python - pgAdmin4 安装 - 目标 WSGI 脚本无法作为 Python 模块加载

问题描述

这个问题之前已经在这里问过，但该解决方案对我不起作用。我的 python venv 配置不能很好地与 apache2 mod_wsgi 配合使用，我无法从根本上解决这个问题。目前，我无法对这个问题发表评论，所以我正在发布另一个问题

以下是尝试登录网站时的 apache2 错误日志。

这是虚拟主机配置：

<VirtualHost *>
    ServerName shinyapp01t

    WSGIDaemonProcess pgadmin processes=1 threads=25 python-home=/home/awashburn/anaconda3/envs/pgadmin4 display-name=pgadmin4
    WSGIScriptAlias /pgadmin /home/awashburn/anaconda3/envs/pgadmin4/lib/python3.7/site-packages/pgadmin4/pgAdmin4.wsgi

    <Directory "/home/awashburn/anaconda3/envs/pgadmin4/lib/python3.7/site-packages/pgadmin4/">
        WSGIProcessGroup pgadmin
        WSGIApplicationGroup %{GLOBAL}
        Require all granted
    </Directory>
</VirtualHost>

我参考了 DigitalOcean 的这些说明，试图在 Ubuntu 16.04 上安装 pgAdmin4。

编辑：我使用了 python3 venv 而不是 anaconda 虚拟环境，一切正常。所以根本原因是anaconda系统。在 mod_wsgi 邮件列表上有一个关于这个的讨论
