Downloading/unpacking drfdocs 
    Downloading drfdocs-0.0.11.tar.gz (771kB): 771kB downloaded 
    Running setup.py (path:/Users/me/.virtualenvs/test/build/drfdocs/setup.py) egg_info for package drfdocs 
    Traceback (most recent call last):

    Traceback (most recent call last): 

    File "<string>", line 3, in <module> 

ImportError: No module named setuptools.command 

---------------------------------------- 
Cleaning up... 
Command python setup.py egg_info failed with error code 1 in /Users/me/.virtualenvs/test/build/drfdocs 
Storing debug log for failure in /Users/me/.pip/pip.log 

我尝试了各种修正的其他堆栈溢出回答here，但没有工作。

$ pip install -U setuptools 

也没有帮助。

编辑：根据要求：

(test)$ python -c "import setuptools; print setuptools.__file__; print setuptools.__version__" 
/Users/me/.virtualenvs/test/lib/python2.7/site-packages/setuptools/__init__.pyc 
2.2 

---

编辑＃2：我想pip install pip --upgrade所以现在我对pip==8.1.2。

现在，当我尝试安装，我得到一个稍微不同的错误：

(test)$ python 
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

为什么这种情况发生，虽然仍是没有意义的。

Answer 1

这是一个包中的错误。请参见issue #120

等待v0.1.0或下载package from PyPI，从此软件包中删除site目录，然后安装打包的软件包。
