Python mod_wsgi、apache和sqlalchemy的语法类模板(元类=_TemplateMetaclass)无效
我有一个脚本,可以在其中导入:Python mod_wsgi、apache和sqlalchemy的语法类模板(元类=_TemplateMetaclass)无效,python,apache,sqlalchemy,mod-wsgi,bottle,Python,Apache,Sqlalchemy,Mod Wsgi,Bottle,我有一个脚本,可以在其中导入: from bottle import route, request from sqlalchemy import create_engine, MetaData from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import sessionmaker from sqlalchemy import Table, Column, Integer import xml.
from bottle import route, request
from sqlalchemy import create_engine, MetaData
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
from sqlalchemy import Table, Column, Integer
import xml.etree.cElementTree as ET
@route('/getmember')
def get_member():
pass
run(host='localhost', port=8080, reloader=True)
我可以使用瓶子内置web服务器成功运行此脚本:$python3.2 getmember.py
完成后,我想使用Apache和mod_wsgi
运行应用程序,并创建一个名为adapter.wsgi
的脚本:
import sys, os, bottle
sys.path = ['/var/www/getmember/'] + sys.path
os.chdir(os.path.dirname(__file__))
import getmember
application = bottle.default_app()
在Apache中,我有:
WSGIDaemonProcess getmember user=www-data group=www-data processes=1 threads=5 python-path=/usr/lib/python3.2/site-packages
WSGIScriptAlias /getmember /var/www/idcheck/adapter.wsgi
<Directory /var/www/getmember>
WSGIProcessGroup getmember
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
那么,为什么它在正常的python调用下工作(意味着所有库和包都正常),而在wsgi和Apache下却抛出了这个错误呢?我感觉它找不到该包的所需路径,但不确定如何添加它
编辑
我运行了import sys
和print sys.path
,以获取运行python3.2环境时加载的所有路径。我在Apache中添加了多个路径到Python路径:
WSGIDaemonProcess idcheck user=www-data group=www-data processes=1 threads=5 python-path=/usr/local/lib/python3.2/dist-packages/distribute-0.6.34-py3.2.egg:/usr/local/lib/python3.2/dist-packages/logilab_common-0.58.3-py3.2.egg:/usr/local/lib/python3.2/dist-packages/logilab_astng-0.24.1-py3.2.egg:/usr/local/lib/python3.2/dist-packages/SQLAlchemy-0.8.0b2-py3.2.egg:/usr/local/lib/python3.2/dist-packages/psycopg2-2.4.6-py3.2-linux-x86_64.egg:/usr/local/lib/python3.2/dist-packages/pip-1.2.1-py3.2.egg:/usr/local/lib/python3.2/dist-packages/sqlautocode-0.6b1-py3.2.egg:/usr/lib/python3.2:/usr/lib/python3.2/plat-linux2:/usr/lib/python3.2/lib-dynload:/usr/local/lib/python3.2/dist-packages:/usr/lib/python3/dist-packages
这样,前面的错误消失了,我得到了一个新的无效语法。SQLAlchemy和mod_wsgi+Apache有什么问题吗

也许Apache使用的是2版Python可执行文件?您可以检查apache用户的搜索路径,或者查看WSGI指令WSGIPythonHome/WSGIPythonExecutable
尝试:
-剪断-
@route('/test', method='GET')
def test():
return sys.version
或:
我认为它使用的是Python3.2,因为我在apache2.conf中有这样一个条目:
WSGIDaemonProcess idcheck user=www数据组=www数据进程=1线程=5 python路径=/usr/lib/Python3.2/site packages
?另外,在我插入该行之前,它找不到瓶子
包装。现在确实如此,但现在在SQLAlchemy部分失败了
import sys
@route('/test', method='GET')
def test():
return sys.version
#grep Python /var/log/httpd/error_log
