我正在Ubuntu 18.04上的笔记本电脑上工作，并且想像使用服务器一样尝试使用pgadmin和Apache。我遵循this tutorial并按照指示进行操作，但我使用conda创建的虚拟环境除外：
conda create -n pgadmin python=3.6
对于/etc/apache2/sites-available/pgadmin4.conf中的ServerName，我只是使用了从hostname -I获得的第一个IP W.X.Y.Z地址：
<VirtualHost *>
ServerName W.X.Y.Z
WSGIDaemonProcess pgadmin processes=1 threads=25 python-home=/home/sammy/python_envs/pgadmin
WSGIScriptAlias / /home/sammy/python_envs/pgadmin/lib/python3.6/site-packages/pgadmin4/pgAdmin4.wsgi
<Directory "/home/sammy/python_envs/pgadmin/lib/python3.6/site-packages/pgadmin4/">
WSGIProcessGroup pgadmin
WSGIApplicationGroup %{GLOBAL}
Require all granted
</Directory>
</VirtualHost>
仅使用笔记本电脑，默认的Apache网站就可以在浏览器上的该IP上正常运行，但是，在激活gadmin4网站（sudo a2ensite pgadmin4.conf）后使用相同的IP时，我收到了来自Apache的错误消息：< / p>
内部服务器错误服务器遇到内部错误或 配置错误，无法完成您的请求。
请通过[未提供地址]与服务器管理员联系以 告知他们该错误发生的时间以及您的操作 在此错误之前执行。
有关此错误的更多信息可能在服务器错误中可用 日志。
位于W.X.Y.Z端口80的Apache / 2.4.29（Ubuntu）服务器
Apache检查（apachectl configtest）看起来不错：
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK

还请注意，在没有Apache的情况下“直接”使用pgadmin应用程序时，即简单地将/var/{lib,log}/pgadmin4的所有权从www-data更改为sammy并运行下面的命令，工作正常：
source activate pgadmin
python ~/python_envs/pgadmin/lib/python3.6/site-packages/pgadmin4/pgAdmin4.py
我不是专家，但是Apache conf文件似乎存在一些问题，导致某些python版本冲突。当直接从环境执行并绕过Apache时，这些冲突不会发生。我对如何解决它一无所知，任何帮助将不胜感激。
根据this post的建议，我尝试在虚拟环境中运行pip install mod_wsgi并将mod_wsgi-express module-config的输出复制到Apache conf文件（在我的情况下为LoadModule wsgi_module "/home/sammy/python_envs/pgadmin/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"），但是没有运气，同样的错误。
