virtualenv pip mysqldb mac os X python

Question

我嘗試了這個http://jazstudios.blogspot.com/2010/07/installing-mysql-python-mysqldb-in.html提示在virtualenv（名為dogme ）中安裝mysql-python（ mysqldb ）。 （這篇文章指出了兩件重要的事情：

export ARCHFLAGS="-arch x86_64"
echo "mysql_config = /opt/local/bin/mysql_config5" >> ./dogme/build/MySQL-python/site.cfg

幫助編譯mysqldb）

但是，當之后，我運行python，導入MySQLdb，我得到這個：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/.virtualenvs/dogme/lib/python2.5/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/home/.virtualenvs/dogme/lib/python2.5/site-packages/_mysql.so, 2): Symbol not found: _mysql_affected_rows
  Referenced from: /home/.virtualenvs/dogme/lib/python2.5/site-packages/_mysql.so
  Expected in: flat namespace
 in /home/.virtualenvs/dogme/lib/python2.5/site-packages/_mysql.so

誰都明白什么是錯的？

我遇到了類似的問題，看看我的追溯：

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.6/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/Library/Python/2.6/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.16.dylib
  Referenced from: /Library/Python/2.6/site-packages/_mysql.so
  Reason: image not found

我做的是將這些變量放在我的.bash_profile ：

export DYLD_LIBRARY_PATH="/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH"

當我用Apache運行Python CGI應用程序時，我使用SetEnv指令設置了這個相同的變量：

<Directory "/path/to/app">
    SetEnv DYLD_LIBRARY_PATH /usr/local/mysql/lib/:$DYLD_LIBRARY_PATH
    ...
</Directory>

現在一切正常。
