Question

我已经安装了一个python库MySQLdb，它在昨天工作。但是今天当我试图运行它时，它继续如下：

czhao@opx790:~$ python
Python 2.7.7 |Anaconda 2.0.1 (64-bit)| (default, Jun  2 2014, 12:34:02) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named MySQLdb

这真的很奇怪，所以我尝试重新安装它，但似乎我的计算机上有这个库：

czhao@opx790:~$ sudo apt-get install python-mysqldb
[sudo] password for czhao:

Use 'apt-get autoremove' to remove them.

我不知道为什么，我有图书馆，但python一直告诉我，我没有它。

您正在使用Anaconda Python，但是为系统Python安装了随apt-get安装的软件包。这两个不同的发行版具有不同的库目录，因此安装了一个的软件包/模块不可用于另一个。

要解决此问题，请使用Anaconda附带的pip程序并运行sudo pip install MySQL-python。

为什么我不能使用已安装的模块进行python？
