无法执行 Python 脚本文件“/home/dev/project/project/wsgi.py”。处理 WSGI 脚本“/home/dev/project/project/wsgi.py”时发生异常

Question

我正尝试在 Hostinger 提供的 VPS 上托管我的 django 网站。服务器运行ning Ubuntu 20.04 64 位。我通过运行ning 命令在没有 apache2 的情况下将网站设置为运行 python manage.py runserver
设置 apache2 服务器后，出现 500 内部服务器错误。我检查了错误日志，它显示了这个

该错误表明您要在此处加载的 JSON 文件：

with open("/etc/config.json") as config_file:
    config = json.load(config_file)

不正确 JSON 因为在 JSON 文件的第 4 行引用错误（您可能使用单引号而不是双引号）：

JSONDecodeError: Expecting property name enclosed in double quotes: line 4 column 1 (char 71)
