如何解析“报告”报告。自定义“已存在！”启动OpenERP 7.0时出错

运行Ubuntu12.04，我尝试运行OpenERP7.0，使用最新的tarball存档

wget "http://nightly.openerp.com/7.0/nightly/src/openerp-7.0-latest.tar.gz"
tar -xzf openerp-7.0-latest.tar.gz
# cd extracted directory
./openerp-server  —xmlrpc-port=40069 —netrpc-port=40070 —addons-path=openerp/addons,openerp/web/addons

以下是我得到的：

Traceback (most recent call last):

我已经在同一台机器上成功运行了一个6.0实例，但在我尝试启动7.0版本时，该服务器没有运行。我不知道这是否与我之前已经安装了6.0有关。这可能是PostgreSQL的问题吗？我没有删除现有的6.0数据库。

在没有更多参数的情况下运行服务器似乎是可行的：

./openerp-server
2014-01-13 14:26:35,270 1014 INFO ? openerp: OpenERP version 7.0-20140113-001013

您只是在避免使用插件，因为插件隐藏了bug。这不是修好的。
