我正在尝试让我的 API 使用 Apache 在我的 Ubuntu VPS 上工作，这是我的 FLASK 代码；

它抛出；

我不明白为什么会发生这种情况，因为它在我的本地计算机上完美运行，但如果我尝试从 VPS 运行它，它只会抛出错误 500。
我在网上搜索过，但似乎找不到解决方案。
非常感谢所有帮助。

这是错误；

我说;从 FlaskApi 导入应用程序
但是wsgi和init文件在同一个地方，是这个问题吗>>？
最佳答案
看起来您确实在尝试从 FlaskApi 导入应用程序，但您已经在其中了。
您可以尝试将脚本的第 6 行更改为:
from . import app as application
或者
import app as application
为了更快地测试(并避免一直重启服务器)，您也可以尝试运行:
python /var/www/FlaskApi/api.wsgi
