记录第一次在宝塔部署Flask框架遇到的坑

最后在简书找到相关解决方案

报错内容如下

Python项目管理器启动Flask项目 报错ModuleNotFoundError: No module named ‘json’

其实并不是没有json模块，而是因为启动配置文件的权限问题，导致没有模块，只需要将配置文件的权限修改：

bind = '0.0.0.0:40000'
user = 'root' # 将www改为root重启即可
workers = 1
threads = 2
backlog = 512
daemon = True
chdir = '/root/gobes.client/'
access_log_format = '%(t)s %(p)s %(h)s "%(r)s" %(s)s %(L)s %(b)s %(f)s" "%(a)s"'
loglevel = 'info'
worker_class = 'geventwebsocket.gunicorn.workers.GeventWebSocketWorker'
errorlog = chdir + '/logs/error.log'
accesslog = chdir + '/logs/access.log'
pidfile = chdir + '/logs/client.pid'
