Question

我正在尝试在virualenv中安装memcached python绑定：

(env1)ubuntu@ip-172-31-28-196:~$ pip uninstall python-memcached
Cannot uninstall requirement python-memcached, not installed
(env1)ubuntu@ip-172-31-28-196:~$ pip install python-memcached
Collecting python-memcached
  Using cached python-memcached-1.53.tar.gz
    Traceback (most recent call last):

      File "/tmp/pip-build-x1yj76g5/python-memcached/setup.py", line 4, in <module>
        import memcache
    Complete output from command python setup.py egg_info:

      File "/tmp/pip-build-x1yj76g5/python-memcached/setup.py", line 4, in <module>    

        import memcache    

    ----------------------------------------

也许你需要先安装memcached？就像sudo apt-get install memcached一样
