我从网站上安装了Pang和Python 2.7.8的Django 1.6.5.

我运行django-admin.py startproject test123,切换到test123目录,并运行命令python manage.py runserver,然后我得到这个：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/Library/Python/2.7/site-packages/Django-1.6.5-py2.7.egg/django/core/management/__init__.py", line 399, in execute_from_command_line
    utility.execute()

    apps = settings.INSTALLED_APPS

    self._setup(name)

    from django.views.debug import ExceptionReporter, get_exception_reporter_filter

    from django.http import (HttpResponse, HttpResponseServerError,
  File "/Library/Python/2.7/site-packages/Django-1.6.5-py2.7.egg/django/http/__init__.py", line 2, in <module>
    from django.http.request import (HttpRequest, QueryDict, UnreadablePostError,
  File "/Library/Python/2.7/site-packages/Django-1.6.5-py2.7.egg/django/http/request.py", line 11, in <module>
    from django.core import signing
  File "/Library/Python/2.7/site-packages/Django-1.6.5-py2.7.egg/django/core/signing.py", line 45, in <module>
    from django.utils.crypto import constant_time_compare, salted_hmac
  File "/Library/Python/2.7/site-packages/Django-1.6.5-py2.7.egg/django/utils/crypto.py", line 6, in <module>
    import hmac
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/hmac.py", line 8, in <module>
    from operator import _compare_digest as compare_digest
ImportError: cannot import name _compare_digest

发现该运算符是一个标准的python库.为什么不能导入呢？

附：我在命令行中尝试过,我可以导入运算符模块,但是我在这个语句中得到一个错误：来自operator import _compare_digest作为compare_digest

解决方法:

跟着这个SO回答：
Uninstall python.org version of python2.7 in favor of default OS X python2.7

然后将我的.bash_profile Python路径更改为/usr/lib / python以获取默认的OSX python路径.

卸载了Django和MySQL-Python：

sudo pip uninstall django
sudo pip uninstall MySQL-Python

然后再次重新安装一切,但MySQL-Python是第一个和第二个Django.

完成这些步骤后,一切正常.
