收到此錯誤給出：

run: 
Connecting to localhost:35230 
Failed to start session. 
Press ENTER to quit

本地主機上運行我的系統通過xampp，我嘗試默認端口：8080，沒有端口也沒有工作，然後我開始玻璃魚服務器也在工作 http://localhost:35230但仍然得到這個錯誤什麼更多的配置是必需的？

什麼產品BB的您使用的是臺式機或ServerAPI？ –

本地bbcomm進程的默認端口一般爲8194.您需要運行bbcomm.exe進程並通過彭博終端連接到彭博。

嗨我已經運行bbcomm.exe文件，然後也出現同樣的問題。 –

如果您使用的是桌面API，彭博API不會讓您連接到本地主機以外的任何其他機器。這是設計。

如上所述，對於DesktopAPI的默認端口是解釋檢查8194.在BBCOMM.CFG文件，看看是否您正在使用端口8194.

而且直接在命令提示符下運行BBCOMM文件，看看是否出現錯誤。

如果您正在使用ServerAPI讓我知道...
