在mac上安装MySQL python

我正在使用OSX 10.8和PyCharm进行Python开发项目。我已经使用网站上的说明为mac安装了MySQL python

但是，运行项目时会出现以下错误：

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows
  Referenced from: /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so
  Expected in: flat namespace
 in /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so

错误中提到的文件存在于位置-/Users/ashishagarwal/.python-eggs/MySQL\u python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp//u MySQL.so

整个错误消息是-

您应该首先通过安装MySQL，以使python MySQL在OS X上正常工作

pip uninstall MySQL-python
brew install mysql
pip install MySQL-python

---

确保你有最新版本的Xcode，包括命令行工具。我只是从应用商店下载了2GB更新。我有一个类似的问题，特别是，这修复了它

---

干杯！

如果您使用python，如：

import mysql.connector

---

您必须首先下载mysql连接器这里是链接

我很久以前用homebrew安装了mysql，所以当我升级OSX后遇到问题时，我用

brew重新安装再次安装了它mysql@5.7

（我运行了5.7.10）并重新安装了MySQL-python，我希望它能够得到解决。得到了上面提到的错误

它真的帮了我的忙，花了几个小时之后，我不知道该做什么，从源代码和所有东西重建。我尝试了其他用于mysql的python应用程序，但都是一样的

---

我不知怎的意识到MySQL python构建的客户端版本不对，所以我检查了

/usr/local/opt/MySQL

链接的位置，它就链接到了我7年前通过dmg安装的以前的版本！一旦我删除了该链接，然后运行

brew link MySQL

，然后运行created安装了一个新的virtualenv并从头开始安装了所有的软件包。它终于成功了！

你能给出原因吗？这个软件包是从源代码编译的，需要mysql开发头。当你用自制软件安装

mysql

软件包时，这些软件包也会被安装。你不知道需要多少时间
