Question

经过很多小时，我仍然无法获得用于运行Django项目的虚拟环境。

我的Django项目在本地工作（使用runserver，没有apache，使用python 2.7和venv）。以前，它在具有Apache但没有venv和默认python版本2.7的开发服务器上也可以正常工作。

现在，我正在尝试使用使用python 3.7的虚拟环境。

步骤1：

我用python 3.7创建了一个虚拟环境：

sudo virtualenv -p /usr/bin/python3.7 /var/www/abcd.com/venvs/venv_core
cd /var/www/abcd.com/venvs/venv_core/bin
source activate
sudo ./pip install --upgrade pip
cd ../../../
sudo venvs/venv_core/bin/pip install -r requirements.txt

（---- system-site-packages默认关闭）

Ubuntu 18.04.1。已包含python版本3.7。所以我用了。（在之前尝试自己编译python 3.7时，我完全迷失了，不得不回滚到虚拟机的先前快照。）

系统：

Ubuntu 18.04.1 LTS "bionic"
included Python versions: 2.7.15rc1 (sys default), 3.6.5 (sys default), 3.7.0b3
Apache/2.4.29 (Ubuntu)

https://docs.python.org/3/library/venv.html https://virtualenv.pypa.io/en/stable/reference/

这个venv似乎是正确创建的。

我还修改了wsgi配置（见下文）。

http://modwsgi.readthedocs.io/en/develop/user-guides/installation-issues.html#

但是当我重新启动apache时，我得到了错误：

ImportError: No module named site

https://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html#virtual-environment-and-python-version

Django Apache and Virtualenv ImportError: No module named site

https://serverfault.com/questions/285229/python-django-wsgi-apache-importerror-no-module-named-site

似乎我必须使用python 3.7.0编译mod_wsgi。

步骤2：

然后我尝试使用python 3.7编译mod_wsgi：

sudo apt-get remove libapache2-mod-wsgi
sudo apt-get build-dep libapache2-mod-wsgi
sudo mkdir /tmp/wsgi
cd /tmp/wsgi
sudo apt-get source libapache2-mod-wsgi
cd mod-wsgi-4.5.17
sudo dpkg-buildpackage -rfakeroot -b
sudo dpkg -i /tmp/wsgi/libapache2-mod-wsgi-py3_4.5.17-1_amd64.deb

我收到以下错误（下面的详细日志）：

Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

mod_wsgi is compiled in one version and running in a different version even after following the given steps

https://bugs.launchpad.net/ubuntu/+source/libapache2-mod-python/+bug/1073147/comments/8

Django / Apache / mod_wsgi: No module named importlib

https://code.google.com/archive/p/modwsgi/wikis/CheckingYourInstallation.wiki#Python_Installation_In_Use

最后，我不知道该如何做才能使系统正常运行。我对Linux不太了解，而且我不是Python专家。

1）我必须为python 3.7编译mod_wsgi还是有更简单的方法？

2）我是否正确编译了mod_wsgi？如果没有，我该怎么办？

3）是否已正确配置dev.conf？如果没有，我该怎么更改？

请问有人可以帮我吗？

dev.conf（Apache配置：etc / apache2 / sites-available / dev.conf）：

Define server_name abcde.com
WSGIPythonHome /var/www/${server_name}/venvs/venv_core/lib/python3.7/
...
<IfModule mod_ssl.c>
    WSGIDaemonProcess ${server_name} processes=2 threads=15 display-name=%{GROUP} python-path=/var/www/${server_name}:/var/www/${server_name}/venvs/venv_core/lib/python3.7:/var/www/${server_name}/venvs/venv_core/lib/python3.7/site_packages
    WSGIProcessGroup ${server_name}
    WSGIScriptAlias / /var/www/${server_name}/index.wsgi
...

index.wsgi：

import os
import time
import traceback
import signal
import sys
from django.core.wsgi import get_wsgi_application

sys.path.append('/var/www/abcde.com/')
sys.path.append('/var/www/abcde.com/abcde')
os.environ['DJANGO_SETTINGS_MODULE'] = 'abcde.settings'

try:
    application = get_wsgi_application()
except Exception:
    print 'handling WSGI exception'
    # Error loading applications
    if 'mod_wsgi' in sys.modules:
        traceback.print_exc()
        os.kill(os.getpid(), signal.SIGINT)
        time.sleep(2.5)

error.log：

带有python 3.7和Apache的Python虚拟环境：是否必须编译mod_wsgi？
