为什么 web2py 在启动时会崩溃? [英] Why does web2py crash for me upon startup?

问题描述

我正在尝试让 web2py 在 Ubuntu 机器上运行.所有文档似乎都表明要在 *nix 系统上运行它，您下载源代码并执行:

I"m trying to get web2py running on an Ubuntu machine. All the docs seem to indicate that to run it on a *nix system, you download the source and do:

python web2py.py

python web2py.py

我获取了 源(稳定源，不是主干，版本 1.99.4) 并尝试了上述操作，但是在输入服务器密码后我得到了(在终端中):

I grabbed the source (stable source, not the trunk, version 1.99.4) and tried the above, but after entering a password for the server I get (in the terminal):

然后在浏览器中我得到:

And then in the browser I get:

有什么建议吗?我正在运行 Python 2.7.1+.我在别处读到你还需要为 web2py 安装 pyschopg2 才能运行，我已经确认这实际上也已安装(我做了一个 sudo apt-get install python-psycopg2 并得到python-psycopg2 已经是最新版本了").

Any suggestions? I'm running Python 2.7.1+. I've read elsewhere that you also need pyschopg2 installed for web2py to run, and I've confirmed that this is in fact installed as well (I did a sudo apt-get install python-psycopg2 and got "python-psycopg2 is already the newest version").

推荐答案

我刚下载，web2py 在 ubuntu、python 2.7.2+ 中运行正常

I just downloaded and web2py runs ok in ubuntu, python 2.7.2+

您是否尝试在 appengine 环境中运行 web2py?

Are you trying to run web2py on appengine environment?

你的 Python 中有 SQLITE 模块吗?

Do you have SQLITE module working ok in your Python?

可能是权限问题，你的用户有权限写入 web2py/* 文件夹吗?

A possibility is permission issue, your user have permission to write to web2py/* folder?
