首先,是的,我已经看到了这个:

pip install mysql-python因EnvironmentError失败:找不到mysql_config

问题

我正在尝试在Google App Engine项目上使用Django.但是,由于以下原因导致服务器无法正常启动,因此我无法启动:

ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb

我做了一些研究,这一切都指向必须安装Mysql-python,因为显然它不在我的系统上.我实际上尝试卸载它并得到了这个:

Cannot uninstall requirement mysql-python, not installed

每当我确实尝试通过以下方式安装时:

sudo pip install MySQL-python

我收到一个错误说明:

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

我已经尝试过跑:

export PATH=$PATH:/usr/local/mysql/bin

但这似乎没有帮助,因为我再次运行安装命令但它仍然失败.

有任何想法吗？

请注意我不是一个虚拟的人.

用Homebrew安装MySQL和Python

我在OS X 10.10.5 Yosemite上用Homebrew安装了MySQL和Python.我的Python 2.7 python -> ../Cellar/python/2.7.9/bin/python带有一个符号链接/usr/local/bin/python.

在/usr/local/bin有一个符号链接:
mysql -> ../Cellar/mysql/5.7.9/bin/mysql

错误

在Python shell中:

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/_mysql.so, 2): Library not loaded: /usr/local/lib/libmysqlclient.18.dylib
  Referenced from: /usr/local/lib/python2.7/site-packages/_mysql.so
  Reason: image not found

所以我尝试过:
$ sudo unlink /usr/local/lib/libmysqlclient.18.dylib

其次是:
DYLD_LIBRARY_PATH=/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH

然后(对理性的绝望):
$ export DYLD_LIBRARY_PATH=/usr/local/Cellar/mysql/5.7.9/lib

但在这两种情况下import MySQLdb仍然试图导入libmysqlclient.18.dylib.

然后我尝试了:
$ pip install -U MySQL-python …

我下载并按照MySQL 5.5.8(http://dev.mysql.com/downloads/mysql/)和MySQLdb python插件的安装说明进行操作.(http://sourceforge.net/projects/mysql-python/)

当我尝试将MySQLdb导入python终端时,我收到以下错误:

我试图在具有以下配置/版本的三个节点的开发 Hadoop 集群上安装和配置 apache Airflow：

Operating System: Red Hat Enterprise Linux Server 7.7\npython 3.7.3\nanaconda 2\nspark 2.45\n\na)sudo yum install gcc gcc-c++ -y\nb)sudo yum install libffi-devel mariadb-devel cyrus-sasl-devel -y\nc)pip install \'apache-airflow[all]\'\nd)airflow initdb  -- airflow.cfgfile was created with SQLlite\n

然后我按照下面的命令集使用 mysql 配置它

a) rpm -Uvh\xc2\xa0https://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm \nb) sed -i \'s/enabled=1/enabled=0/\' /etc/yum.repos.d/mysql-community.repo \nc) yum --enablerepo=mysql80-community install mysql-community-server \nd) systemctl start mysqld.service\n

我的设置:

• Mac OS 10.6.6 - x86_64
• MySQL 5.5.8
• Python 2.7.1
• Django 1.2.5
• 通过easy_install安装mysql-python

我的情况:

我一直在努力让我的设置工作.问题出在mysql-python接口上.最初,我遇到了类似的问题(对于我正在使用的Django)在python中执行import语句:

import MySQLdb

但我读到了这个问题/解决方案,证明它在修复方面是成功的.我安装了django并且它工作得很好但是它遇到了mysql接口的问题.当我点火终端并键入:

>> python manage.py dbshell

生成以下错误:

现在,我不明白为什么在Python中导入模块不会引发错误,但是在django中使用mysql接口.

顺便说一句,我的settings.py看起来像这样:

DATABASES = {
'default': {
    'ENGINE': 'mysql', # Add 'postgresql_psycopg2', 'postgresql', …
