[英]Error loading MySQLdb module with Django on OS X
我有一个非常奇怪的情况,我不知道怎么了。
我正在开发Django项目,我:
在OS X上安装MySQL
添加了DATABASES值:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}
但是随后Django / Mezzanine告诉我,加载MySQLdb模块时出错。
因此,我用Google搜索了有关此问题的一些技巧,并尝试了以下方法:
pip install mysql-python
现在我被卡住了。 出现相同的错误,感觉MySQL连接器/适配器有问题,无法加载它。
接下来我应该尝试什么?

当您尝试为postgres安装psycopg2软件包时,问题是相同的。 为了解决这个问题,您必须将mysql bin目录添加到PATH中 。
请按照以下步骤操作:
1.下载DMG存档并安装Mysql Community服务器的最新正式版本: mysql-5.7.9
2.将mysql bin目录添加到PATH。 为此,将以下内容添加到您的~/.bash_profile
文件中
# add mysql bin directory
PATH="/usr/local/mysql/bin/:${PATH}"
export PATH
pip install mysql-python
它应该输出:已Successfully installed mysql-python-1.2.5
对于Mac用户
mysql-connector-c有一些问题,
打开/ usr / local / bin / mysql_config脚本进行修改:
Libs = "-L$pkglibdir"
Libs = "$libs -l"
变成:
Libs = "-L$pkglibdir"
Libs = "$libs -lmysqlclient -lssl -lcrypto"
然后安装Python-Mysql,
pip install MySQL-python
