python - 当我尝试运行 Odoo 时，为什么会出现错误 "Name node can' t be used with 'None' constant”？

Question

我正在尝试按照 github 页面上链接的说明在我的 mac 上设置 odoo。使用此命令启动服务器时:

python3 odoo-bin --addons-path=addons -d mydb -i base

服务器启动，我在 odoo 启动页面上看到一个数据库“mydb”。然后，当我单击该数据库时，出现以下错误:

ERROR mydb werkzeug: Error on request:

我不知道从哪里开始这个错误。我查了 web.login 模板并没有找到任何东西。

这是 Odoo 中的一个错误。之前它可能是无声的，但自从最近版本的 Python 3.8 以来，它现在导致崩溃。您可以暂时降级到早期版本(如 python-3.8.3)，直到 Odoo 得到修复。
