依照xuxudodo的方式進行安裝，可是進行到在openerp內更新模塊時，無法找到該模塊，出現錯誤信息如下：OpenERP Server ErrorClient Traceback (most recent call last): File "/var/packages/OpenERP7.x/target/openerp/addons/web/http.py", line 195, in dispatch response["result"] = method(self, **self.params) File "/var/packages/OpenERP7.x/target/openerp/addons/web/controllers/main.py", line 1083, in call_button action = self._call_kw(req, model, method, args, {}) File "/var/packages/OpenERP7.x/target/openerp/addons/web/controllers/main.py", line 1071, in _call_kw return getattr(req.session.model(model), method)(*args, **kwargs) File "/var/packages/OpenERP7.x/target/openerp/addons/web/session.py", line 43, in proxy result = self.proxy.execute_kw(self.session._db, self.session.uid, self.session.password, self.model, method, args, kw) File "/var/packages/OpenERP7.x/target/openerp/addons/web/session.py", line 31, in proxy_method result = self.session.send(self.service_name, method, *args) File "/var/packages/OpenERP7.x/target/openerp/addons/web/session.py", line 104, in send raise xmlrpclib.Fault(openerp.tools.ustr(e), formatted_info)Server Traceback (most recent call last): File "/var/packages/OpenERP7.x/target/openerp/addons/web/session.py", line 90, in send return openerp.netsvc.dispatch_rpc(service_name, method, args) File "/usr/lib/python2.7/site-packages/openerp/netsvc.py", line 295, in dispatch_rpc result = ExportService.getService(service_name).dispatch(method, params) File "/usr/lib/python2.7/site-packages/openerp/service/web_services.py", line 614, in dispatch res = fn(db, uid, *params) File "/usr/lib/python2.7/site-packages/openerp/osv/osv.py", line 188, in execute_kw return self.execute(db, uid, obj, method, *args, **kw or {}) File "/usr/lib/python2.7/site-packages/openerp/osv/osv.py", line 131, in wrapper return f(self, dbname, *args, **kwargs) File "/usr/lib/python2.7/site-packages/openerp/osv/osv.py", line 198, in execute res = self.execute_cr(cr, uid, obj, method, *args, **kw) File "/usr/lib/python2.7/site-packages/openerp/osv/osv.py", line 185, in execute_cr return getattr(object, method)(cr, uid, *args, **kw) File "/var/packages/OpenERP7.x/target/openerp/addons/base/module/wizard/base_module_update.py", line 42, in update_module update, add = module_obj.update_list(cr, uid,) File "/var/packages/OpenERP7.x/target/openerp/addons/base/module/module.py", line 619, in update_list handler.load_addons() File "/var/packages/OpenERP7.x/target/openerp/addons/web/http.py", line 546, in load_addons m = import('openerp.addons.' + module) File "/usr/lib/python2.7/site-packages/openerp/modules/module.py", line 133, in load_module mod = imp.load_module('openerp.addons.' + module_part, f, path, descr) File "/var/packages/OpenERP7.x/target/openerp/addons/magento_integration-develop/init.py", line 9, in <module> import magento File "/var/packages/OpenERP7.x/target/openerp/addons/magento_integration-develop/magento.py", line 17, in <module> import magentoImportError: No module named magento最下面這個地方，導入時的錯誤，好像是說明了找不到這個名為magento的模塊。這裡可以請各位大俠，為小弟解譯一下嗎？樓上曾提到，按照上述链接步骤进行,需要安装pycountry，這個pycounty是什麼東西呢？該怎麼樣進行安裝，小弟不才，可以麻煩說明一下嗎？
