在OS X上使用Django加載MySQLdb模塊時出錯

我有一個非常奇怪的情況，我無法弄清楚什麼是錯的。在OS X上使用Django加載MySQLdb模塊時出錯

我正在一個Django項目和我：

在OS X

新增裝機容量的MySQL數據庫值：

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.mysql', 
     'OPTIONS': { 
      'read_default_file': '/path/to/my.cnf', 
     }, 
    } 
}

但隨後的Django /夾層告訴我有一個錯誤加載MySQLdb模塊。

所以我用Google搜索了一些解決這個技巧和嘗試這些方法：

pip install mysql-python

重新安裝PIP
下載ez_setup.py並安裝

現在我被困。同樣的錯誤顯示出來，感覺就像MySQL連接器/適配器有問題，無法加載。

接下來我應該嘗試什麼？

當運行PIP命令：

The directory '/Users/myusername/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. 
You are using pip version 7.0.3, however version 7.1.2 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command.

你能提供錯誤的完整追溯嗎？ –

究竟是什麼時候你運行pip命令？你是否和你的項目在同一個virtualenv中做到這一點？ –

@DanielRoseman：現在編輯輸出。 – lol5433

的問題是一樣的，當你要安裝psycopg2包Postgres的。爲了解決這個問題，你必須添加到你的mysql bin目錄下的PATH。

按照此步驟：
1.下載DMG歸檔並安裝MySQL社區服務器的最新正式版：mysql-5.7.9
2.添加MySQL bin目錄的路徑。要做到這一點，添加到您的~/.bash_profile文件這個

# add mysql bin directory 
PATH="/usr/local/mysql/bin/:${PATH}" 
export PATH

重新啓動計算機

運行：pip install mysql-python

，它應該輸出：Successfully installed mysql-python-1.2.5

謝謝你太多了！這是一個很好的工作答案！ – lol5433

你的歡迎:)如果以後，你正在使用postgres，做同樣的事情。 –
