我已经建立了一个odoo11数据库并尝试安装stock模块，但是它将生成python yaml错误。

我也无法安装其他应用，请帮助。
最佳答案
您可能会遇到问题，因为PyYAML进行了一些重大更改，并且依赖于PyYAML的软件包尚未更新和/或尚未固定到较旧的PyYAML版本。
您应该做的是运行pip list并查看您拥有的PyYAML版本。如果该版本> = 4.0，则运行：
pip install -U pyyaml==3.13
PyYAML不在odoo的
requirements.txt中，因此您可能获得了最新版本的PyYAML，该版本不再（不再）兼容。关于python - odoo11库存模块安装上的python yaml错误。 yaml.constructor.ConstructorError:无法确定标签“!python”的构造函数，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/55593400/
