我试图在Dreamhost共享服务器上运行一个Flaskhello world应用程序，遵循他们的wiki ，但我没有任何运气。
我的Flask应用程序是来自
> from flask import Flask app = Flask（__ name__） @ app.route（'/'） def hello_world（）： return'Hello World！ ' if __name__ =='__main__'： app.run（） 根据DH wiki的说明，我在一个名为mysite的文件夹中有一个名为hello.py的文件。我的passenger_wsgi.py文件是：
import sys，os INTERP = os.path.join（os.environ如果sys.exe可用！= INTERP： os.execl（INTERP，INTERP，* sys.argv） $'$'$'$' b sys.path.append（os.getcwd（））$ b $ mysite从应用程序导入hello <我已经尝试在Python控制台中运行这些命令，并且最后一次导入行失败，直到我将 __ init __。py 文件添加到mysite目录。 b $ b
当我尝试访问网站时，我得到了一个500错误（不幸的是，在日志中没有任何东西，除非它们在日志中，我无法得到，因为这是一个共享服务器。 ..）。
由于这是最基本的设置（即从wiki复制和粘贴），我不禁感到，我失去了一些东西真的很简单。或者也许这是不可能在共享服务器上？
解决方案回答我自己的问题意味着我正在跟自己说话吗？
无论如何 - 我似乎已经修好了。而不是找到一个很好的有用的错误消息，我一次又一次地经历了所有的步骤，事实证明这是 passenger_wsgi.py 文件中的导入错误。由于该应用程序位于 mysite 子目录中，因此：
来自mysite import hello as application 应该已经（实际上现在是）：
from mysite.hello导入应用程序作为应用程序 它的工作原理。这很好。
I'm trying to get a Flask "hello world" application working on a Dreamhost shared server, following the instructions on their wiki, but I'm not having any luck.
My Flask application is the "hello world" one from the Flask quickstart guide:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
Which I've got in a file called "hello.py" in a folder called mysite, as per the DH wiki instructions. My passenger_wsgi.py file is:
import sys, os
INTERP = os.path.join(os.environ['HOME'], 'flask_env', 'bin', 'python')
if sys.executable != INTERP:
os.execl(INTERP, INTERP, *sys.argv)
sys.path.append(os.getcwd())
from mysite import hello as application
I've tried running the commands in a Python console, and last import line failed until I added the __init__.py file to the mysite directory.
When I try and access the website I just get a 500 error (and nothing in the logs unfortunately, unless they're in logs I can't get to as this is a shared server...).
As this is the most basic of setups (i.e., copied and pasted from a wiki), I can't help feeling that I'm missing something really simple. Or perhaps this isn't possible on a shared server?
解决方案 Does answering my own question mean I'm talking to myself?
Anyway - I seem to have fixed it. Rather than find a nice helpful error message, I went through all the steps again one at a time, and it turns out it was an import error in the passenger_wsgi.py file. As the app is in the mysite subdirectory, the line:
from mysite import hello as application
should have been (and in fact, now is):
from mysite.hello import app as application
And it works. Which is nice.
