使用 pip 安装 PyGreSQL 失败

Question

我目前正在尝试使用 pip install PyGreSQL 安装 PyGreSQL，但是，当我运行命令时，出现以下错误：

Could not import setuptools which is required to install from a source distribution.
Traceback (most recent call last):
   File "/usr/local/lib/python2.7/site-packages/pip/req/req_install.py", line 375, in setup_py 
       import setuptools  # noqa
   File "/usr/local/lib/python2.7/site-packages/setuptools/__init__.py", line 11, in <module>
       from setuptools.extern.six.moves import filterfalse, map
   File "/usr/local/lib/python2.7/site-packages/setuptools/setuptools/__init__.py", line 12, in <module>
       from setuptools.extension import Extension
   File "/usr/local/lib/python2.7/site-packages/setuptools/extension.py", line 8, in <module>
       from setuptools.extern.six.moves import map
ImportError: No module named extern.six.moves

有谁知道可能出了什么问题？据我所知，extern.six.moves有问题，但是，我在网上找不到有关此的任何内容......

这最终是由于安装工具未正确安装在我的机器上。感谢@Famarri帮助我意识到这一点
