我刚刚完成安装mod_wsgi,但是我在启动Pyramid应用程序时遇到了问题。
我在CentOS 5.8上使用python 2.7,Apache 2.2.3,mod_wsgi 3.4
这是我的httpd.config文件
WSGISocketPrefix run/wsgi
<VirtualHost *:80>
ServerName myapp.domain.com
ServerAlias myapp
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess pyramid user=apache group=apache processes=1 threads=4 \
python-path=/var/wsgi_sites/site-packages
WSGIScriptAlias / /var/wsgi_sites/myapp/apache.wsgi
<Directory /var/wsgi_sites/myapp>
WSGIProcessGroup pyramid
Order allow,deny
Allow from all
</Directory>
LogLevel debug
ErrorLog /var/log/httpd/myapp_error
</VirtualHost>
我已经给了Apache所有的site-package,python-eggs和myapp文件夹。
我用来创建WSGI应用程序的模块appache.wsgi包含以下代码
import os
os.environ['PYTHON_EGG_CACHE'] = '/var/wsgi_sites/python-eggs'
from pyramid.paster import get_app
application = get_app('/var/wsgi_sites/myapp/development.ini','main')
当我重新启动Apache并尝试访问应用程序时,我收到以下错误
mod_wsgi (pid=14842, process='pyramid', application=''): Loading WSGI script '/var/wsgi_sites/myapp/apache.wsgi'.
mod_wsgi (pid=14842): Target WSGI script '/var/wsgi_sites/myapp/apache.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=14842): Exception occurred processing WSGI script '/var/wsgi_sites/myapp/apache.wsgi'.
Traceback (most recent call last):

我尝试查看request.py文件,但没有语法错误。
答案 0 :(得分:5)
通常当你遇到语法错误时,前一行就是罪魁祸首。看the Pyramid source,我们看到前一行是:
@implementer(IRequest)
这是一个类装饰器。在2.6版本中,类装饰器被添加到Python中。 CentOS 5.8上的默认Python版本是2.4。
您的解决方案是: 1.使用具有更新版本的Python的操作系统,或者 2.确保您的Pyramid应用程序使用2.7版。这涉及安装Python 2.7 以及系统的默认Python安装,该安装由其他应用程序使用,必须保持不变。
如果您选择安装2.7,您将执行以下操作:
$ wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 $ tar xf Python-2.7.3.tar.bz2 $ cd Python-2.7.3 $ ./configure --prefix=/usr/local $ make && make altinstall
答案 1 :(得分:0)
我看到错误中提到了两个不同的wsgi文件
/var/wsgi_sites/project_name_api/apache.wsgi
和
/var/wsgi_sites/myapp/apache.wsgi
我在您粘贴的httpd.conf中看不到任何project_name路径引用。
