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

分类：编程问答

如何解决无法执行 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

我正在尝试在 Hostinger 提供的 VPS 上托管我的 django 网站。服务器在 Ubuntu 20.04 64 位上运行。我通过运行命令让网站在没有 apache2 的情况下运行 Process 1: Consuming events from Kafka and put in staging table. Process 2: Reading staging table (configurable rows),execute business rules,apply consumer database changes & update the status of processed records in staging table. (we may have multiple process to do this step)
设置 apache2 服务器后，我收到 500 内部服务器错误。 我检查了错误日志，它显示了这一点

•   We are missing the advantage of offset handling provided by Kafka and we are doing manual update of processed records in staging table.
•   Locking & Blocking on staging tables for multi instance,as we are trying to insert & do updates after processing in the same staging table 
    (note: I can design separate tables and move this data there and process them but that could is introducing multiple processes again.

这是我的 apache2 配置文件
`` 
python manage.py runserver
``
这是我的 settings.py 文件

解决方法

错误表明您尝试在此处加载 JSON 文件：

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

不是正确的 JSON，因为在 JSON 文件的第 4 行中引用错误（您可能使用单引号而不是双引号）：

JSONDecodeError：需要用双引号括起来的属性名称： 第 4 行第 1 列（字符 71）
