我有一个运行全新安装的Ubuntu 10.04 LTS的VPS。我正在尝试使用Flask微框架设置一个实时应用程序,但它给了我麻烦。当我试图让它运行时我记笔记,这是我的逐个播放,以确定我错误的位置。

为我服务器500服务器错误页面。这是最新的错误日志:
mod_wsgi (pid=3514): Target WSGI script '/home/myapp/www/myapp.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=3514): Exception occurred processing WSGI script '/home/myapp/www/myapp.wsgi'.
Traceback (most recent call last):
File "/home/myapp/www/myapp.wsgi", line 4, in <module>
from myapp import app as application
ImportError: No module named myapp
这些错误暗示这是非常明显的,但我很遗憾。

显然,它无法找到您的“myapp
”包。您应该将其添加到myapp.wsgi
文件中的路径,如下所示:
import sys
sys.path.append(DIRECTORY_WHERE_YOUR_PACKAGE_IS_LOCATED)
from myapp import app
此外,如果myapp
模块是一个包,则应将__init__.py
文件放入其目录中。

修改专栏sys.path.append
,它必须是一个字符串。
import sys
sys.path.append('directory/where/package/is/located')
注意单引号。
