pip - 在虚拟环境中安装 mysql for python

Question

我经历了其他类似的问题，但那里提到的东西都没有达到我的目的。我的操作系统是 ubuntu 11.04，我首先创建了一个虚拟环境：

virtualenv mysite

完成后，我安装了 django

pip install django==1.3

安装 django 后我尝试为 python 安装 mysql 接口：

pip install MySQL-python 

这给了我一个错误：

Downloading/unpacking MySQL-python
  Downloading MySQL-python-1.2.3.tar.gz (70Kb): 70Kb downloaded
  Running setup.py egg_info for package MySQL-python
    sh: mysql_config: not found

Traceback (most recent call last):

  File "<string>", line 14, in <module>

  File "/home/build/MySQL-python/setup.py", line 15, in <module>

    metadata, options = get_config()

  File "setup_posix.py", line 43, in get_config

    libs = mysql_config("libs_r")

  File "setup_posix.py", line 24, in mysql_config

    raise EnvironmentError("%s not found" % (mysql_config.path,))

EnvironmentError: mysql_config not found

我进一步尝试：

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

请帮忙，谢谢。
