我嘗試配置mod_wsgi來訪問odoo，謝謝我的域名。 我跟着this tutorial。

但是，當我去我的網站我得到這個錯誤：

您的mod_wsgi是爲不同於您嘗試強制使用的Python虛擬環境或其找到的Python共享庫而編譯的Python安裝。更糟糕的是，它所使用的是用不同寬度編譯的Unicode字符支持。您需要卸載mod_wsgi並從源代碼重新安裝mod_wsgi，並根據您要使用的特定Python版本進行編譯，並在必要時強制它使用正確的共享庫。您可能還需要考慮重新安裝自定義Python版本，以使用與平臺通常被認爲是最佳實踐相符的配置。 Linux系統通常使用4個字節的Unicode，不2.

一些東西供您閱讀：

忽視的事實是關於泊塢後者的談判，所有仍然與普通的Python安裝相關。
