Django 在 Windows Server 上使用 mod_wsgi。没有名为“lxml.etree”的模块答案

【问题标题】：Django on Windows Server using mod_wsgi. No module named 'lxml.etree'Django 在 Windows Server 上使用 mod_wsgi。没有名为“lxml.etree”的模块
【发布时间】：2020-06-09 18:33:22
【问题描述】：

我正在通过 Apache 将一个新的 Django 项目部署到本地 Windows 服务器，其中包含两个预先存在的 Django 项目。该站点在服务器上本地运行时可以工作，但不能通过 WSGI 运行。我正在使用 mailmerge 包来操作一些 docx 模板，当网站加载时，它在“来自 lxml.etree 导入元素”这一行上失败。

我已经尝试修改mailmerge.py文件中的导入命令无济于事。我已经在我的 virtualenv 内外安装了 lxml 和 mailmerge 包。我已经用谷歌搜索过这个网站和其他网站，但是当我尝试各种修复操作时，搜索结果要么不适用，要么没有解决问题。

这是我的项目 Apache 错误日志中的 sn-p：

Apache Error Log

这是我的 wsgi_windows.py 文件：

# execfile(activate_this, dict(__file__=activate_this))
exec(open(activate_this).read(),dict(__file__=activate_this))

import os
import sys
import site

# Add the site-packages of the chosen virtualenv to work with
site.addsitedir('D:/QR/qr_env/Lib/site-packages')




# Add the app's directory to the PYTHONPATH
sys.path.insert(0,'D:/QR')
sys.path.insert(1,'D:/QR/quality_review')

os.environ['DJANGO_SETTINGS_MODULE'] = 'quality_review.settings'
#os.environ.setdefault("DJANGO_SETTINGS_MODULE", "quality_review.settings")
os.environ["DJANGO_SETTINGS_MODULE"] = "quality_review.settings"

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application

这是项目在 vhosts.conf 文件中的条目：

我不确定还需要哪些其他信息来提供帮助，但如果需要，我很乐意提供其他文件。

【问题讨论】：

请分享您的 apache.conf LoadFile "***ython37.dll" 和 LoadModule wsgi_module "***\mod_wsgi.cp37-win_amd64.pyd" 中的相似行
我已使用请求的信息编辑了我的帖子。感谢您的回复。
你的windows系统是32位的？
不，它是 64 位 Windows。
你已经安装了32位版本的python37：/mod_wsgi.cp37-win32.pyd"

标签： python django apache mod-wsgi

【解决方案1】：

请卸载 32bits python37 版本并重新安装 64bits python37 版本并更新您的 apache conf：

LoadFile "***/python37.dll"
LoadModule wsgi_module "*****/mod_wsgi.cp37-win_amd64.pyd"

然后如果有任何错误，请分享所有的apache日志文件

请在您的 httpd.conf 文件中：设置：

LogLevel debug

看看你的日志文件，你能找到这些信息吗：

对于 WSGIPythonHome：

“用于在 Python 初始化时向 Python 指示其库文件的安装位置。”

我认为您的项目站点包位于：

【讨论】：

我已将 32 位 python 和 Apache 替换为 64 位。我原来的两个站点在配置 Apache 后工作，但最新站点仍然给出相同的模块未找到错误。这是错误日志：link
抱歉，您指的是什么路径？
我在日志中没有找到apache启动的消息
httpd.conf 的路径：
Apache 正在启动，并成功地为其他站点提供服务。它只是无法加载有问题的网站。 httpd.conf 中的路径是我从 mod_wsgi 得到的路径，所以我相信它们是正确的。
