Question

我试图在Ubuntu机器上运行web2py。所有文档似乎都表明要在* nix系统上运行它，你下载源代码并执行：

python web2py.py

我抓住了source（稳定来源，而不是主干，版本1.99.4）并尝试了上述内容，但输入了服务器的密码后我（在终端中）：

$ python web2py.py

然后在浏览器中我得到：

Internal error
Ticket issued: welcome/127.0.0.1.2012-.....[abbreviated]

有什么建议吗？我正在运行Python 2.7.1+。我在其他地方读到你还需要为web2py安装pyschopg2才能运行，我已经确认这实际安装了（我做了sudo apt-get install python-psycopg2并得到了“python-psycopg2已经是最新版本”了）。

Answer 1

我刚下载并且web2py在ubuntu，python 2.7.2 +

中运行正常

bruce @ vaiubuntu：〜/ Downloads / web2py $ python web2py.py

您是否尝试在appengine环境中运行web2py？

你的Python中SQLITE模块是否正常工作？

可能是权限问题，您的用户是否有权写入web2py / *文件夹？

Answer 2

它看起来像web2py 1.99.4中的错误。使用Postgres和psycopg2我遇到了同样的问题，但是在Windows中。

我尝试使用1.99.2并且工作正常。

实际上，这个bug似乎与神秘的错误消息有关 - 1.99.2给了我一个错误信息，即数据库不存在，这很容易修复。 1.99.4没有提到丢失的数据库。但是，当我创建数据库并尝试使用1.99.4时，它工作正常。

为什么启动时web2py会崩溃？
