在OS X中使用PyDev和外部库进行故障

Question

我已经在OS X 10.6.3下的Eclipse(3.5.1)中成功安装了最新版本的PyDev,使用python 2.6.1
我在安装我已安装的库时遇到了麻烦.
例如,我正在尝试使用cx_Oracle库,如果从使用某些文本编辑器创建的简单脚本的python interpeter调用,则该库非常有效.
但我不能让它在Eclipse中运行:我有一小段代码:

import cx_Oracle
conn = cx_Oracle.connect(CONN_STRING)
sql = "select field from mytable"
cursor = conn.cursor()
cursor.execute(sql)
for row in cursor:
    field = row[0]
    print field

如果我从Eclipse执行它,我会收到以下错误:

import cx_Oracle
  File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 7, in <module>
  File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so, 2): Library not loaded: /b/227/rdbms/lib/libclntsh.dylib.10.1
  Referenced from: /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so
  Reason: no suitable image found.  Did find:
    /Users/dave/lib/libclntsh.dylib.10.1: mach-o, but wrong architecture

相同的代码段完全可以从python shell中运行

我在偏好中配置了Eclipse中的interpeter - > PyDev - > Interpreter - Python,使用Auto Config选项并选择找到的所有lib.

我在这做错了什么？

编辑:启动

file /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so

从命令行告诉:

/Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so: Mach-O universal binary with 3 architectures

Answer 1

在eclipse中,在'PyDev',Interpreter - Python(或者你正在使用的)下设置以下'环境变量'.

1. ORACLE_HOME = [您的安装路径]/instantclient_10_2
2. LD_LIBRARY_PATH = $ ORACLE_HOME
3. DYLD_LIBRARY_PATH = $ ORACLE_HOME

它对我有用.
