EnvironmentError：找不到mysql_config，安装MySQL-python时

有人可以告诉我该做什么吗？我从我这边做了以下事情：

使用pip安装时出错：

  ubuntu12.04@ubuntu12.04:~$ sudo pip install MySQL-python
    Downloading/unpacking MySQL-python
    Downloading MySQL-python-1.2.4.zip (113kB): 113kB downloaded

    libs = mysql_config("libs_r")

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

我在我的电脑上运行 UBUNTU 12.04 LTS 。

手动安装会产生相同的错误。我试过easy_install，它也没有帮助。

我手动搜索 mysql_config ，我无法在系统文件的任何位置找到它。

快速搜索后，我发现 mysql_config 属于 libmysqlclient-dev 。所以，我尝试使用以下方法获取这些包：

 sudo apt-get install libmysqlclient-dev

它给出了以下输出：

  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package libmysqlclient-dev is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  However the following packages replace it:
  mysql-server-5.5

  E: Package 'libmysqlclient-dev' has no installation candidate

我甚至从源代码下载了libmysqlclient-dev软件包，并尝试手动安装它们，它给出了依赖性错误。以下是安装时的输出。

  ubuntu@ubuntu:~/Downloads$ sudo dpkg -i libmysqlclient-dev_5.5.32-            0ubuntu0.12.04.1_amd64.deb 
  Selecting previously unselected package libmysqlclient-dev.

Answer 1

总结其他SO问题中提供的一些解决方案（并基于错误输出）。首先，

sudo apt-get update

它的作用是

用于从源代码重新同步包索引文件。可用包的索引是从/etc/apt/sources.list(5）中指定的位置获取的。

可以解决

dpkg：依赖性问题阻止配置libmysqlclient-dev

如果sudo apt-get install libmysqlclient-dev仍然不起作用

，请在之后运行以下内容

sudo apt-get install python-dev

sudo apt-get install python-mysqldb

最后，检查mysql_config中是否有PATH;必要时添加

export PATH=$PATH:/path/to/your/mysql_config

可能解决

EnvironmentError：找不到mysql_config

Answer 2

尝试添加apt-get源列表，并使用apt-get进行安装，这可能会阻止dpkg错误。
