錯誤：MySQL_python：不支持線程之間的共享連接

Question

我是Python新手，我需要運行我的rails項目，它依賴於Python應用程序。 我使用Python與MySQL和嘗試運行的服務器，但它拋出一個錯誤：

Answer 1

twil是正確的 - 你需要一個不同的端口爲每個Python應用程序。如果你是在Linux上以root身份運行此命令（它會告訴你其他的Python應用程序都runninng）

ps -ef | grep python 

找到這些應用程序正在運行的端口，並選擇不同的端口。您可以使用其他非Python應用程序使用該端口。在這種情況下，你應該看看使用的端口是什麼？

希望這有助於！
