我是运行网站的初学者，但我有一个 GoDaddy VPS 和域名，我正在尝试在其上运行 Flask 网站。此 Flask 网站使用 Playwright 从网页中抓取数据，并将其发送到通过 HTTPS 运行的 Flask 应用程序。但是，当我尝试运行
p = sync_playwright().start()我检查了所有路径，它们似乎是正确的，main.py 和其他文件由 www-data 用户拥有。我的 mod_wsgi 文件如下：
#!/usr/bin/python
import sys
sys.path.insert(0,"/var/www/jimmyscompany.top")
from main import app as application
我的 apache2 站点启用文件是：
<IfModule mod_ssl.c>
<VirtualHost *:443>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
ServerName www.jimmyscompany.top
ServerAdmin myemail.com
DocumentRoot /var/www/jimmyscompany.top
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.

#LogLevel info ssl:warn

# For most configuration files from conf-available/, which are

我已经检查过，所有路径都是正确且有效的。相关的错误日志是：（来自/var/log/apache2/error.log）

总结一下：当我尝试启动 playwright 时，我从 mod_wsgi 收到错误。如果您需要更多代码信息，请询问！
我目前也遇到同样的问题。
你找到解决办法了吗？
谢谢
