python - centos7.3上无法安装mysqlclient

Question

当我使用pip安装mysqlclient时，显示找不到mysql_config:

   [root@iZus9gnp1cZ local]# pip install mysqlclient Collecting mysqlclient   Downloading http://mirrors.aliyun.com/pypi/packages/6f/86/bad31f1c1bb0cc99e88ca2adb7cb5c71f7a6540c1bb001480513de76a931/mysqlclient-1.3.12.tar.gz (89kB)

        metadata, options = get_config()
      File "setup_posix.py", line 44, in get_config
        libs = mysql_config("libs_r")
      File "setup_posix.py", line 26, in mysql_config
        raise EnvironmentError("%s not found" % (mysql_config.path,))
    EnvironmentError: mysql_config not found

    ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-OJR4Al/mysqlclient/

谷歌之后，我找到了一些建议sudo yum install python-devel mysql-devel

但没有成功:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我的centos版本是7.3，python 3.4.2

我在安装mysql之前重新安装了它，它可以工作!我猜这个命令“yum -y remove mysql57-community-release-el7-10.noarch”会破坏环境文件。
