问题描述
我正在尝试按照github页面上链接的说明在Mac上设置odoo。使用以下命令启动服务器时：
python3 odoo-bin --addons-path=addons -d mydb -i base
服务器启动，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。我已经查找了web.login模板，却没有找到任何东西。
解决方法
这是Odoo中的错误。它可能以前是沉默的，但是自从最新版本的Python 3.8起，它现在导致崩溃。您可以暂时降级到早期版本（例如python-3.8.3），直到修复Odoo。

,这个问题的解决方案是降级你正在运行的python版本。如果假设你在 python3.8 上运行，你应该降级到 python 3.6，正如 Husain Rangwala 在这篇文章 https://www.odoo.com/forum/help-1/valueerror-name-node-can-t-be-used-with-none-constant-template-1105-path-templates-t-t-div-t-t-after-updating-to-python-3-8-5-177836 中解释的那样。要在 Python 版本之间切换，请访问 https://hackersandslackers.com/multiple-versions-python-ubuntu/
