Odoo的App List中无法找到创建的自定义模块进行安装

Question

配置文件如下：
jun@jun-VirtualBox:/etc/odoo$ cat openerp-server.conf
[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = 127.0.0.1
db_port = 5432
db_user = odoo
db_password = 123
addons_path = /usr/lib/python2.7/dist-packages/openerp/addons,addnos
;addons_path =addons,myaddons
Odoo的App List中无法找到创建的自定义模块进行安装,请问可能原因是什么？
