Mac OS X (El Capitan) 上 MySQLdb 的 Python 导入错误

Question

I have installed MySQLdb on El Capitan using:

brew install mysql
pip install MySQL-python

When I try python -c "import MySQLdb" I get the following error:

  File "<string>", line 1, in <module>
  File "MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(./_mysql.so, 2): Library not loaded: libssl.1.0.0.dylib
  Referenced from: /Users/<user>/anaconda/lib/python2.7/site-packages/_mysql.so
  Reason: no suitable image found.  Did find:
    /usr/local/bin/mysql/lib/libssl.1.0.0.dylib: stat() failed with errno=20

Found some related posts but still did not figure out how to fix this. Any help is much appreciated.

EDIT: If I decide to revert step 1 ( brew uninstall mysql ) because SQLite (sqlite3) comes pre-installed with El Capitan, I get the following error message:

  File "<string>", line 1, in <module>
  File "/Users/<user>/anaconda/lib/python2.7/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/Users/<user>/anaconda/lib/python2.7/site-packages/_mysql.so, 2): Library not loaded: /usr/local/opt/mysql/lib/libmysqlclient.20.dylib
  Referenced from: /Users/<user>/anaconda/lib/python2.7/site-packages/_mysql.so
  Reason: image not found 

What am I missing? Are the two error messages related?

Answer 1

I got an error like this after, I assume, homebrew updated mysql. By running pip uninstall mysqlclient && pip install mysqlclient I got things working again without having to set DYLD_LIBRARY_PATH .
